Book Description
This edited volume collects population and metapopulation models for a wide variety of species, focusing on the use of models in population-level risk assessment for toxins. Each chapter of Demographic Toxicity describes the application of a population model to one species, with the aim of demonstrating how various life history characteristics of the species are incorporated into the model, how ecotoxicological impacts are modeled, and how the results of the model has been or can be used in risk assessment. The model in each chapter is implemented in RAMAS software, which uses matrix modeling of population dynamics. RAMAS software is believed to be the most powerful tool ever invented for this task.Demographic Toxicity includes a CD that contains a demo version of the program and the data files for each species. The book explains how to use these specific tools for modeling, analysis, and interpretation of data. Demographic Toxicity provides a major review of current knowledge on population dynamics in different species, representing both terrestrial and aquatic environments.

Book Description
Demography in Ecotoxicology focuses on the interface between toxicology, life history and demographic theory. This comprehensive book examines the different ways of adequately assessing the potential impact of toxic stress on populations and discusses how to obtain an insight into the underlying physiological and genetic mechanisms. The theory is illustrated with empiricial observations on a number of species and organisational levels and the book incorporates: * case studies; * real data; * life history models; * methodologies; and, * recommendations for risk assessment Written by an international team of researchers, Demography in Ecotoxicology will be invaluable to ecotoxicologists, ecologists and wildlife conservationists in academia, industry and regulatory bodies wishing to gain a greater understanding into the prediction and effects of natural and man-made toxicants on populations.

Intentional Human Dosing Studies for EPA Regulatory Purposes

Book Description
The EPA commissioned The National Academies to provide advice on the vexing question of whether and, if so, under what circumstances EPA should accept and consider intentional human dosing studies conducted by companies or other sources outside the agency (so-called third parties) to gather evidence relating to the risks of a chemical or the conditions under which exposure to it could be judged safe. This report recommends that such studies be conducted and used for regulatory purposes only if all of several strict conditions are met, including the following: The study is necessary and scientifically valid, meaning that it addresses an important regulatory question that can't be answered with animal studies or nondosing human studies; The societal benefits of the study outweigh any anticipated risks to participants. At no time, even when benefits beyond improved regulation exist, can a human dosing study be justified that is anticipated to cause lasting harm to study participants; and All recognized ethical standards and procedures for protecting the interests of study participants are observed. In addition, EPA should establish a Human Studies Review Board (HSRB) to evaluate all human dosing studiesâ€"both at the beginning and upon completion of the experimentsâ€"if they are carried out with the intent of affecting the agency's policy-making.

Book Description
Ecological Toxicity Testing provides a critical comparison of toxicity tests at different levels of biological organization from cells to landscapes. While ecological toxicity tests can be designed at any of the many levels of complexity and on spatial scales ranging from square millimeters to square kilometers, the uses to which this information can be put often differs with scale. In the past decade, tests at all levels have been refined and subjected to critical evaluations of their predictive accuracy. This text/reference includes evaluations of toxicity test systems at various scales and complexities by expert practitioners. It also offers broader analyses of the effects of scale on endpoint selection, test design and analyses, and chemical sensitivity.

Book Description
Ecological Impacts of Toxic Chemicals presents a comprehensive, yet readable account of the known disturbances caused by all kinds of toxic chemicals on both aquatic and terrestrial ecosystems. Topics cover the sources of toxicants, their fate and distribution through the planet, their impacts on specific ecosystems, and their remediation by natural systems. Each chapter is written by well-known specialists in those areas, for the general public, students, and even scientists from outside this field. The book intends to raise awareness of the dangers of chemical pollution in a world dominated by industry and globalization of resources. Because the problems are widespread and far reaching, it is hoped that confronting the facts may prompt better management practices at industrial, agricultural and all levels of management, from local to governmental, so as to reduce the negative impacts of chemical contaminants on our planet.
