This book was released on 2006-01-12 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: The science of ecotoxicology and the practice of ecological risk assessment are evolving rapidly. Ecotoxicology as a subject area came into prominence in the 1960s after the publication of Rachel Carson's book on the impact of pesticides on the environment. The rise of public and scientific concern for the effects of chemical pollutants on the environment in the 1960s and 1970s led to the development of the discipline of ecotoxicology, a science that takes into account the effects of chemicals in the context of ecology. Until the early 1980s, in spite of public concern and interest among scientists, the assessment of ecological risks associated with natural or synthetic pollutants was not considered a priority issue by most government. However, as the years passed, a better understanding of the importance of ecotoxicology emerged and with it, in some countries, the progressive formalization of an ecological risk assessment process. Ecological risk assessment is a conceptual tool for organizing and analyzing data and information to evaluate the likelihood that one or more stressors are causing or will cause adverse ecological effects. Ecological risk assessment allows risk managers to consider available scientific information when selecting a course of action, in addition to other factors that may affect their decision (e. g. , social, legal, political, or economic). Ecological risk assessment includes three phases (problem formulation, analysis, and risk characterization).

Download or read book Ecological Assessment of Aquatic Resources written by Michael T. Barbour and published by Setac Press. This book was released on 2004 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: With a goal of introducing science into the decision-making process, 60 individuals representing government, industry, academia, and nongovernmental organisations from eight different countries participated in a Society of Environmental Toxicology and Chemistry (SETAC) Pellston Workshop to address the relationship between ecological assessment and ecological risk assessment and their role in aquatic resources. A result of this workshop, this book presents guidelines for effectively conducting and communicating ecological assessments. Through successful integration of economic, social, and behavioural perspectives and approaches, ecological assessments can ultimately produce sound decisions to protect and manage our aquatic resources.

Download or read book Amphibian Decline written by Greg Linder and published by Setac Press. This book was released on 2003 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines the ecotoxicology and stressors of amphibians in an attempt to address issues related to declining amphibian populations and the role that various stressors might have in those losses. It identifies gaps in current data, interprets information into an existing framework, and points toward critical areas for future research. Through the combined efforts of research and resource management communities, recommendations can be developed to change current policies and management actions to address the problem of amphibian decline.
