Passive sampling of hydrophobic and polar organic chemicals in atmospheric and aquatic environments
Proposed Session Chairs- Eddy Y. Zeng (School of Environment, Jinan University, China)
- Satoshi Endo (Osaka City University, Japan)
- Gi-Beum Kim (Gyeongsang National University, Korea)
- Keith Maruya (Southern California Coastal Water Research Project Authority, US)Session Description:Passive sampling techniques are easy to operate and cost-effective, and hence create new opportunities for monitoring hydrophobic and polar organic pollutants allowing to evaluate their distribution and fate in atmospheric and aquatic environments on a large spatial scale. Being able to determine the occurrence and longer-term trends of organic pollutants would greatly enhance spatial and temporal information which is currently limited. It would also obtain useful data needed to assess long-term human exposure effects. Additionally, passive sampling can measure the metrics that are particularly relevant for environmental dynamics and ecotoxicological effects of contaminants but are difficult to measure otherwise. These metrics include freely dissolved bioavailable concentrations, activities, fugacities, fluxes, and time-weighted average concentrations. However, there are some important and challenging areas for development and field applications of passive sampling techniques that require further improvements. This proposed session will focus on (but not be limited to) the conceptual framework and method development, regional monitoring and case studies, comparison of passive sampling techniques with traditional sampling methods, and potential use of passive samplers for regulatory purposes. The session will also discuss the benefits and challenges in the field application of passive sampling techniques in atmospheric and aquatic environments.

Proposed Session Chairs- Youn-Joo An (Konkuk University, South Korea)
- Koji Arizono, (Prefectural Univ, Japan)
- Hyeon Seo Cho (Chonnam National University, South Korea)
- Denise M. Mitrano (Eawag: Swiss Federal Institute of Aquatic Science and Technology, Switzerland)
- Huahong Shi (East China Normal University, China)
- Wonjoon Shim (Korea Institute of Ocean Science and Technology, Korea, Busan, South Korea)
- Antonia Praetorius (University of Vienna, Austria)Session Description:Global concern over micro- and nanoplastic pollution resulting from our end-of-life plastic has grown rapidly. Significant gaps, however, remain in our understanding of several crucial aspects of exposure and effect assessment which are essential component in ecological risk assessment of nano- and microplastics. While the nano- and microplastic sources are diverse, the relative importance of input pathways has yet to be quantified and relevant transportation and weathering processes need to be elucidated. In addition, the effects of micro- and nanoplastics on aquatic organisms and humans are also yet to be addressed in the environmentally relevant levels. In this session, we therefore invite abstracts which demonstrate recent updates in 1) characterization of nano- and microplastic pollution in urban, terrestrial, freshwater and marine environments including developing a novel method, 2) source, input pathway, transportation and fate including model or experimentally quantified flux and weathering and fragmentation process, and 3) uptake, trophic transfer, and adverse biological effects in soil, benthic and pelagic ecosystems. Depending on the number of abstracts submitted, this session might be divided in three sequential sub-sections mentioned above and separately chaired.
Human exposure to contaminants of emerging concern: monitoring, exposure pathways and risk assessment
Proposed Session Chairs- Da Chen (Jinan University)
- Jeong-Eun Oh (Pusan National University)Session Description:Humans are exposed to a large variety of chemicals of emerging concern (CECs), including halogenated and non-halogenated flame retardants, perfluorinated chemicals, plastic additives, pharmaceuticals and personal care products (PPCPs), pesticides, and many others. The exposure may be via multiple routes, including oral intake, dermal contact, inhalation, and hand-to-mouse transfer. Contamination signatures may vary in regions and time, and are associated with a number of factors, including age class, sex, dietary behavior, and occupation. In addition to the study of general public, subpopulations, such as pregnant women and children, require special attentions on their risks to CEC exposure. Toddlers and children may be subject to elevated exposure to certain groups of CECs leaching from consumer products, absorbed into indoor dust, or present in breast milk. Prenatal exposure may result in exposure in fetus and in newborns, leading to miscarriages, adverse health outcomes, or impacts on mental and physical development of newborns.
Current research on human exposure to CECs remains limited in assessed analytes, elucidation of exposure sources, pathways and health outcomes, and evaluation of prenatal and postnatal exposure. Benchmark data of toxicity are lacking for many CECs, limiting our capability in risk assessments and prevention. Exploration of these themes will advance our knowledge of human exposure scenarios and risks.
