This book was released on 1996 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: A methanogenic-methanotrophic system has been established to assess the capability of sequential treatment to transform the chlorinated aliphatics perchloroethylene (PCE), carbon tetrachloride (CT) and 1,1,1-trichloroethane (1, 1,1-TCA). Experiments compared the transformation of PCE alone and in a mixture of the target compounds. A comparison of acetate and iron as electron donors was also made. Data from the anaerobic systems have shown that PCE transformation is inhibited when in a mixture with CT and 1,1,1-TCA compared to when it is fed alone. When iron is the electron donor, PCE and 1,1,1-TCA are transformed without an acclimation period. CT was completely transformed regardless of the electron donor used. The acetate-fed system required approximately 60 days to acclimate to 1,1,1-TCA and 70 days for acclimation to PCE. Although the sequential system has been constructed, sampling from the aerobic column was not done before the thesis project ended. More investigation is required to determine the ability of the sequential system to degrade PCE, CT, and 1,1,1- TCA.

This book was released on 2000 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Risk assessments for chlorinated solvents are typically only done for single chemicals, and clean up costs are based on these assessments. However, groundwater and drinking water supplies are usually contaminated with multiple compounds. The most commonly used approach for assessing risks to multiple chemical exposures assumes additivity of response. This study investigates the effect of exposure to mixtures of carbon tetrachloride and 2 other chlorinated solvents, perchloroethylene and 1,1,1,2-tetrachloroethane. Metabolite formation, which is the process thought to be responsible for toxicity is affect carbon tetrachloride. By understanding the alteration in metabolic outcome for perchlorethylene and 1,1,1,2-tetrachloroethane the assessment of risk associated with exposures to these types of mixtures may be more science-based.

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.

This book was released on 2012-12-06 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended for anyone who cares about the health of people exposed to industrial pollutants. Attention is given to those pollutants which present a possible risk to the genetic material of exposed workers. Chapters are devoted to heavy metals such as arsenic, beryllium, cadmium, chromium, lead, mercury, nickel, etc.; insecticides (chlorinated, organophosphorus, and carbonate insecticides); monomers such as vinyl-chloride, acrylonitrile, styrene, vinylidene chloride, butadiene, chlorobutadiene, hexachlorobuta diene, etc.; and halogenated hydrocarbon solvents such as chloroform, carbon tetrachloride, trichloroethylene, I, 2-dichloroethane, tetrachloroethyl ene, dichloromethane, and I, I, I-trichloroethane. The main aim of this work is to provide the physician, the biologist, the pharmacologist, or anyone involved in genetic toxicology with a useful compendium of up-to-date information and references. Efforts are made to open the field to nonspecialists. An introductory chapter deals with the mechanisms whereby a given compound, reaching genetic material, either directly or indirectly, may increase the risk of a cancer developing in the exposed individual and of abnormalities being passed on to his or her progeny. Efforts are also made to allow easy and efficient reading for those who are not interested in detailed results. Comparative tables provide the following data on the compounds studied: chemical properties, production, occurrence, accepted standards in the industry, and positive or negative results with different test systems. Finally, senior research workers might find good descriptions in this book of the most recent results from mutagenesis and carcinogenesis testing in plant, nonmammalian, and mammalian systems.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents WHO guidelines for the protection of public health from risks due to a number of chemicals commonly present in indoor air. The substances considered in this review, i.e. benzene, carbon monoxide, formaldehyde, naphthalene, nitrogen dioxide, polycyclic aromatic hydrocarbons (especially benzo[a]pyrene), radon, trichloroethylene and tetrachloroethylene, have indoor sources, are known in respect of their hazardousness to health and are often found indoors in concentrations of health concern. The guidelines are targeted at public health professionals involved in preventing health risks of environmental exposures, as well as specialists and authorities involved in the design and use of buildings, indoor materials and products. They provide a scientific basis for legally enforceable standards.
Download or read book Dehalogenation written by Max M. Häggblom and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 702 pages. Available in PDF, EPUB and Kindle. Book excerpt: Halogenated organic compounds constitute one of the largest groups of environmental chemicals. The industrial production of new halogenated organic compounds has increased throughout the last century peaking in the 1960s, and continuing in widespread use today. Organohalides are integral to a variety of industrial applications, including use as solvents, degreasing agents, biocides, pharmaceuticals, plasticizers, hydraulic and heat transfer fluids, and intermediates for chemical synthesis, to name a few. It is important to recognize the beneficial aspects of halogenated organic compounds, as well as their potentially deleterious impact on the environment and health. Recognition ofthe adverse environmental effects ofmanytypes oforganohalide compounds has led to efforts to reduce or eliminate the most problematic ones. Although organohalide compounds are typically considered to be anthropogenic industrial compounds, they have their counterpart in several thousands of natural biogenic and geogenic organohalides, representing most classes of organic chemicals. Natural sources account for a significant portion of the global organohalogen budget. This volume authored by recognized experts in the field provides a current perspective on how both natural and synthetic organohalides are formed and degraded, and how these processes are incorporated into a global halogen cycle. The focus is on microbial processes, since these play a major role both in the production and degradation, i. e. , cycling of halogenated organic compounds inthe environment. This book is organized into five parts. Part I, Introduction, provides a global perspective on the issues of organohalides and their fate in the environment.
