Book Description
This CD-ROM provides the facts, abstracts and figures needed to build environmental models together with information on the environmental effects of chemical substances. The data has been rigorously selected from scientific journals covering 25 years. Environmental models included cover a wide range of topics, including eutrophication, dispersion of chemical compounds, growth and competition of different organisms as well as models which describe global environmental cycles. Ecotoxicological information on substances includes the water concentrations at which aquatic organisms are affected by the chemical compounds. These concentrations are used in the regulation of releases and for calculating safe concentration levels in the environment. The growth of environmental toxicological data and the growth of different types of environmental models has been a major new development in this field. ECOTOX: Ecological Modelling and Ecotoxicology presents ecotoxicological information about more than 2000 chemical substances, including such data as growth parameters, lethal concentrations (LC50), emissions, degradation of chemical substances, background concentrations, concentration factors, biological effects, octanol/water partition coefficients, excretion and uptake rates, emissions and composition of living organisms. Accompanying this information are the constants and equations to be used in environmental models, and abstracts from scientific journals to give an explanation concerning the scope of the data. All this information is directed towards environmental modelling, administration of environmental regulations, scientific models, environmental policy making and environmental impact assessment.

Book Description
Ecotoxicology is the science of toxic substances in the environment and their impact on living organisms. Today we use many more chemicals in everyday life than we did 30-40 years ago. Our knowledge of the fate and effect of such chemicals in the environment has not yet followed the rate of chemical innovation in spite of our expanding knowledge of ecotoxicology. About 50,000 different chemicals are produced on an industrial scale, but we have only sufficient data to evaluate the environmental consequences of a few per cent of these. The need for ecotoxicological knowledge has never been more pronounced than it is today. Even more resources must be allocated in this field in the near future, if we are to be able to cope with the threat of more toxic chemical compounds in our environment. This book outlines the state of the art of modelling the fate and effects of toxic substances in the environment. Modelling in ecotoxicology differs from modelling in other fields by the great lack of data. The quality of the models is very dependent on the parameters used, and as we do not have a wide knowledge of parameters in ecotoxicological processes, good parameter estimation methods are crucial for ecotoxicolocal models. A comprehensive review of available parameter estimation methods is therefore included in this volume. Model examples and case studies have also been included to illustrate the difficulties and short comings in practical modelling.

Book Description
Ecotoxicology Essentials: Environmental Contaminants and Their Biological Effects on Animals and Plants provides a fundamental understanding of this area for students and professionals in ecotoxicology, ecology, conservation, chemistry, public health, wildlife management, fisheries, and many other disciplines. Although new chemicals and potential problems are developed every year, a basic education is essential to address these new challenges, and this work gives such training. Written with the regulatory framework in mind, the material guides readers on modelling, how to conduct assessments, and human and wildlife risk, focusing on effects on animals rather than transport of chemicals. Simple discussions of chemistry are complemented by coverage on the behavior of the animal, dynamics of the ecosystem, real-life situations like drought, and predators in the system – i.e., the natural system versus the lab setting. The book’s first section contains chapters on the principles of contaminant toxicology including a brief history of the science of ecotoxicology, basic principles of the science, testing methods, and ways of determining if animals have been exposed to either acute or chronic concentrations of contaminants. The second section deals with the primary classes of contaminants including their chemical characteristics, sources, uses, and effects on organisms. The third section focuses on more complex issues such as the regulation of pollution, population and community effects, risk assessment and modelling. Uses examples from both aquatic and terrestrial environments and species Includes a Terms to Know section and a list of study questions in each chapter, fostering a greater understanding of the issues Focuses on the effects of contaminants on wildlife while providing enough chemistry to allow a detailed understanding of the various contaminant groups Emphasizes natural examples and 'real' species, rather than laboratory studies on only a handful of organisms Features case histories, detailing actual events that include aspects of how the contamination occurred and its effects on wildlife Provides material from a wide variety of international sources

Book Description
Historically, regulations governing chemical use have often focused on widely used chemicals and acute human health effects of exposure to them, as well as their potential to cause cancer and other adverse health effects. As scientific knowledge has expanded there has been an increased awareness of the mechanisms through which chemicals may exert harmful effects on human health, as well as their effects on other species and ecosystems. Identification of high-priority chemicals and other chemicals of concern has prompted a growing number of state and local governments, as well as major companies, to take steps beyond existing hazardous chemical federal legislation. Interest in approaches and policies that ensure that any new substances substituted for chemicals of concern are assessed as carefully and thoroughly as possible has also burgeoned. The overarching goal of these approaches is to avoid regrettable substitutions, which occur when a toxic chemical is replaced by another chemical that later proved unsuitable because of persistence, bioaccumulation, toxicity, or other concerns. Chemical alternative assessments are tools designed to facilitate consideration of these factors to assist stakeholders in identifying chemicals that may have the greatest likelihood of harm to human and ecological health, and to provide guidance on how the industry may develop and adopt safer alternatives. A Framework to Guide Selection of Chemical Alternatives develops and demonstrates a decision framework for evaluating potentially safer substitute chemicals as primarily determined by human health and ecological risks. This new framework is informed by previous efforts by regulatory agencies, academic institutions, and others to develop alternative assessment frameworks that could be operationalized. In addition to hazard assessments, the framework incorporates steps for life-cycle thinking - which considers possible impacts of a chemical at all stages including production, use, and disposal - as well as steps for performance and economic assessments. The report also highlights how modern information sources such as computational modeling can supplement traditional toxicology data in the assessment process. This new framework allows the evaluation of the full range of benefits and shortcomings of substitutes, and examination of tradeoffs between these risks and factors such as product functionality, product efficacy, process safety, and resource use. Through case studies, this report demonstrates how different users in contrasting decision contexts with diverse priorities can apply the framework. This report will be an essential resource to the chemical industry, environmentalists, ecologists, and state and local governments.
