Available in PDF, EPUB and Kindle. Book excerpt: This book provides up-to-date information on chlorinated organics in the environment that can be used in monitoring, impact assessment, and decision-making processes. The text assists readers in predicting the potential for organic contamination as well as the critical medium of exposure to the health of the ecosystem and humans. Toxicity profiles provided for each chemical allow for evaluation of the short- and long-term effects on the environment. Discussions of environmental residues and pertinent worldwide regulations help readers compare chloroorganic contamination in different areas and analyze the associated regulatory approaches. Chlorinated Organic Compounds in the Environment begins with an introduction to chlorinated organic compounds and discussions of fate processes and environmental migration, based on their physical properties and processes. Next, the text focuses on chlorinated aliphatic hydrocarbons; chlorinated aromatic hydrocarbons-monocyclic and polycyclic compounds; and chlorinated biocides, phenols, dioxins, and furans in the environment. The North American and International regulations and advisories in the management of chlorinated organic compounds are reviewed in Chapters 3-8. The last two chapters of the book deal with prioritization for regulatory and monitoring assessment and regulatory decision-making processes. A glossary and comprehensive subject index makes terms easy to understand and find throughout the text. Environmental managers, regulatory personnel, scientists, and students will gain a broader understanding of environmental problems and how they can be applied to different disciplines such as chemistry, life sciences, and engineering with this important reference.

Download or read book Halogenated Biphenyls Terphenyls Naphthalenes Dibenzodioxins and Related Products written by R.D. Kimbrough and published by Elsevier. This book was released on 2012-12-02 with total page 535 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chemical industry is increasingly faced with problems arizing from chemicals produced during the manufacture of halogenated biphenyls or phenols. Knowledge of these chemicals and their destructive properties is sporadic, and the acute toxicity of this group varies widely. This informative revised edition presents the chemistry, environmental pollution problems, animal toxicology and information about structure-activity relationships. A brief overview is given of worker exposure and occupational illness. The book is divided into three parts: chemistry and environmental contamination; experimental toxicology; and human exposure and effects. Because of the great deal of interest in these compounds much new research work has been conducted since the first edition of this book was published. This revised edition has retained the effectiveness and clarity of the first edition, while being supplemented with new information, condensed old information, and examples of recent incidents.

Download or read book QSAR in Environmental Toxicology written by K.L. Kaiser and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ever since Rachel Carson's Silent Spring, we have generally become aware of environmental contaminants and their effects on the ecosystem. The findin~ of PCB's in fish by Soren Jensen in Sweden, the recognition of mirex as contaminant in fish from Lake Ontario, and the discoveries of contaminant laden leachates from dumpsites such as the Love Canal have become milestones in the search for and charac terization of contaminants in our environment. At this time, the problem no longer is so much the identifi cation of contaminants and their sources. Rather, we are now faced with solving questions on the fates and effects of such compounds. This includes the search for mechanisms to deal effectively with the large number of chemicals already found in water, air and biota. One of such time and cost saving scientific avenues is the field of quantitative structure-activity correlations for the prediction of the environmental behavior and effects of compounds.

Download or read book Handbook on Biodegradation and Biological Treatment of Hazardous Organic Compounds written by M.H. van Agteren and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: The introduction of synthetic organic chemicals into the environment during the last few decades has given rise to major concern about the ecotoxicological effects and ultimate fate of these compounds. The pollutants that are considered to be most hazardous because of their intrinsic toxicity, high exposure level, or recalcitrant behavior in the environment have been placed on blacklists and other policy priority lists. The fate of synthetic compounds that enter the environment is mainly determined by their rate of biodegradation, which therefore also has a major effect on the degree of bioaccumulation and the risk of ecotoxicological effects. The degree and rate of biodegradation is also of critical importance for the feasibility of biological techniques to clean up contaminated sites and waste streams. The biodegradation of xenobiotics has thus been the subject of numerous studies, which resulted in thousands of publications in scientific journals, books, and conference proceedings. These studies led to a deeper understanding of the diversity of biodegradation processes. As a result, it has become possible to enhance the rate of degradation of recalcitrant pollutants during biological treatment and to design completely new treatment processes. At present, much work is being done to expand the range of pollutants to which biodegradation can be applied, and to make treatment techniques less expensive and better applicable for waste streams which are difficult to handle.

Download or read book Microbe Induced Degradation of Pesticides written by Shree Nath Singh and published by Springer. This book was released on 2016-09-12 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the microbial degradation of endosulfan, lindane, chlorophenols, organochlorine, aldrin, dieldrin, isoproturon and atrazine, etc. which are commonly used in crop fields to kill the pests. Further, it illustrates the role of degradative enzymes, metabolic pathways of degradation, toxicity of metabolites, and the factors regulating the pesticide degradation. In view of persistence of synthetic pesticides, scientists have discovered suitable microbes, such as bacteria, fungi and algae (naturally occurring or genetically engineered) over the years. After successful trials under laboratory and field conditions, these microbes are being used to degrade chemical pesticides in agriculture. As of now 2.56 billion kg of chemical pesticides is used every year to protect agricultural fields against pest attack. These technologies have been found to be highly effective, eco-friendly and cost-effective without disturbing the agro-ecosystems. As this book contains review articles contributed by various researchers from different countries whose work demonstrates recent advances in microbial degradation of pesticides, it will serve as a ready reckoner and also a valuable quick reference guide for scientists, academicians, cultivators and industrialists alike.

Download or read book Mandated Science Science and Scientists in the Making of Standards written by L. Salter and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: For a long time I would not eat strawberries. In 1977, a scandal broke about a testing laboratory having falsified the data that was used to register a large number of pesticides. The Canadian government, along with several others, began the process of re-evaluating both the procedures for testing and these specific chemicals. One chemical proved particularly controversial, the commonly-used pesticide named captan. In light of the controversy, which was manifest in a conflict between two government departments, in 1981, the Canadian government chose to appoint a special panel of experts to advise them. I was a member of this expert committee. The experience on the captan committee did little to reassure me, either about captan or about the way that decisions had been made about many pesticides in widespread use. Although it could not be demonstrated that captan was dangerous to people in the amounts to which they would likely be exposed, the animal studies provided the basis for concern. Prudence required at the very least that consumers take the precaution of washing their fruit, for captan is widely used on apples, cherries and berry fruits. Captan residues wash off apples relatively easily; they are less easily removed from berry fruits, such as straw berries.