Topics of this session include, but are not limited to:
1. Analytical advancements for detecting CECs and metabolites in humans;
2. Human exposure sources and pathways;
3. Contamination residues in human breast milk, serum, and other tissues;
4. Epidemiology studies revealing factors that influence human exposure and biomarkers;
5. Epigenetic studies relevant to environmental chemical exposure;
6. Laboratory animal studies interpreting human exposure outcomes;
7. Metabolism and effects of metabolic modification on toxicity.
The dirty dozen and a few more: persistent organic pollutants in the environment
Proposed Session Chairs- John Elliott (Environment and Climate Change Canada)
- Jung-Hwan Kwon (Korea University)
- TBDSession Description:Research on persistent organic pollutants (POPs) is one of the classic topics in SETAC. POPs are persistent in the environment, have long-range transport and bioaccumulation potential and toxicity. Despite being regulated in most countries and internationally under the Stockholm Convention, POPs, both legacy and novel, continue to contaminate the biosphere. Thus, it is important to know their environmental occurrence, fate, and effects on humans and the ecosystem in order to prevent potential harmful consequences of POPs. Although the scientific community has spent a lot of resources for decades on the legacy and emerging POPs, there are still much things to be revealed to bring research outcomes to global regulatory and management frameworks. It is inevitable to make a global collaboration toward an appropriate assessment and management of POPs due to their transboundary nature. The main aim of this session is to share recent advances in the area of the environmental monitoring, fate, and toxicity of POPs in Asia-Pacific region and the rest of the world. Specific topics in this session include but are not limited to: the occurrence of POPs in various environmental media and biota, source apportionment, regional and global transport of POPs, recent advances in the understanding of the environmental fate of POPs, assessment of bioaccumulation/bioconcentration and trophic transfer, identification of emerging chemicals having POPs-like properties, and toxic effects of POPs in biota.

- Sunghwan Kim, Ph.D (Kyungpook National University, Republic of Korea)Session Description:Human being’s wide reliance on petroleum as an energy source and chemical feedstock requires the production and transportation of crude oil and refined products. Despite technical developments and stringent regulations, accidental spills and intentional discharges of petroleum are frequent around world, especially Asia Pacific regions. Recent examples are the Hebei Spirit oil spill in Korea (2007) and the Deepwater Horizon oil spill in the US (2010). Considering researches following the oil spill is subject to regulatory and legal actions, it is crucial to assess the environmental impact of spilled oil in the framework of environmental forensics. This session will include presentations on recent oil spill experiences and developments in oil spill environmental forensics covering: oil spill case studies in Asia Pacific region, oil spill identification methods, environmental petroleomics, environmental fate of spilled oil, toxicity of petroleum, and ecosystem effects of oil spill
Ideas, tools, and strategies to assess and minimize damages caused by chemical accidents
Proposed Session Chairs- Seung-Ryul Hwang (National Institute of Chemical Safety)
- Seung Hun Hyun (Korea University)Session Description:Due to the continuous growth of chemical industry and the increase in the use and transport of chemicals, the risk of chemical accidents is accordingly increasing. As chemical accidents may cause fatal and irreversible damages to surrounding ecosystem as well as human health, the safety management and the prevention is of the top priority tasks. Along with the efforts, strategies to monitor spilled/released chemicals, to simulate the exposures, to assess/quantify the resulted injuries and harms, and to restore the surroundings should be established in advance for rapid actions. For making reasonable plans, interactive sharing of ideas and opinions from diverse area (e.g., administration, industry, and academia) is strongly recommended. In this session, the main focus is on administrative action plans, framework for damage assessment, and scientific/engineering tools to collect data on chemical accidents and the adverse consequences including monitoring/simulation/assessment/restoration methods. Any kinds of experiences and lessons learned from chemical accidents will be also welcomed.

- Dr. Kurunthachalam Kannan (Wadsworth Center, NYS Department of Health, US)
- Dr. Chunyang Liao (Chinese Academy of Sciences, China)
- Dr. Hyo-Bang Moon (Hanyang University, Korea)Session Description:Anthropogenic activities have produced a large number of organic substances that are suspected of impacting human health and our ecosystems. There are categorized as persistent organic pollutants (POPs), pharmaceuticals, personal care products, surfactants, plasticizers, flame retardants, and others. Considering their environmental and human impacts, it is scientifically and socially important to understand occurrence and fate of toxic organic contaminants in diverse environmental compartments such as air, water, soil, and sediment for the reduction of contamination and management of the environment. Moreover, these organic contaminants cause toxicological effects on wildlife and human health through bioaccumulation/biomagnification processes. This session aims to bring together international researchers who study novel advances in analytical techniques of emerging contaminants, occurrence and fate of toxic organic contaminants in multiple environmental matrices, bioaccumulation processes of contaminants in food-web systems, and source-receptor relationships of these contaminants based on the regional monitoring program (but not limited to these topics), to share scientific experiences, technical methods, and insights for further directions.
