In modern sediment research on contaminants five aspects are discussed which, in an overlapping succession, also reflect develop ment of knowledge on particle-associated pollutants during the past twenty-five years: (1) identification of sources and their distribution; (2) evaluation of solid/solution relations; (3) study of transfer mecha nisms to biological systems; (4) assessment of environment impact; and (5) selection and further development of remedial measures, in par ticular, of dredged materials. Scientific research and practical develop ment are still expanding in all these individual aspects. Similar to other waste materials, management of contaminated sed iments requires a holistic approach. This means that assessment of biogeochemical reactions, interfacial processes and transfer mecha nisms as well as the prognosis of long-term borderline conditions, in particular of capacity-controlling properties, should be an integrated part of the wider management scheme, i.e., the analytical and experi mental parameters should always be related to potential remediation options for a specific sediment problem. The underlying coordinated project, which was funded by the German Federal Ministry for Science and Technology (now the Federal Ministry for Education, Science, Research and Technology) provided excellent opportunities for multidisciplinary effort, bringing together biologists, chemists, engineers, geologists and other researchers. During its active phase, the group attracted much interest nationally and internationally. The group members highly appreciate the manifold contacts and invitations during the past five years.

Modeling the Fate and Effect of the Toxic Substances in the Environment contains the proceedings of a Symposium on "Modeling the Fate and Effect of Toxic Substances in the Environment", held on June 6-10, 1983 in Copenhagen, Denmark, and sponsored by the International Society for Ecological Modeling. The symposium provided a forum for discussing the state of the art in modeling the fate and effect of toxic substances in the environment. Topics include parameter estimation, theoretical considerations, and models of a wide variety of toxic compounds in aquatic and terrestrial ecosystems. Comprised of 16 chapters, this volume begins with an account of parameter estimation in toxic substance models, followed by a discussion on extinction and persistence in models of population-toxicant interactions. The reader is then introduced to PATHWAY, a simulation model of the transport of radionuclides through agroecosystems. Subsequent chapters focus on possible cause-effect relationships in the dying of Germany's spruce-fir forests; application of risk and uncertainty analysis techniques to a heavy metal speciation model; the biological effects of toxicants in aquatic microcosm systems; and the dispersal and biological effect of toxins in the Tamar estuary in England. The book concludes with a description of a nonlinear mathematical model for the transport and spreading of oil slicks. This book will be useful to students, practitioners, and researchers in the field of inorganic chemistry, as well as those who are interested in the environmental effects of toxic compounds.

Environmental Toxicology and Human Health is a component of Encyclopedia of Environmental and Ecological Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Toxicology is the study of harmful effects of chemicals on biological systems. Humans, animals, and plants are increasingly being exposed to chemicals in the environment. The ever-increasing use of chemicals in industries has also resulted in further pollution of the environment. As toxic chemicals are widespread in the environment, there is a potential for these chemicals to cause significant damage and harmful effects on human health. The volume on Environmental Toxicology and Human Health discusses matters of great relevance to our world such as: Environmental Toxicology and Human Health; Health Effects from Exposure to Acute Levels of Industrial Chemicals; Health Effects from Exposure to Chronic Levels of Industrial Chemicals; Control Strategies; Pediatric Lead Poisoning of Residential Origin; Insecticides; Herbicides; Rodenticides; Virus-Induced Diseases; Fungus and Actinomycete-Induced Diseases; Sportfish Consumption: Socio-Cultural and Economic Aspects, Ethnicity and Effectiveness of Health Advisories; Impact of Socioeconomic Factors on Residential Indoor Air Quality and Human Health; Social Concerns for Environmental Exposures to Toxic Substances; Environmental Justice as a Component of Environmental Decision-Making; Minamata Disease in Japan; Mercury-Contaminated Grain in Iraq; Case Study of Air Pollution Episodes in Meuse Valley of Belgium, Donora of Pennsylvania, and London, U.K.; Case Study of the Bhopal Incident; Case Study of Lyme Disease; Case History: Ebola Hemorrhagic Fever in Zaire, 1995; Case Studies of Anthrax Outbreaks; Case Study of Health Effects of Cryptosporidium in Drinking Water . These two volumes are aimed at the following five major target audiences: University and College Students Educators, Professional Practitioners, Research Personnel and Policy Analysts, Managers, and Decision Makers, NGOs and GOs.

Pollutants, Human Health and the Environment is a comprehensive, up-to-date overview of environmental pollutants that are of current concern to human health. Clearly structured throughout, the main body of the book is divided by pollutant type with a chapter devoted to each group of pollutants. Each chapter follows a similar format to facilitate comparison and discussion. For each pollutant, the authors describe the sources, pathways, environmental fate and sinks as well as known toxicological effects. Importantly, the second chapter on heavy metals and other inorganic substances deals with trace element deficiencies which can have serious problems for human health. Some rocks and soils are naturally low in some trace elements and intensive agriculture over the past half century has effectively mined many trace elements reducing their levels in soils and crops. The final chapter is a discussion about the various risk assessment frameworks and regulations covering the main pollutants. Comprehensive, up-to-date coverage of environmental pollutants of concern to human health Clearly divided into pollutant type with each chapter devoted to a different pollutant group Clearly structured throughout with the same format for each chapter to help facilitate comparison and discussion and enable readers to prioritise chemicals of concern Description of the sources, pathways, environmental fate and known toxicological effect Includes contributions from leading researchers and edited by a team of experts in the field

In response to a congressional mandate, this book examines whether knowing the amounts of toxic substances entering and leaving manufacturing facilities is useful in evaluating chemical releases to the environment, waste reduction progress, and chemical management practices. Tracking of these substances with rigorous engineering data is compared with a less resource-intensive alternative to determine the feasibility and potential usefulness to the public and the government.

Everyday exposures to common chemicals found in homes, schools, and workplaces are having devastating long-term and inter-generational consequences on human health. At the same time, the risks associated with these exposures (and the burdens of managing them) rest disproportionately on the shoulders of women. Written by leading researchers in science, law, and public policy, the chapters in Our Chemical Selves critically examine the system that manufactures the chemicals as well as the social, political, and gender relations that enable harmful chemicals to continue being produced and consumed. This book demonstrates the urgent need to revise existing approaches to the regulation of toxic substances in Canada.

This is a print on demand edition of a hard to find publication. The EPA is authorized under the Toxic Substances Control Act (TSCA) to obtain information on the risks of chemicals and to control those that it determines to pose an unreasonable risk. EPA also conducts assessments of chemicals under its Integrated Risk Information System (IRIS) program. Nonetheless, EPA does not have sufficient information to determine whether it should establish controls to limit public exposure to many chemicals that may pose substantial health risks. This testimony addresses EPA's implementation of TSCA and IRIS and options for: (1) obtaining more information on chemical risks; (2) controlling these risks; and (3) sharing more of the information collected under TSCA.
