Selenium can be beneficial but it can also be toxic, particularly to egg-laying vertebrates (fish, birds, amphibians, reptiles). Concentrations of selenium in the environment are increasing globally as a result of mining, power generation, agriculture, and animal husbandry. Population-level effects from selenium in natural ecosystems have been definitively documented in three freshwater lakes and reservoirs and are suspected elsewhere in both freshwater and estuarine environments. Ecological Assessment of Selenium in the Aquatic Environment summarizes the state-of-the-science and provides globally applicable guidance for assessing and managing the environmental effects of selenium. This book is based on the deliberations of a multidisciplinary and international group of scientists, managers, and policymakers. Ecological Assessment of Selenium in the Aquatic Environment is one of many SETAC publications that offer timely reviews and new perspectives on current topics relating to broad environmental toxicology and chemistry issues. SETAC publications are based on collaborative efforts of top scientists, managers and policy makers, and they undergo extensive pre-publication reviews. SETAC assumes an active leadership role in advancing key scientific issues and publishes the peer-reviewed, international journals, Environmental Toxicology and Chemistry and Integrated Environmental Assessment and Management.