Metals in the environment: geochemistry, speciation, transport, and fate
Proposed Session Chairs- Dr. Seunghee Han (Gwangju Institute of Science and Technology, Korea)
- Dr. Yongseok Hong (Korea University, Korea)
- Dr. Saeyun Kwon (Pohang University of Science and Technology, Korea)Session Description:The toxicity and adverse effect of trace metals remain to be a global concern, and understanding fundamental processes controlling the fate of metals is critical to assess diverse types of effects to the environment and ecosystems. In addition, climate change occurring at both local and global scales, ranging from increases in temperature and extreme events to modification of biological activities and organic composition, can affect biogeochemical cycling of metals in significant ways. It is therefore important to better predict the fate of metals in response to climate and other environmental disturbances. We invite presentations describing fundamental processes driving metal biogeochemistry, including oxidation/reduction, methylation/demethylation, adsorption/desorption, dissolution/precipitation, in relation to dynamic environmental factors. Contribution from the areas of physical transport across terrestrial and aquatic environments, fate monitoring and modeling at local, regional, and global scales, remediation strategies and technologies, and assessment of human health effects are also encouraged.

Aquatic and terrestrial ecotoxicology of chemicals
Proposed Session Chairs- Kyungho Choi (Seoul National University, Seoul, Korea)
- Alvina Mehinto (Senior scientist, Southern California Coastal Water Research Project. Costa Mesa, CA)Session Description:Asia Pacific region includes many countries with different stages of economy and industry, leading to the use of and hence contamination by numerous types of chemical stressors in aquatic and terrestrial environments. Such chemicals include traditional contaminants such as heavy metals, phenolics, and persistent organic pollutants, and have caused serious ecological and public health effects. On the other hand, new chemicals have been developed and used in growing quantities without adequate knowledge on their ecotoxicological effects. Many experimental (in vitro, in vivo, or in situ) models have been successfully employed to understand the toxicities of such chemicals and their modes of action. This session is aimed at sharing experiences and information on the ecotoxicology of chemicals of regional concern, and to discuss opportunities of possible collaboration.
Fate and effects of nanomaterials in water and soil ecosystems
Proposed Session Chairs- Youn-Joo An(Konkuk University, Seoul, Korea)Session Description:Nanomaterials can become disseminated directly or indirectly into the ecosystem through various exposure routes. Thus, it is necessary to study the adverse effects of nanomaterials to a range of organisms in water and soil ecosystems, as well as their fate. In addition, the effects of nanomaterials depend on their characteristics including size, surface coating, and dimension, therefore, further extensive studies are needed to better understand their fate and effects as related to their characteristics. In this session, speakers will demonstrate that toxicity is caused by different exposure patterns and sheds insight into the unpredictable exposure scenarios of nanometers and their adverse effects. Through this session, we hope to present recent updates in the fate and effects of nanomaterials in water and soil ecosystems
Toxicology of endocrine disrupting chemicals and their substitutes
Proposed Session Chairs- Kyunghee Ji (Yongin University, Yongin, Korea)Session Description:Many chemicals with endocrine disrupting effects have been used for various purposes in human societies. Due to their diverse physicochemical properties and usage pattern, these chemicals can be released into both natural and built environment, and hence their toxicological consequences are of increasing concern. As more information becomes available for toxicities and adverse health effects of endocrine disrupting chemicals (EDCs), new chemicals have been developed to replace the old EDCs in many products. However, there are significant knowledge gaps in their toxicities on humans and ecosystem receptors. This session is organized to introduce recent research findings on the toxicology of both ‘old’ and ‘new’ EDCs and their substituting chemicals, and to promote discussions among interested environmental toxicologists and environmental health professionals.

- Dr. Siming You (Lecturer in Systems, Power & Energy, School of Engineering, University of Glasgow
James Watt South Building, G12 8QQ, UK)Session Description:Environmental pollution due to human activities has become a growing concern after the green revolution in the 1960s. Soil and water pollution with inorganic and organic pollutants and deterioration of air quality through the various toxic gases produced by industry have become serious global environmental issues. Therefore, environmental remediation has gained significant importance to reduce environmental risks that can cause toxic responses in living organisms, and to ensure the maintenance of sustainable ecosystems.
