The Ecological Risk Assessment Specialty Group (ERASG) is currently planning several workshops, including such topics as regional risk assessment, invasive species, climate change, statistical methods, and the integration of human and ecological risk assessment. Anyone with an interest in ecological risk assessment is encouraged to join, from eco-risk practitioners to decision makers relying on these analyses for more effective decision making. We encourage SRA members from all sectors to join the ERASG.. Ecological risk assessment focuses on evaluating the impacts of human activities on ecological systems and the services they provide. As with human health risk assessment, ecological risk assessment has its roots in estimating exposure and risk or hazard from chemicals in the environment, but has expanded in recent years to include the wide range of stressors facing ecological receptors. Risks due to invasive or non-indigenous species, genetically modified organisms, and climate change are ...

I have enjoyed 18 years of being a SETAC member, joining as a graduate student in 1995 then full membership after earning my PhD in 1999. Both my MS and PhD advisors, Drs. Jerry Farris and John Rodgers, emphasized the importance of SETAC through their own service to the society. It was a natural progression for me to not only attend annual meetings, but also to begin serving the society which continues to provide me countless professional opportunities.. Trained in aquatic ecotoxicology, I currently serve as a research ecologist in the Water Quality and Ecology Research Unit of the USDA Agricultural Research Services National Sedimentation Laboratory located in Oxford, MS. For the last 13 years, my areas of research have focused on contaminant fate and effects, as well as designing new agricultural management practices to improve water quality. I spend much of my time in drainage ditches, studying how these systems function as wetlands and how management techniques can improve their ...
This paper aimed to evaluate the test results of acute toxicity on effluent samples which were exempted from applying of ecotoxicity criteria. Total 316 effluent samples which were free from controlling of ecotoxicity regulation, were tested. Ratio of effluent samples which were exceeded the ecotoxicity criteria (TU > 1) indicated 23.7%. This ratio was a little bit higher than previous study (22.7%) on effluent samples which were controlled under ecotoxicity criteria. These results mean that our ecotoxicity management system is not appropriate and applying of ecotoxicity criteria to all effluent samples (82 industry categories) were needed in order to improve our ecotoxicity system. In addition, the same numeric criteria (TU 1 or 2) for all industry categories were proposed in consideration of these results. Ratio of effluent samples which exceeded the ecotoxicity criteria (TU > 1) with D. magna indicated 23.7%. However V. fischeri showed 14.6%. As a acute toxicity test organism, D. magna seemed ...

This article focuses on one specific alternative method for the assessment of hazards of substances, the weight-of-evidence approach (WoE approach). In addition, some other alternative methods for prediction of chemical properties like read-across assessment or use of in silico methods are briefly described.. Two reasons support the use of alternative assessment methods: alternative methods for hazard assessment are necessary, as animal testing should be avoided if possible. On the other hand, there is the problem that for specific situations reliable information needed for assessing the hazard potential of a substance is missed when only the established standard assessment schemes, which consist mostly of laboratory tests, are used. The latter leads to misjudgment of substances, which need to be identified as SVHC. To illustrate this point, a small number exercise can be employed: there is an obvious mismatch between the number of substances registered under REACH and the number of substances ...

The need for alternative approaches to the use of vertebrate animals for hazard assessment of chemicals and pollutants has become of increasing importance. It is now the first consideration when initiating a vertebrate ecotoxicity test, to ensure that unnecessary use of vertebrate organisms is minimized wherever possible. For some regulatory purposes, the use of vertebrate organisms for environmental risk assessments has been banned; in other situations, the number of organisms tested has been dramatically reduced or the severity of the procedure refined. However, there is still a long way to go to achieve a complete replacement of vertebrate organisms to generate environmental hazard data. The development of animal alternatives is based not just on ethical considerations but also on reducing the cost of performing vertebrate ecotoxicity tests and in some cases on providing better information aimed at improving environmental risk assessments. The present Focus article provides an overview of the ...

Nationally and internationally, soil contamination requiring remediation is a major challenge of concern. It has been estimated by The European Environment Agency that approximately 250,000 sites in the EEA member countries require some kind of action. Ecological Risk Assessment of contaminated land always promotes lively dialogue amongst soil scientists, ecotoxicologists, regulators and local authorities. On the one hand, it seems very obvious and simple, but at the same time difficult to simplify and predict in detail and may, hence, be neglected and circumvented. Via the European Framework R&D project - LIBERATION - the Section of Soil Fauna Ecology and Ecotoxicology published a Decision Support System (DSS) for evaluating ecological risk at contaminated sites. This DSS is not a comprehensive "all-you-need-to-have" document for managing risk of contaminated land, as it focuses primarily on supporting decisions made when assessing risk to the terrestrial environment. The main objectives of the ...

