Download or read book Chemical and Photochemical Transformation of Selected Pesticides in Aquatic Systems written by N. Lee Wolfe and published by . This book was released on 1976 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This report presents the results of laboratory studies to quantitatively predict chemical and photochemical transformation rates and products of pesticides in water. It includes a general discussion of relevant transformation processes and associated kinetic expressions. The processes treated in most detail are hydrolysis, direct photolysis, and reaction with singlet oxygen. Implications of other processes such as oxidation and sensitized photolysis are also discussed. Results of detailed studies are included for the pesticides, malathion, carbaryl, methoxychlor, captan, and 2,4-D esters. The measured rate constants and half-lives indicate that chemical and/or photochemcial processes of these compounds are likely to be important in the aquatic environment. Less extensive data is presented for the pesticides, atrazine, diazinon, parathion, and toxaphene, along with a discussion of available literature data.
Download or read book Environmental Dynamics of Pesticides written by V. Freed and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pesticides have played a significant role in increasing food production, and in view of growing worldwide food demand we can expect the use of these chemicals to increase. However, some of them have found their way into the biosphere and have been classi fied as persistent toxic chemicals. This has resulted in serious concern about environmental contamination. Since we are going to continue using chemicals, we should learn more about such aspects as their transport in the environment, the relationship of their physical-chemical properties to transport, their persistence in the biosphere, their partitioning in the biota, and toxicological and epidemiological forecasting based on physical-chemical properties. Environmental chemodynamics is the name given to a subject which deals with some of the above topics, utilizing the principles of such disciplines as chemistry, physics, systems analysis, modelling, engineering, and medical and biological sciences. To ensure the safety of the environment, we must know more about the chemodynamical behavior of pesticides and related chemi cals. The purpose of the symposium "Environmental Dynamics of Pes ticides" was to explore the concept of chemodynamics as applied to pesticides and thus may help in developing the emerging field of environmental chemodynamics. The symposium was held during the l37th National American Chemical Society Meeting at Los Angeles, California, during April, 1974. The three sessions in the sym posium were chai'red by Drs. V.H. Freed, D.G. Crosby, and R. Haque.

The chapters cover fundamental topics, from photocatalyst materials, surface-modified materials, reaction kinetics and reactor modelling, to translational research activities on chemical synthesis, energy conversion and water treatment. The applications of the new generation of LED irradiation sources and spectroscopic methods for elucidating reaction pathways are also covered in detail. This new volume maintains the ethos of the previous editions by further contributing to readers' understanding of photochemical and photocatalytic processes for environmental applications. .

Download or read book Pesticides written by R.P. Soundararajan and published by BoD – Books on Demand. This book was released on 2012-07-25 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pesticides are considered as potential molecules to combat insects, pests, diseases and weeds in agricultural, horticultural cropping system as well as health management systems. Pesticides of chemical origin are highly effective against the target organism. However, the chemical pesticides have toxic effects on several non-target species and the growing environmental concerns raises the issues of safety and evaluation of toxicity. In this book the effects of chemical pesticides on fishes, earthworms, beneficial microbes and natural enemies in agricultural ecosystems are discussed. Furthermore, pesticides have the properties to disrupt endocrine and non-traditional pesticide compounds have been elaborately narrated. The recent technology on use of biomarkers in pesticide assay is described in two chapters. Some of plants having pesticidally active compounds are described. Use of biotechnological approaches for insect pest management and a new approach to recognize larva in the field by LIRA classifier system are two more interesting chapters of the book.
Download or read book Residue Reviews R ckstandsberichte written by Francis A. Gunther and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: That residues of pesticide and other "foreign" chemicals in food stuffs are of concern to everyone everywhere is amply attested by the reception accorded previous volumes of "Residue Reviews" and by the gratifying enthusiasm, sincerity, and efforts shown by all the in dividuals from whom manuscripts have been solicited. Despite much propaganda to the contrary, there can never be any serious question that pest-control chemicals and food-additive chemicals are essential to adequate food production, manufacture, marketing, and storage, yet without continuing surveillance and intelligent control some of those that persist in our foodstuffs could at times conceivably endanger the public health. Ensuring safety-in-use of these many chemicals is a dynamic challenge, for established ones are continually being dis placed by newly developed ones more acceptable to food technologists, pharmacologists, taxicologists, and changing pest-control requirements in progressive food-producing economies. These matters are of genuine concern to increasing numbers of governmental agencies and legislative bodies around the world, for some of these chemicals have resulted in a few mishaps from improper use. Adequate safety-in-use evaluations of any of these chemicals per sisting into our foodstuffs are not simple matters, and they incorporate the considered judgments of many individuals highly trained in a variety of complex biological, chemical, food technological, medical, pharmacological, and toxicological disciplines.