This session will focus on biochar, a porous carbonaceous material produced through thermochemical conversion of organic materials in oxygen depleted conditions. Biochar is an emerging green environmental sorbent that can serve to maintain environmental quality while reducing contaminant toxicity and bioavailability, and is also documented to mitigate greenhouse gas emissions.
This session invites oral and poster presentations discussing the following areas.
• Fate of contaminants and biochar in the environment
• Mechanisms of interactions between biochar and environmental contaminants
• Sustainable role of biochar to reduce environmental toxicity
• Effect of biochar on greenhouse gas emissions
• Groundwater remediation, and water and wastewater treatment using biochar
• Reductive immobilization of environmental contaminants using biochar
• Remediation of contaminated environments using biochar
• Risks and benefits of biochar application for environmental remediation
• Potential for use of modified biochar for removal of pollutants
• Emerging applications of biochar (e.g. Hydraulic fracturing wastewater)
• Toxicity of contaminants and biochar
Thermal stress on aquatic organisms
Proposed Session Chairs- Jinho Jung (Korea University, Republic of Korea)
- Hiroshi Yamamoto (National Institute of Environmental Studies, Japan)Session Description:Thermal stress is a temperature change that causes adverse effects on organisms that function most efficiently within an optimal range of temperature. Global climate changes and thermal discharges from power plants and industrial facilities can influence water temperature to cause thermal stress on aquatic organisms. Thermal stress may affect community interactions and ecosystem structure by alterations in growth, metabolism and reproduction of aquatic organisms. In particular, thermal stress exerts its toxic effects on individual organism at different levels of biological organization ranging from molecular to behavioral. Additionally, aquatic organisms are subject to anthropogenic chemicals present in runoff or effluents, which is expected to have complex interactions with thermal stress. These multiple stressors can be additive, synergistic, or antagonistic at the individual and population levels. Therefore, understanding thermal stress and its interactions with chemical toxicity is critical to project species resilience in aquatic ecosystems. In this session, presentations addressing these challenges at the molecular, organismal, or population scale in aquatic organisms are welcome.
Ecotoxicology– From gene to ecosystem
Proposed Session Chairs- Jee-Hyun Jung (Korea Institute of Ocean Science & Technology, Republic of Korea)
- Iwata Hisato (Ehime University, Japan)
- Young-Mi Lee (Sangmyung University, Republic of Korea)
- Jae-Sung Rhee (Incheon National University, Republic of Korea)Session Description:- Our session is delighted to welcome the participants from all over the world to attend the SETAC AP 2018. The aim of our session is to increase our understanding of the impact of environmental toxicants and/or stressors on organisms and ecosystems at a wide range of biological levels. More interesting environmental toxicants include oils, heavy metals, endocrine disrupting chemicals, nanoparticles, pesticides, recently emerging microplastics, but are not limited to.
- Our session also included the biomarkers, ecotoxicogenomics, corss-omics and systems toxicology, computational toxicology, harmful effects of a wide range of toxicants, and risk assessment from environmental exposures on molecular levels, cellular, tissue, organism, and community. Both laboratory and field studies will be considered. Regarding gene/genome-based research, studies with animal systems that provide fundamental mechanistic insight into toxic effects on molecular levels are also welcome in general.
OMICS advances in chemical toxicity testing and environmental management
Proposed Session Chairs- Jinhee Choi (University of Seoul, Seoul, Korea)
- Xiaowei Zhang (Nanjing University, Nanjing, China)Session Description:Although, conventional toxicity methods are well established and provide phenotypic endpoints required under current legislation, novel approaches are needed to address the challenges that environmental regulators and the regulated community face today. Environmental OMICS help move standard toxicity testing forward from what it is currently: a prescriptive approach that has not fundamentally changed in over 30 years. We propose to supplement / complement traditional toxicity methods with OMICS methodologies and information. OMICS information will greatly contribute to the regulatory community in areas such as the evaluation of new chemicals prior to market introduction, and filling in for the ERA requirements. OMICS data can also contribute in remediation efforts for adversely impacted areas in which ecosystem chemical contamination has occurred. In this session, potential use of OMICS will be discussed in various aspect of environmental management, including chemical toxicity testing.
