The Rapid Androgen Disruption Activity Reporter (RADAR) Test Guideline describes an aquatic assay that utilizes transgenic Oryzias latipes (O. latipes, Japanese medaka) eleutheroembryos at day post hatch zero, in a multi-well format to detect chemicals active on the androgen axis.

Part of Water Quality Set - Buy all four books and save over 30% on buying separately! Bioanalytical Tools in Water Quality Assessment reviews the application of bioanalytical tools to the assessment of water quality including surveillance monitoring. The types of water included range from wastewater to drinking water, including recycled water, as well as treatment processes and advanced water treatment. Bioanalytical Tools in Water Quality Assessment not only demonstrates applications but also fills in the background knowledge in toxicology/ecotoxicology needed to appreciate these applications. Each chapter summarises fundamental material in a targeted way so that information can be applied to better understand the use of bioanalytical tools in water quality assessment. Bioanalytical tools in Water Quality Assessment can be used by lecturers teaching academic and professional courses and also by risk assessors, regulators, experts, consultants, researchers and managers working in the water sector. It can also be a reference manual for environmental engineers, analytical chemists, and toxicologists.

The Third National Conference on Environmental Science and Technology was held in Greensboro, NC, on September 12-14, 2007. This book contains the following topics: pollution prevention, fate and transport of contaminants, bioremediation, bio-processing, innovative environmental technologies, global climate change, and environmental justice.

Volume 1 of the Sustainable Management of Sediment Resources mini-series is the first attempt to fill many of these gaps in knowledge and also in practice. The volume includes sections on: - Sampling - Characterization of contaminants in sediments being bioavailability the main issue - Chemical analysis - Biological analysis - Effect directed analysis and toxicity - Identification evaluation - Benthos sediment quality assessment - Modelling of pollutant fate and behaviour - Sediment quality guidelines This first volume is applicable to a wide audience, from students at the graduate level, to experienced researchers and laboratory personnel in academia, industry and government. This volume also available as part of a 4-volume set, ISBN 0444519599. Discount price for set purchase. - A broad overview on sediment quality and impact assessment of pollutants - Suitable for both newcomers to the field of sediment treatment and specialists alike - Outlines practical examples of methods used in sediment quality analysis

This Test Guideline is designed to assess effects of prolonged exposure to chemicals on the reproduction and survival of the hermaphrodite freshwater snail Lymnaea stagnalis (the Great Pond Snail).

To safeguard public health, the US Environmental Protection Agency (EPA) must keep abreast of new scientific information and emerging technologies so that it can apply them to regulatory decision-making. For decades the agency has dealt with questions about what animal-testing data to use to make predictions about human health hazards, how to perform dose-response extrapolations, how to identify and protect susceptible subpopulations, and how to address uncertainties. As alternatives to traditional toxicity testing have emerged, the agency has been faced with additional questions about how to incorporate data from such tests into its chemical assessments and whether such tests can replace some traditional testing methods. Endocrine active chemicals (EACs) have raised concerns that traditional toxicity-testing protocols might be inadequate to identify all potential hazards to human health because they have the ability to modulate normal hormone function, and small alterations in hormone concentrations, particularly during sensitive life stages, can have lasting and significant effects. To address concerns about potential human health effects from EACs at low doses, this report develops a strategy to evaluate the evidence for such low-dose effects.

Over the past several years, the US Environmental Protection Agency (EPA) has been transforming the procedures of its Integrated Risk Information System (IRIS), a program that produces hazard and doseâ€'response assessments of environmental chemicals and derives toxicity values that can be used to estimate risks posed by exposures to them. The transformation was initiated after suggestions for program reforms were provided in a 2011 report from the National Academies of Sciences, Engineering, and Medicine that reviewed a draft IRIS assessment of formaldehyde. In 2014, the National Academies released a report that reviewed the IRIS program and evaluated the changes implemented in it since the 2011 report. Since 2014, new leadership of EPA's National Center for Environmental Assessment (NCEA) and IRIS program has instituted even more substantive changes in the IRIS program in response to the recommendations in the 2014 report. Progress Toward Transforming the Integrated Risk Information System Program: A 2018 Evaluation reviews the EPA's progress toward addressing the past recommendations from the National Academies.

Wiley StatsRef: Statistics Reference Online is a comprehensive online reference resource which covers the fundamentals and applications of statistics in all fields where it is widely used. This is the most inclusive, authoritative, online reference source available in statistics.

Due to their interesting properties, nanomaterials can be found almost everywhere - from food products to painting and electronic devices. Only recently, scientists started to evaluate the ecological risks evolving from production and exposure of thousands of tones of nanomaterials. This book discusses fundamental principles and latest research results, providing insight into the complex topic for students from all science disciplines.