The first objective of the Nord-Cotentin working Group (GRNC) was to assess the radiological risk due to past and recent discharges of the nuclear facilities of the Nord-Cotentin region of France. Now, at a second stage, the group is working on the assessment of the risk due to the corresponding chemical releases. One step of this assessment is to build up a common tool to estimate the level of pollutants in the environment. To perform this objective, engineers and experts from environmental toxicology/chemistry and radioecology organizations are working together, within the framework of the GRNC, to model environmental dispersion and transfers and exposures to pollutants. This paper deals with atmospheric sources of pollutants and terrestrial environmental contamination. Three specific facilities were identified as atmospheric sources of chemicals in La Hague nuclear site: the central boiler house (since 1964), the reprocessing units, UP2 and UP3 (since 1966), and the incinerator (since 1995). ...
The largest oil spill in U.S. history, infused with dispersants released into the waters of the northern Gulf of Mexico in response to this still-unfolding disaster, has created an unprecedented threat to the ecology of coastal and marine communities. To date, most efforts have been directed towards halting the spill or documenting its current state. With apparently limited ecotoxicological information, governmental and private entities are preparing to create and fund large-scale and long-term monitoring efforts across the Gulf. We propose to assemble ecologists, chemists, and ecotoxicologists with experience in coastal oil spills, in coastal and pelagic ecology, and who are collecting in situ data in the wake of the Gulf Coast spill. Our group will create a framework outlining potential ecotoxicological impacts upon Gulf populations and communities with a primary goal of providing this information to decision making and funding entities in an expedited manner. collapse ...

The plenary sessions provided the platform for interesting discussions on topical issues ranging from general toxicology to specialized ecotoxicology issues. Some of the highlights of the plenary presentations are described below. The plenary lecture delivered by Michiel Daam (Portugal) on "Aquatic ecotoxicology of pesticides under temperate versus tropical climates" demonstrated that there were no consistent differences between the degradation rates of some pesticides between temperate and tropical climates as well as no differences in sensitivities between temperate and tropical species to the pesticides. He also shared with the participants that with a creative mind, a lot can be achieved with very limited resources, as is usually the case in most African countries. This was a very welcome message for all participants..

So far, ecotoxicological studies used biomarkers of exposure or of effects in order to investigate the impacts of contaminated areas on biota (Peakall, 1994 [6]). However, although these results are important in the ecotoxicological risk assessment, biomarkers are very specific and only provide information on the biological processes or physiological pathways targeted by the biomarkers experimenters choose to test (Monsinjon and Knigge, 2007 [5]). In recent years, proteomics have become a major tool in ecotoxicology, as they provide a global insight into the mechanism of action of pollutants without the need of hypothesis testing or any preconception on the biological processes likely impacted (Gismondi et al., 2015; Trapp et al., 2015 [7]; Truebano, 2016 ...

AEP completes transmission line rebuild and maintenance work across hundreds of miles of transmission line right-of-way (ROW) in numerous states across the country every year. These major projects require significant capital investment and the uncertainties associated with natural resource regulatory constraints can drive up the construction costs. In order to provide EPC bidders with a better understanding of ecological constraints and natural resource permitting requirements along project routes, GEI worked with AEP to develop and complete these innovative preliminary risk assessment reports. These ecological risk assessments were a new effort to identify red flag environmental issues early in the process, obtain more accurately priced EPC bids, and develop environmental permitting cost estimates for project construction budgeting purposes.. As part of this effort, wetlands, streams, threatened and endangered species or their habitat, and areas of soft muck soils or ponding waters were ...

As mentioned above, though the United States did ban the use of PCBs, there is the possibility that they are present in products made before the PCB ban in 1979. The Environmental Protection Agency released its ban on PCBs on April 19th, 1979.[10]According to the US Environmental Protection Agency, "Although PCBs are no longer being produced in this country, we will now bring under control the vast majority of PCBs still in use," said EPA Administrator Douglas M. Castle. "This will help prevent further contamination of our air, water and food supplies from a toxic and very persistent man-made chemical."[10]. PCBs has been tested on laboratory animals and have caused cancer and birth defects. PCB is suspected of having certain effects on liver and skin of humans. They are also suspected of causing cancer as well. EPA, "estimates that 150 million pounds of PCBs are dispersed throughout the environment, including air and water supplies; an additional 290 million pounds are located in landfills in ...