Advancing the adverse outcome pathway concept – an international horizon scanning approach
Proposed Session Chairs- Kenneth M. Y. Leung (The University of Hong Kong, Hong Kong, China)
- Xiaowei Zhang (Nanjing University, Nanjing, China)Session Description:The adverse outcome pathway (AOP) framework is a systematic approach for integrating existing knowledge to transparently link mechanistic data (i.e., molecular initiating events) to apical toxicity endpoints (i.e., adverse outcomes). Therefore, AOPs can better inform research and regulatory assessments on chemical hazards. This framework has gradually gained international support since its inception in 2010. To advance the utility of the AOP framework, a ‘Horizon Scanning’ exercise was conducted to solicit questions from global scientific communities concerning the perceived challenges and limitations that should be addressed to realize the full potential of the AOP framework in research and regulatory decision-making. Collected questions were then used to identify key themes that would significantly move the development and application of the AOP framework forward. Subsequently, a SETAC Pellston Workshop was organized in Cornwall, Ontario, in April 2017 with a view to exploring the identified themes. This session will summarize the results from the Horizon Scanning exercise, describe the outcomes of the Pellston workshop, and serve as a platform for scientists to share their views on the future development of the AOP framework, particularly in the Asia-Pacific region. We will, therefore, welcome presentations that would advance the science or application of the AOP framework.
AOP-1: Adverse outcome pathways (AOPs) in chemical regulation
Proposed Session Chairs- Jinhee Choi (University of Seoul, Seoul, Korea)
- Natàlia Garcia-Reyero (US Army ERDC, Vicksburg MS, USA)Session Description:Amid revolutionary changes in toxicity assessment brought about by increasing regulation of chemicals, adverse outcome pathways (AOPs) have emerged as a useful framework to assess adverse effect of chemicals using molecular level effect, which aid in setting environmental regulation policies. AOPs are biological maps that describe mechanisms linking molecular initiating event to adverse outcomes at an individual level. Each AOP consists of a Molecular Initiating Event (MIE), Key Events (KEs), and an Adverse Outcome (AO). AOPs use molecular markers to predict endpoints currently used in risk assessment, promote alternatives to animal model-based test methods, and provide scientific explanations for the effects of chemical exposures. Moreover, AOPs enhance certainty in interpreting existing and new information. The application of AOPs in chemical management will help shift the existing paradigm of chemical management based on apical endpoints toward active application of in silico and in vitro data. In this session, potential of AOP in chemical toxicity testing, development process and its limitation will be discussed. This session is sponsored by the Korean Ministry of Environment through ‘Environmental Health R&D Program’ (2017001370001).
AOP-2: Systematic toxicology approaches to develop an adverse outcome pathway (AOP)
Proposed Session Chairs- Jung-Hwa Oh (Korea Institute of Toxicology)
- June-Woo Park (Korea Institute of Toxicology)Session Description:The adverse outcome pathway (AOP) is a conceptual framework of key events (KEs) from a molecular-level initiating events (MIEs) to adverse effects in organism. This will help us to understand in detail how adverse effects in the body could be occurred by exposure to stressors. In addition, AOPs allow for a move away from the traditional animal-based testing to a more mechanistic interpretation of toxicity. The AOP is progressed by a number of definable KEs which represent the different mechanistic processes, often representing different levels of physiological complexity (e.g. protein, organelle, cellular, tissue, organ, whole organism) eventually resulting in an AO. Overall AOP concepts can be also applied to develop the Integrated Approaches on Testing and Assessment (IATA). To decipher the explicit events leading to AOs, systemic approaches including high-throughput, high-content, and omics technologies have been integrated. In this session, cutting edge technologies which can support a development of AOP and recent systematic toxicology approaches for developing AOPs in addition to some technical challenges and limitations in AOP development will be introduced.
This session is sponsored by the Big Issue Group program through Korea Institute of Toxicology and the National Research Council of Science & Technology (NST) grant by the Korea government (MSIP) (No. CAP-17-01-KIST Europe)
Non-conventional animal models in ecotoxicological and genotoxicological studies
Proposed Session Chairs- Prof. Marcelo L. Larramendy, Ph.D. (School of Natural Sciences and Museum, National University of La Plata, La Plata, Argentina)Session Description:Invertebrate and vertebrate animal models have been used for decades in acute and chronic toxicity tests for hazard identification. They can be very efficient screening systems that have a major role to play in toxicity research, because certain aspects of their biology, physiology and genetic characteristics make them suitable models in ecotoxicological and genotoxicological studies.
We intend to provide an overview on the use of non-conventional, locally available, invertebrate and vertebrate species as experimental models for the study of different toxicological aspects induced by environmental pollutants in both aquatic and terrestrial ecosystems.
