This book was released on 2012-12-06 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: International concern in scientific, industrial, and governmental communi ties over traces of xenobiotics in foods and in both abiotic and biotic envi ronments has justified the present triumvirate of specialized publications in this field: comprehensive reviews, rapidly published research papers and progress reports, and archival documentations. These three international publications are integrated and scheduled to provide the coherency essential for nonduplicative and current progress in a field as dynamic and complex as environmental contamination and toxicology. This series is reserved ex clusively for the diversified literature on "toxic" chemicals in our food, our feeds, our homes, recreational and working surroundings, our domestic animals, our wildlife and ourselves. Tremendous efforts worldwide have been mobilized to evaluate the nature, presence, magnitude, fate, and toxi cology of the chemicals loosed upon the earth. Among the sequelae of this broad new emphasis is an undeniable need for an articulated set of authoritative publications, where one can find the latest important world literature produced by these emerging areas of science together with docu mentation of pertinent ancillary legislation. Research directors and legislative or administrative advisers do not have the time to scan the escalating number of technical publications that may contain articles important to current responsibility. Rather, these individu als need the background provided by detailed reviews and the assurance that the latest information is made available to them, all with minimal literature searching.

This book was released on 2013-03-14 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years public awareness of the long term toxic affects heavy metal ions in waters and wastewaters has increased significantly. Environmental agencies have been imposing more and more stringent discharge limits on industries involved in processes using metal ions. Numerous industries produce aqueous effluents con taining metal ions and particularly copper and cadmium. Copper sulfate is used on a large scale in the electroplating industries. In addition, copper salts are used as fungicides, timber preservatives, insecticides, paint corrosion inhibitors and in dyestuffs. Cadmium is used in the manufacture of nickel-cadmium batteries, as a corrosion inhibitor and control rods in the nuclear industry. The European Com munity has listed cadmium as one of the most dangerous metal due to its toxicity, persistence and bioaccumulation in List 1 of its Directive 76/464/EEC. Therefore, it is important that methods for the removal of these metal ions are found and that the mechanism of removal is characterized and understood. A number of adsorb ents have been identified which are capable of removing copper (Panday et aI. , 1985; Ho et aI. , 1996; Low and Lee, 1987; Low et aI. , 1993; Quek et aI. , 1998) and cadmium (Battacharya and Venkobachar, 1984; Namasivayam and Ranganathan, 1995; Periasamy and Namasivayam, 1994) from aqueous solutions. Sorption kin etic models have been proposed for some systems.

Download or read book Nitrification and Denitrification written by Ivan Zhu and published by BoD – Books on Demand. This book was released on 2017-07-05 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrification and denitrification are essential processes for aquatic ecological system and vital for human health. While ammonia is applied for disinfection together with chlorine to produce chloramine, excessive ammonia may cause nitrification and bacteria growth in water transmission pipeline. Since excessive discharge may cause eutrophication and deterioration of aquatic system, nitrate is regulated for wastewater discharge in sensitive areas. Further, nitrate needs to be monitored and controlled in drinking water treatment to protect against methemoglobinemia in bottle-fed infants.

Download or read book Pentachlorophenol and some related compounds written by International Agency for Research on Cancer and published by International Agency for Research on Cancer. This book was released on 2019-10-24 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume of the IARC Monographs provides evaluations of the carcinogenicity of pentachlorophenol, 2,4,6-trichlorophenol, 3,3',4,4'-tetrachloroazobenzene, aldrin, and dieldrin. Pentachlorophenol, aldrin, and dieldrin are classified as persistent organic pollutants under the Stockholm Convention. Pentachlorophenol has been widely used as a wood preservative and insecticide, but its production and use are now restricted. 2,4,6-Trichlorophenol has also been used as a wood preservative and insecticide, and in the synthesis of some fungicides. Aldrin and dieldrin are synthetic organochlorine pesticides used as broad-spectrum soil insecticides for the protection of various food crops, as seed dressings, and to control infestations of pests such as ants and termites. In several countries their use has been banned or severely restricted since the early 1970s. 3,3',4,4'-Tetrachloroazobenzene is not manufactured commercially but is formed during the production and degradation of chloroanilide herbicides such as propanil, linuron, and diuron. Exposure to all five agents considered may occur in the general population as well as in various occupational settings. An IARC Monographs Working Group reviewed epidemiological evidence, animal bioassays, and mechanistic and other relevant data to reach conclusions as to the carcinogenic hazard to humans of environmental or occupational exposure of these agents.

Download or read book Food Taints and Off Flavours written by M.J. Saxby and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contamination of food with extremely low levels of certain compounds can cause an unpleasant taste. This can result in the destruction of vast stocks of product, and very substantial financial losses to food companies. The concentration of the alien compound in the food can be so low that very sophisticated equipment is needed to identify the components and to determine its source. It is vital that every company involved in the production, distribution and sale of foodstuffs are fully aware of the ways in which contamination can accrue, how it can be avoided, and what steps need to be taken in the event that a problem does arise. This book provides the background information needed to recognize how food can become tainted, to draw up guidelines to prevent this contamination, and to plan the steps that should be taken in the event of an outbreak. The new edition has been extensively revised and updated and includes substantial new material on the formation of off flavors due to microbiological and enzymic action, and on sensory evaluation of taints and off flavors A new chapter on off flavors in alcoholic beverages has been added. Written primarily for industrial food technologists, this volume is also an essential reference source for workers in research and government institutions.

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.
