Book Synopsis Evaluating Endocrine Disruption in Receiving Waters by : P. V. Cline
Download or read book Evaluating Endocrine Disruption in Receiving Waters written by P. V. Cline and published by IWA Publishing. This book was released on 2003-01-01 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, concerns have been raised that low concentrations of chemicals may alter the normal functions of the endocrine system, resulting in potentially significant adverse effects on growth, reproduction, and/or development. For domestic wastewater discharges to surface water bodies, estrogenic activity of effluents has been suggested by chemical analysis, biomarkers, and /or in vitro assays. Chemical Measurements. Using sensitive analytical techniques, natural or synthetic hormones and chemicals that mimic estrogen, have been detected in some domestic wastewater effluents and associated watersheds at low concentrations. Biomarkers. Several studies have demonstrated physiological changes in fish that may be attributed to exposure to estrogenic compounds. These include the presence of vitellogenin protein in male fish and/or intersex conditions. In vitro assays. The Yeast Estrogen Screen (YES) has been used to characterize estrogenicity of effluents, influents, biosolids and surface waters. This two-year WERF project explored approaches to evaluate the potential for biomarker formation as a result of effluent exposures, and the subsequent relevance of the emerging assays and physiological measurements on potential adverse impacts to individuals or populations of fish in the receiving streams. The endocrine system is complex, and many factors can influence the physiological measurements, including methods, sex, age, reproductive status, seasonal and circadian rhythms, diet, temperature, etc. and produce transient changes in physiology but no significant effect on the individual.

This book was released on 2002-03-05 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Geological Survey (USGS) established the National Water Quality Assesment (NAWQA) program in 1985 to assess water quality conditions and trends in representative river basins and aquifers across the United States. With this report, the NRC's Water Science and Technology Board has provided advice to USGS regarding NAWQA five separate times as the program evolved from an unfunded concept to a mature and nationally-recognized program in 2002. This report assesses the program's development and representative accomplishments to date and makes recommendations on opportunities to improve NAWQA as it begins its second decade of nationwide monitoring.