We shall aime to shed some light on the matter, whilst offering relevant tools for evaluating risk and to provide a framework of practical discussions. These will foster decisions and actions required to reduce environmental health risk against environmental stressors.
Combining bioanalytical toxicology and chemistry – the future for drinking water quality assessment
Proposed Session Chairs- Dr. Johan Lundqvist (Swedish University of Agricultural Sciences, Uppsala, Sweden)
- Prof. Agneta Oskarsson (Swedish University of Agricultural Sciences, Uppsala, Sweden)
- Prof. Karin Wiberg (Swedish University of Agricultural Sciences, Uppsala, Sweden)Session Description:The safety of drinking water is of utmost importance for public health. Contamination with micropollutants is an issue of great concern, considering the high consumption of drinking water, 2-2.5 L per person and day. Occurrence of a vast number of chemicals, even at low concentrations, may constitute a health risk. Target chemical analysis is used to screen for the presence of well-known and emerging micropollutants in drinking water. However, chemical analysis alone can neither assess the potential mixture effects by exposure to multiple chemicals nor alone identify unknown toxic compounds.
Tens of thousands of synthetic chemicals are used and spread into the environment with limited knowledge on their toxicity, resulting in an increasing risk of contamination of drinking water. A new paradigm for drinking water quality assessment is therefore urgently needed. Effect-based toxicity bioassays, representing key toxicity pathways, can be used to assess the total toxic potential in drinking water samples, regardless if the toxicity is caused by known or unknown compounds.
Recently, multiple reports have been published describing results where the total toxicity of drinking water samples has been investigated with bioanalytical tools. This session will review the rapidly expanding scientific field of effect-based assessment of drinking water quality.
Whole Effluent Toxicity and Its Applications
Proposed Session Chairs- Norihisa Tatarazako (Ehime University)
- Hiroshi Yamamoto (National Institute for Environmental Studies)Session Description:The number of chemical substances produced, used, and discharged into the environment has steadily increased and the one registered in Chemical Abstracts Service excessed 130 million by the end of 2017. Since the chemical management based on individual chemicals had reached to the limit, the direct assessment and management of effluent from industrial factories and municipal wastewater treatment plant has recently been used to complement the individual approach such as whole effluent toxicity (WET) in the US started in 1995. In Asia-Pacific region, Korea started the WET in 2011 and Taiwan started in 2013 while China and Japan are in process of implementing the similar system. Currently several application projects are going on now, including developing test methods using domestic species and simplified methods, and the toxicity reduction evaluation (TRE)/toxicity identification evaluation (TIE) procedure. This session accepts all these applications and basic studies relevant to WET type approach.

Yellow Sea Ecosystem: Coastal pollution, ecosystem threats, and environmental health
Proposed Session Chairs- Jong Seong Khim (Seoul National University, Korea)
- Tieyu Wang (Chinese Academy of Sciences, China)
- Jing You (Jinan University, China)Session Description:Coastal ecosystems have long been deteriorated by various pollution sources mainly from the human activities and marine pollution becomes common and significant issues worldwide. In particular, the continuing and heavy industrialization in burgeoning East Asia resulted in increasing coastal and marine pollutions during the past half century. The increasing concerns on the Yellow Sea ecosystem would not be a local issue considering the huge coastal ecosystem services and economic importance in the neighboring countries in Asia. More recently, multiple stressors through continuing coastal development including a large scale reclamation, land-based coastal pollution, and sometimes accidental oil spills resulted in ecosystem threats and negative effects on human well-being. Recent reports also emphasized the ecosystem deterioration by over-exploitation, introduction of alien species, and coastal pollution by marine litters in given region. However, the systematic and integrated approach or program in the Yellow Sea coastal environment has been far limited. Upon the scientific needs and challenges on solving the coastal pollution issues around the Yellow Sea region, the session of “Yellow Sea Ecosystem” will provide a platform for the next generation to share scientific knowledge and improvement of our understanding on the Yellow Sea ecosystem. The session will specifically target the status of coastal pollution, ecosystem threats, and environmental health issues relating to the Yellow Sea region but not limited to the regional issues.
