Download or read book Biological Monitoring in Water Pollution written by John E. Cairns and published by Elsevier. This book was released on 2017-05-03 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological Monitoring in Water Pollution focuses on the processes, methodologies, and experiments involved in monitoring water pollution. Divided into six parts, the selection features the contributions of authors who have devoted time and energy in advancing biological monitoring to measure pollution in water. The first part is a review paper that focuses on the strengths of biological monitoring relative to the detection of harmful conditions. This part stresses that biological monitoring has received considerable attention. The second part deals with review papers on biological monitoring. The discussions focused on the identification of problem; the review of functional methods; community and ecosystem indices used in biomonitoring; and structure and function relationships relative to ecosystem stress. The third part covers the application of community structural analysis to biomonitoring programs. This part puts emphasis on the need to develop methods to identify community structures relative to the conduct of ecological research. Other parts of the selection are devoted to toxicity testing and discussions on the monitoring of waste discharges and introduction of chemicals to the environment. Experiments and models are presented to support the claims of the authors. The book can be a valuable source of information for those interested in the monitoring of water pollution.

Download or read book Ecotoxicology Problems and Approaches written by Simon A. Levin and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecotoxicology is the science that seeks to predict the impacts of chemi cals upon ecosystems. This involves describing and predicting ecological changes ensuing from a variety of human activities that involve release of xenobiotic and other chemicals to the environment. A fundamental principle of ecotoxicology is embodied in the notion of change. Ecosystems themselves are constantly changing due to natural processes, and it is a challenge to distinguish the effects of anthropogenic activities against this background of fluctuations in the natural world. With the frustratingly large, diverse, and ever-emerging sphere of envi ronmental problems that ecotoxicology must address, the approaches to individual problems also must vary. In part, as a consequence, there is no established protocol for application of the science to environmental prob lem-solving. The conceptual and methodological bases for ecotoxicology are, how ever, in their infancy, and thus still growing with new experiences. In deed, the only robust generalization for research on different ecosystems and different chemical stresses seems to be a recognition of the necessity of an ecosystem perspective as focus for assessment. This ecosystem basis for ecotoxicology was the major theme of a previous pUblication by the Ecosystems Research Center at Cornell University, a special issue of Environmental Management (Levin et al. 1984). With that effort, we also recognized an additional necessity: there should be a continued develop ment of methods and expanded recognition of issues for ecotoxicology and for the associated endeavor of environmental management.

Download or read book Controlling Chemical Hazards written by R.P. Cote and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents environmental protection managers and advanced students in environmental studies programs with an overview of the principles, facts, multidisciplinary approaches, and some of the complex ities of the management of toxic substances. The text explores critical issues facing managers responsible for prevent ing and controlling problems associated with the manufacture,. transport, storage, use and disposal of chemicals. It does this from two perspectives. The first is a disciplinary perspective, that is environmental chemistry, of toxicology, engineering, economics, sociology and political science, all which playa role in implementing comprehensive programs to manage chemicals. The second perspective is from the view of industry, govern ment, academia and non-government organizations. For example, Chapter 5 is authored by technical managers of a major chemical company, Chap ters 6 and 12 by government scientists and managers respectively, and Chapter 10 by a respected member of the environmental lobby. An appreciation of these perspectives is very important for developing and running effective chemical management programs.

Download or read book Endocrine Disrupters and Carcinogenic Risk Assessment written by Lech Chyczewski and published by IOS Press. This book was released on 2002 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work is devoted to the study of the endocrine-related effects on human health with special reference to carcinogenesis, and to the assessment of carcinogenic risk. After providing basic information at the general, cellular and molecular levels, the contents focus on the paradigm of biologically-based risk assessment, as developed form physiologically-based toxicokinetic models. The analysis of this material is proposed as the novel parameters for developing biologically-based models of carcinogenesis, considered to be more relevant to risk assessment than traditional approaches.