Ecological risk assessments and risk management decisions are only as sound as the underlying information and processes to integrate them. It is important to develop transparent and reproducible procedures a priori to integrate often-heterogeneous evidence. Current weight-of-evidence (WoE) approaches for effects or hazard assessment tend to conflate aspects of the assessment of the quality of the data with the strength of the body of evidence as a whole. We take forward recent developments in the critical appraisal of the reliability and relevance of individual ecotoxicological studies as part of the effect or hazard assessment of prospective risk assessments and propose a streamlined WoE approach. The aim is to avoid overlap and double accounting of criteria used in reliability and relevance with that used in current WoE methods. The protection goals, problem formulation, and evaluation process need to be clarified at the outset. The data are first integrated according to lines of evidence ...
Toxicity of the purple mucus of the polychaete Halla parthenopeia (Oenonidae) revealed by a battery of ecotoxicological bioassays
The use of biomarkers is considered a promising alternative, or complement, to traditional ecotoxicological assays. Toxic effects are often initially manifested at the molecular or biochemical level, biomarkers are therefore used as sensitive indicators of toxic exposure. Ideally, biomarkers would also indicate reduced fitness and possible later effects at the individual or population levels. However, implementing biomarkers in ecotoxicology is challenging and few biomarkers have an established connection to reduced individual fitness. The aim of this thesis was to increase the value and improve the interpretation of biomarker responses in ecotoxicological studies by examining the impact of confounding factors and the relationship between oxidative biomarkers and reproductive effects in crustaceans.. The sensitivity of biomarkers was confirmed in paper I as toxic effects of pharmaceuticals with conserved drug target orthologs were observed at the molecular and biochemical levels both earlier and ...

2002). However, perhaps more importantly we do not know the genetic origins of the regulatory switch(es) that cause the constitutively high levels of expression of GSTs in crops. 2 Herbicide Safeners and GST Regulation Herbicide safeners are compounds that enhance herbicide tolerance in cereal crops largely by increasing the expression of detoxifying enzymes including GSTs. As weIl as enhancing GSTs, safeners also increase the synthesis of glutathione and the levels of ATP-binding cassette (ABC) transporter proteins that deposit the herbicide conjugates in the vacuole, thereby co-ordinately increasing the capacity of the glutathione conjugation detoxification pathway (Davies and Caseley 1999). In every case where correlations between enhancement of GST Metabolism by Glutathione S-Transferases 27 activity and expression of the respective genes have been examined, it appears that increases in GST activity can be accounted for by an increase in the levels of the respective proteins brought ab out ...

Figures in bold are based on read-across Classification according to DSD (Dangerous Substance Directive 67/548/) As all ecotoxicity values (corrected and uncorrected) as given in Table 32 are below 1 mg/L. Based on these results it is proposed to classify N, C12 -14 alkyl-1,3-diaminopropane as R50. Alkyl-1,3-diaminopropanes are readily biodegradable.

The Journal of Xenobiotics publishes original studies concerning the beneficial (pharmacology) and detrimental effects (toxicology) of xenobiotics in all organisms. A xenobiotic ("stranger to life") is defined as a chemical that is not usually found at significant concentrations or expected to reside for long periods in organisms. In addition to man-made chemicals, natural products could also be of interest if they have potent biological properties, special medicinal properties or that a given organism is at risk of exposure in the environment. Topics dealing with abiotic- and biotic-based transformations in various media (xenobiochemistry) and environmental toxicology are also of interest.. Areas of interests include the identification of key physical and chemical properties of molecules that predict biological effects and persistence in the environment; the molecular mode of action of xenobiotics; biochemical and physiological interactions leading to change in organism health; ...

Several of the pressing scientific challenges in the filed of environmental toxicology are to understand the basic mechanisms of chemically-induced toxic substances and of the design, interpretation, and extrapolation of data from non-human bioassay systems to the human situation. The objective is to offer a new paradigm, namely the idea that cytotoxic and epigenetic effects of chemicals can contribute to many toxic endpoints in human beings. We will speculate that the disruption of calcium homeostasis by a wide variety of chemicals and the conditions of their use might provide an unification of mechanisms leading to either cytotoxicity or epigenetic changes. Depending on the conditions, the effects of this disruption, a pleiotropy of diseases might result, namely, embryotoxicity, teratogenesis, tumor promotion, immune modulation, neurotoxicity, and preproductive dysfunction. In summary, there are at least three biological endpoints at the cell level which chemicals can influence - mutations, cell death