From field to fork: Mitigating human health risks from contaminated agricultural soils and products
Proposed Session Chairs- Dr.Cheng GU (Nanjing University, China)
- Dr.Huan ZHONG (Nanjing University, China & Trent University, Canada)
- Dr.Erin Bennett (Editor-in-Chief, Bulletin of Environmental Contamination and Toxicology & University of Windsor, Canada)Session Description:Session description: Consuming agricultural products is one of the major pathways of human exposure to metals and other contaminants. While much progresses have been made in understanding: (1) Metal biogeochemistry and bioaccumulation in farming systems; and (2) Dietary exposure to metals and associated health risks, systematic understandings about the whole process of metal flux from soil to food, and then to human beings are generally lacking. Especially, the potential impacts of novel techniques of soil remediation on the risk of metals in agricultural products are poorly understood. In this session, we encourage presentations which would improve our understanding and ability to understand or control metal flux ‘from field to fork’. Talks linking metal biogeochemistry/ metal remediation efforts and health risks of metals are particularly encouraged.
Emerging Big Data in Environment Management
Proposed Session Chairs- Zhang Bing (Center for Environmental Management and Policy Analysis School of Environment, Nanjing University)
- Zhang Ning (Department of Economics, College of Economics, Jinan University)Session Description:Improving environment management largely depends on full awareness of reality. The development of environment monitoring method and emerging Big Data technology provides us more chance to get deeper cognition on environment issues, thus more effective management strategy and could be achieved with sufficient application of Big Data.
This session could include but not limited in the following 2 topics. First, emerging new data opportunity. New technology extend our ability to access more data about environment, such as people’s health, behavioral microeconomics (such as residents’ energy and water use, firms pollutants emission behavior), climate change’s effect and so on, which brings chance to seek into more environment issues.
Second, application of Big Data technology in government decision-making. It can include research related to environment and public health, valuation of environment production, pollution control plans, relationship between economics and environment quality, and many other topics, which could offer information support for optimal decision.

- Patrick Guiney (University of Wisconsin, USA)Session Description:This session invites presentations on the use of multiple lines of evidence (LOEs) in weight of evidence (WOE) approaches to the assessment and management of chemicals in the environment. Increasingly, WOE is being applied by regulators, researchers and industry to provide greater certainty in the assessment of cause in exposure and effects assessment. A number of approaches have been developed, and examples of these and case studies of chemicals risk assessment, regulation and management, in the Asia/Pacific region and beyond, are particularly encouraged. Topics of interest for this session include: selection of appropriate LOEs for use in WOE applications; WOE in exposure and effects assessments; employing WOE in chemical classification and labelling; applying WOE in retrospective and prospective risk assessments; risk characterization for both human health and ecological endpoints; and the application of WOE in the derivation of environmental quality benchmarks (e.g. water quality criteria, sediment quality guidelines, safety standards for chemical contaminants, etc.). Abstracts regarding the advantages and disadvantages of various WOE approaches, frameworks and schemes that may instigate debate and discussion are also highly supported.
Science and data for chronic degenerative diseases with exposure to environmental pollutants
Proposed Session Chairs- Han Jin (Inje University)
- Youngmi Kim Pak (Kyung Hee University)Session Description:Dioxins and furans are a group of chemically-related compounds that belong to the persistent environmental pollutants (POPs). POPs accumulate through the food chain, mainly in the fatty tissue of animals and exert highly toxic effects including reproductive and developmental problems, damage the immune system, and interfere with hormones (insulin resistance), thus insulin resistance syndrome (or metabolic syndrome).
Due to the omnipresence of POPs, which include the most toxic dioxins, all people have background exposure to diverse chemicals in mixture. The quantitative chemical analyses of dioxins, furans and other chemicals in mixture require sophisticated methods and are available only in a limited number of laboratories around the world, Furthermore the cost of the analysis is prohibitively expensive even for one kind of POPs and frequently need large amount of blood sample. Even though experts suspected that exposure to POPs and other endocrine disrupting chemicals might cause metabolic syndrome and related chronic degenrative diseases, these limitations made it almost impossible to overcome these barriers.
In this session three leading Korean scientists will discuss how cell based assays could overcome those barriers. The importance of the mitochondrial function in understanding the pathogenesis of chronic degnerative diseases, will be also discussed, focusing on metablic syndrome.

