Download or read book Contaminated Water Supplies at Camp Lejeune written by National Research Council and published by National Academies Press. This book was released on 2009-09-06 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early 1980s, two water-supply systems on the Marine Corps Base Camp Lejeune in North Carolina were found to be contaminated with the industrial solvents trichloroethylene (TCE) and perchloroethylene (PCE). The water systems were supplied by the Tarawa Terrace and Hadnot Point watertreatment plants, which served enlisted-family housing, barracks for unmarried service personnel, base administrative offices, schools, and recreational areas. The Hadnot Point water system also served the base hospital and an industrial area and supplied water to housing on the Holcomb Boulevard water system (full-time until 1972 and periodically thereafter). This book examines what is known about the contamination of the water supplies at Camp Lejeune and whether the contamination can be linked to any adverse health outcomes in former residents and workers at the base.

Download or read book Biomonitoring of Trace Aquatic Contaminants written by David J.H. Phillips and published by Springer Science & Business Media. This book was released on 2013-03-12 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Twenty years ago, researchers wishing to identify contaminated areas in aquatic environments generally took water samples, and analysed them badly (as we have since discovered) for a few "pollutants" which were of topical note at the time (and which could be quantified by the methods then available). Today, the use of aquatic organisms as biomonitors in preference to water analysis has become commonplace, and many national and interna tional programmes exist around the world involving such studies. We believe that this trend will continue, and have complete faith in the methodology (when it is employed correctly). We hope that the following text assists in some part in attaining this goal, such that the quality of our most basic global resource -water - is adequately protected in the future. DAVE PHILLIPS, PHIL RAINBOW England, March 1992 vii Acknowledgements Our thanks for contributions to this book are due to several individuals and groups, for varying reasons. Firstly, a co-authored book is always a triumph, and we trust that the following text is an acceptable compromise of the views of two individual authors, on a complex and developing topic. Secondly, many of the ideas herein have crystallised over the last two decades as the field has grown, and we are individually and collectively grateful to a number of researchers for their insight and assistance.

This book was released on 2008-01-10 with total page 1200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface contamination is of cardinal importance in a host of technologies and industries, ranging from microelectronics to optics to automotive to biomedical. Thus, the need to understand the causes of surface contamination and their removal is very patent. Generally speaking, there are two broad categories of surface contaminants: film-type and particulates. In the world of shrinking dimensions, such as the ever-decreasing size of microelectronic devices, there is an intensified need to understand the behavior of nanoscale particles and to devise ways to remove them to an acceptable level. Particles which were functionally innocuous a few years ago are ôkiller defectsö today, with serious implications for yield and reliability of the components. This book addresses the sources, detection, characterization and removal of both kinds of contaminants, as well as ways to prevent surfaces from being contaminated. A number of techniques to monitor the level of cleanliness are also discussed. Special emphasis is placed on the behaviour of nanoscale particles. The book is amply referenced and profusely illustrated. • Excellent reference for a host of technologies and industries ranging from microelectronics to optics to automotive to biomedical. • A single source document addressing everything from the sources of contamination to their removal and prevention. • Amply referenced and profusely illustrated.

Available in PDF, EPUB and Kindle. Book excerpt: The trajectories of pollution in global capitalism, from the toxic waste of early tanneries to the poisonous effects of pesticides in the twentieth century. Through the centuries, the march of economic progress has been accompanied by the spread of industrial pollution. As our capacities for production and our aptitude for consumption have increased, so have their byproducts--chemical contamination from fertilizers and pesticides, diesel emissions, oil spills, a vast "plastic continent" found floating in the ocean. The Contamination of the Earth offers a social and political history of industrial pollution, mapping its trajectories over three centuries, from the toxic wastes of early tanneries to the fossil fuel energy regime of the twentieth century.

Download or read book Trace Metals and Infectious Diseases written by Jerome O. Nriagu and published by MIT Press. This book was released on 2024-06-11 with total page 501 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experts explore the influence of trace metals on the pathogenesis of infectious diseases. Many parts of the world in which common infectious diseases are endemic also have the highest prevalence of trace metal deficiencies or rising rates of trace metal pollution. Infectious diseases can increase human susceptibility to adverse effects of metal exposure (at suboptimal or toxic levels), and metal excess or deficiency can increase the incidence or severity of infectious diseases. The co-clustering of major infectious diseases with trace metal deficiency or toxicity has created a complex web of interactions with serious but poorly understood health repercussions, yet has been largely overlooked in animal and human studies. This book focuses on the distribution, trafficking, fate, and effects of trace metals in biological systems. Its goal is to enhance our understanding of the relationships between homeostatic mechanisms of trace metals and the pathogenesis of infectious diseases. Drawing on expertise from a range of fields, the book offers a comprehensive review of current knowledge on vertebrate metal-withholding mechanisms and the strategies employed by different microbes to avoid starvation (or poisoning). Chapters summarize current, state-of-the-art techniques for investigating pathogen-metal interactions and highlight open question to guide future research. The book makes clear that improving knowledge in this area will be instrumental to the development of novel therapeutic measures against infectious diseases. Contributors M.

Download or read book Review of Contamination Problems in Measuring Trace Elements Revue Des Problemes de Contamination Dans Le Dosage Des Traces written by M. Pinta and published by . This book was released on 1973 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every sample analyzed must reflect the makeup of the environment in its natural state; contamination hazards, particularly in relation to trace measurements, range from the taking of the sample to the physical or chemical measurement of the content of the particular element being sought. The sources of contamination are many, sometimes built-in or accidental, but nevertheless frequently overlooked. The effects of this on trace measurements are analyzed one by one, and an effort is made to calculate the resulting error; insofar as possible, the best remedy for the situation is suggested. The following factors are studied: sampling, bagging, transport; physical treatment: parting, griding sifting; chemical treatment: acid or alkaline attack, solution; the influence of glassware, equipment, reagents, exposure to air, and handling by personnel. Ordinary practical examples are given to illustrate these sources of error. The main ways of measuring trace elements are reviewed, and the contamination hazards inherent in each are cited.
