This book was released on 2005-05-18 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Perchlorateâ€"a powerful oxidant used in solid rocket fuels by the military and aerospace industryâ€"has been detected in public drinking water supplies of over 11 million people at concentrations of at least 4 parts per billion (ppb). High doses of perchlorate can decrease thyroid hormone production by inhibiting the uptake of iodide by the thyroid. Thyroid hormones are critical for normal growth and development of the central nervous system of fetuses and infants. This report evaluates the potential health effects of perchlorate and the scientific underpinnings of the 2002 draft risk assessment issued by the U.S. Environmental Protection Agency (EPA). The report finds that the body can compensate for iodide deficiency, and that iodide uptake would likely have to be reduced by at least 75% for months or longer for adverse health effects, such as hypothryroidism, to occur. The report recommends using clinical studies of iodide uptake in humans as the basis for determining a reference dose rather than using studies of adverse health effects in rats that serve as EPA's basis. The report suggests that daily ingestion of 0.0007 milligrams of perchlorate per kilograms of body weightâ€"an amount more than 20 times the reference dose proposed by EPAâ€"should not threaten the health of even the most sensitive populations.

Download or read book Perchlorate in the Environment written by Edward Todd Urbansky and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a symposium sponsored by the Environmental Division of the American Chemical Society, Perchlorate in the Environment is the first comprehensive book to address perchlorate as a potable water contaminant. The two main topics are: analytical chemistry (focusing on ion chromatography and electrospray ionization mass spectrometry), and treatment or remediation. Also included are topics such as ion exchange, phytoremediation, bacterial reduction of perchlorate, bioreactors, and in situ bioremediation. To provide complete coverage, background chapters on fundamental chemistry, toxicology, and reulatory issues are also included. The authors are environmental consultants, government researchers, industry experts, and university professors from a wide array of disciplines.

Download or read book Ecotoxicology Ecological Risk Assessment and Multiple Stressors written by Gerassimos Arapis and published by Springer Science & Business Media. This book was released on 2006-02-09 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 Perchlorates written by Lawrence E. Matthews and published by Nova Science Publishers. This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Perchlorates are the salts derived from perchloric acid (HClO4). They occur both naturally and through manufacturing. They have been used as a medicine for more than 50 years to treat thyroid gland disorders and are used extensively within the pyrotechnics industry, and ammonium perchlorate is also a component of solid rocket fuel. This book presents current research data from across the globe in the study of perchlorates, their production, uses, and health effects. Some topics discussed, herein, are: trends in the study of the electrochemical stability of perchlorate ions; the structural and vibrational properties of chromyl perchlorate; perchlorate formation in electrochemical water disinfection; metal perchlorates as Lewis acids; alkaline earth metal perchlorates; and removal of perchlorate from water.