Derivation and Application of Water and Sediment Quality Guidelines
Proposed Session Chairs- Jenny Stauber (CSIRO, Sydney Australia)
- Kenneth Leung (University of Hong Kong, Hong Kong)
- Michael Warne (Coventry University, UK)Session Description:Water and sediment quality guidelines are used throughout the world to monitor and regulate chemical contaminants to protect aquatic ecosystems. Despite recent advances in regulatory frameworks, guideline derivation and implementation in the Asia Pacific region for chemicals remains challenging due to a lack of ecotoxicity tests with endemic species, lack of water quality monitoring data to help derive site-specific criteria (e.g. Dissolved Organic Carbon, DOC) and inability to account for multiple stressor effects and mixtures, as well as inadequacy in associated policy and legal frameworks. Regulation of metals is particularly complex, as metal bioavailability in freshwaters is strongly influenced by water quality parameters such as pH, DOC and hardness. Modelling approaches to normalise metal toxicity data to take into account bioavailability in guideline derivation have been developed for some time and these include the biotic ligand model (BLM) and multiple linear regression (MLR) models. However due to their complexity, the use of models in regulation for deriving and applying criteria has lagged behind their development. The aim of this session is to share expertise on the latest approaches for guideline (criteria) derivation, validation and application in marine and freshwater systems. Papers on research underpinning guideline development, covering organic and inorganic chemicals in waters and sediments, are encouraged. The effects of water and sediment quality parameters on contaminant bioavailability and toxicity, development of toxicity tests with local species and use of tiered approaches in regulatory frameworks are just some examples of topics that will be included to ensure that evidence-based approaches are used in environmental regulation across the region. Papers on lessons learnt from other jurisdictions are also welcome.
Indigeneity and Science: A collaborative work in progress
Proposed Session Chairs- Ross Smith (Hydrobiology Pty Ltd)
- Bradley Moggridge (University of Canberra/Institute of Applied Ecology)Session Description:Scientists within SETAC are tackling complex environmental questions around the fate and effects of contaminants, and their implication for environmental and human health. While there are attempts at involving and sharing this science with relevant communities, much research is conducted within the bubble of discipline-specific scientific communities. When research takes place on Indigenous lands, the social aspects of our science come to the forefront. Indigenous peoples rely on their traditional lands to ensure social, cultural, and spiritual well-being. Conducting western science on traditional lands must utilise an inclusive approach predicated on respectful and reciprocal engagement. This session aims to highlight collaborative research efforts with Indigenous communities, illustrate the strengths and challenges of successful collaborations that bridge research and community engagement, and discuss links between Western science and traditional knowledge systems. Additionally, the expression of indigenous 'knowing', formed through intimate inter-generational relationships with environment, have a valuable role in informing scientific research and policy-making. Topics that will be encouraged and solicited for this session include: community engagement and education related to research on Indigenous lands; linking traditional knowledge and Western science; development of effective community-based monitoring programs; and initiatives to include Indigenous communities in science and policy decisions; among others.
Towards sustainable environmental quality: Identifying priority research needs for Asia-Pacific
Proposed Session Chairs- Prof. Bryan Brooks (Baylor University)
- Prof. Kenneth Leung (University of Hong Kong)
- Prof. Jing You (Jinan University)Session Description:The Global Horizon Scanning Project aims to identify priority future research questions as identified by environmental scientists and engineers working in government, academia and business around the world. Due to the size and diversity of the Asia-Pacific region, two Global Horizon Scanning Workshops were held for Asia-Pacific in Singapore and New Zealand. The aim of this synthesis session is to present the results from these workshops and to look further into the main questions and research needs. We propose to specifically invite integrated presentations focusing on the importance of groups of related priority questions in various themes. At the end of the session, we plan to have an open discussion period for engagement with session attendees. The results of this project directly contribute to the mission of SETAC to achieve Environmental Quality Through Science.
Derivation of Priority Substance List and Environmental Quality Standard for micro-pollutants in aquatic environment
Proposed Session Chairs- Jong-Hyeon Lee (EH R&C Co., Incheon, Korea)
- Tae-Jin Park (National Institute for Environmental Research, Incheon, Korea)Session Description:Water quality authorities from Asian-Pacific countries have the same goal to develop the priority substance list and to derive Environmental Quality Standard (EQS). Development of the priority substances list is the first step for derivation of EQS and an essential part in the environmental quality management. Different approaches including monitoring- and modeling-based approach have been used to develop the priority substance list. To derive EQSs, species sensitivity distribution is required to be built for indigenous species in each countries. Site-specific water chemistry needs to be incorporated into the development procedure of EQS for several metals. All of these processes are based on the same scientific background and ecotoxicity testing methods. During decades, many research experiences and new approach for the derivation of EQS have been accumulated from Asian-Pacific Regions including Australia and New Zealand, China, Japan, and South Korea, etc. This session will summarize the overall experiences and describe the outcomes from AP regions. We will welcome presentations focusing on their experiences to develop the priority substance list and EQSs.