Concerning rats, NMRI-mice, B6C3F1 mice, guinea pigs and hamsters the NMRI-mice are the most susceptible species (lowest LD50 = 142 mg/kg bw in male NMRI mice) and the dose- response relation was very steep. With an oral dose of 200 mg/kg bw none of the treated B6C3F1- mice, hamsters or guinea pigs died. For male rats a LD50 = 3622 mg/kg bw was found. Based on the broad LD50 values reported in different species and strains a weight-of-evidence approach was taken to conclude that ditolylether should be classified with Acute Tox.4, H302 and no defined LD50 vaue is selected for the risk assessment. A discriminating dose (rat) , 2587 mg/kg bw (2.5 ml/kg bw) for the acute dermal toxicity was determined in an experiment in rats. For acute inhalation toxicity a discriminating dose , 521 mg/m³ (rat, female) and a discriminating dose , 671 mg/m³ (rat, male), was found. The whole body exposure for 7 hours of the saturated test atmosphere caused no mortality and no signs of toxicity. The LC50 value could ...
Assessment of skin irritation was tested as a weight-of-evidence approach -A first in vitro study was conducted to study corrosive properties by means of a three-dimensional EST-1000 human skin model (Flügge, 2013a). The test item containing ,95% active ingredient was applied to the skin surface. In comparison to the negative controls, the mean viability of cells exposed to the test item was 78.8% after a 3-minute exposure period and 74.9% after a 1-hour exposure.The values were well above the cut-off percentage cell viability values distinguishing corrosive from non-corrosive test items of ,50% or ,15% for a 3-minute or 1-hour treatment, respectively. Therefore, the test item was non-corrosive in this skin model and is predicted to be non-corrosive to human skin. -A second in vitro study was conducted to determine irritating properties by means of the three-dimensional EST-1000 model of human skin (Flügge, 2013b).

Bisphenol F (BPF) has been frequently detected in various environmental compartments, and previous studies found that BPF exhibits similar estrogenic and anti-androgenic effects on the mammalian endocrine system to those of bisphenol A (BPA). However, the potential disrupting effects of BPF on aquatic organisms and the underling disrupting mechanisms have not been investigated. In this study, the potential disrupting mechanisms of BPF on the hypothalamic-pituitary-gonadal (HPG) axis and liver were probed by employing the OECD 21-day short-term fecundity assay in zebrafish. The results show that BPF exposure (1 mg/L) impaired the reproductive function of zebrafish, as exemplified by alterations to testicular and ovarian histology of the treated zebrafish. Homogenate testosterone (T) levels in male zebrafish decreased in a concentration-dependent manner, and 17β-estradiol (E2) levels increased significantly when fish were exposed to 0.1 and 1 mg/L BPF. The real-time polymerase chain reaction was ...

ABSTRACT: The conceptual model on which chemical assessment of pollutants is based is flawed. The assumption in ecotoxicology ‹ that pollutants cross the biological membrane only by passive diffusion of their solute phase (diffusion model) and thus, that only water-soluble pollutants are biologically available ‹ is inconsistent with the biologists¹ understanding of the role and functioning of the biological membrane. The biological membrane both isolates organisms, cells and organelles from their external environments and regulates cross-membrane trafficking of polar and non-polar substances. Trafficking regulation is a function of proteins dissolved within the membrane. An alternative protein model for pollutant uptake and elimination is proposed that provides a credible explanation of how solid-phase pollutants, such as those bound to aquatic sediments and soils, may be readily incorporated by living organisms. Current chemical testing is likely to underestimate the risk posed to ...
Research in the Swanson Lab Group is centered around northern aquatic ecology and ecotoxicology. We apply chemical tracers, such as stable isotope, fatty acid, and otolith microchemistry analyses to reconstruct fish ecology and fish life history. We relate ecology and life history to contaminant accumulation, and aim to understand how contaminant concentrations in fishes will respond to anthropogenic stressors, such as climate change.
Use of biochemical, physiological, anatomical, reproductive and behavioral characteristics of wild terrestrial vertebrates to assess contaminant exposure and effects has become commonplace over the past 3 decades. At the level of the individual organism, response patterns have been associated with and sometimes causally linked to contaminant exposure. However, such responses at the organismal level are rarely associated with or causally linked to effects at the population level. Although the ultimate goal of ecotoxicology is the protection of populations, communities, and ecosystems, most of the existing science and regulatory legislation focus on the level of the individual. Consequently, much of this overview concentrates on contaminant effects at the organismal level, with some extrapolation to higher-level effects. In this chapter, we review the state of the science for the evaluation of biotic end-points used to assess contaminant exposure and effects at or above the level of the...
