Description:
Multi-compartment monitoring of residue levels of OCPs in coastal marine environment of Mumbai has been studied. The concentration of total HCHs in seawater varied from 0.16 to 15.92 ng/L and concentrations of total DDT varied from 3.01 to 33.21 ng/L. The total HCH concentration in the sediment samples was in the range of 3.8 to 16.2 ng/g. @c-HCH contributed almost 55% to the total HCH. In sediment samples the DDT has higher mean concentration in comparison to its metabolite DDE and DDD. The concentration of total HCHs in different marine species varied from 0.87 to 33.73 ng/g and concentrations of total DDT varied from 0.38 to 34.1 ng/g. The variation in the @b-HCH in different compartments is not significant and this could be due to the high persistence and metabolically inactive nature of this isomer. The @a-HCH is found to be more dominant in fish samples whereas the @c-HCH is major contributor in the sediment samples. ... Read more

Product Description
Each Health Advisory gives the useful and relevant data on the health effects associated with each contaminant, and gives concentrations of the contaminant that would not cause adverse health effects during various periods of exposure. Complete sections also cover information on available analytical methods and treatment techniques for the contaminants. This essential technical guide is a must for water treatment plant supervisors, managers and operators. Federal, state, local and public officials who are responsible for drinking water quality and public health in the event of emergency spills or pesticide contamination will value this easy-to-use reference. ...

Product Description
This book is devoted to exploring the mechanism of pesticide movement into groundwater. It describes how pesticides enter ground water/drinking water systems and how regulatory decisions based on these mechanisms will affect the use of pesticides. Experimental results, models, and industry and regulatory perspectives are covered. ... Read more

Product Description
This much-needed collection of research by international and multidisciplinary experts explores the economic, environmental, and health benefits, as well as harmful consequences, of pesticide use in Thailand and elsewhere in Southeast Asia.

Population growth, the expansion of world trade, increased demands for quantity and quality of agricultural and other commodities, and the need to control vector-borne diseases over the past sixty years have given rise to a proliferation of synthetic chemical pesticides in both developed and developing nations. Since the publication of Rachel Carson's Silent Spring in 1962, the easily perceived immediate benefits of pesticides have been tempered by concerns about their more subtle long-term environmental and health consequences. The use of pesticides is often justified as beneficial in economic terms, but the amounts and allocations of the direct and indirect costs have come into question.

The book includes descriptions of pests and the pesticides used to control them. Authors give several perspectives on questions of safety, cost, and benefit for the environment, economy, and public health. Representatives of pesticide and commodity producers argue for the low-risk benefits of pesticides if they are properly used; research scientists present information on health and environmental consequences of the actual patterns of use by farmers; economists present data on costs and their allocation; and development agency representatives describe methods of reducing hazards through farmers' field schools and integrated pest management, and discuss the procedures and problems of international control of pesticides. ...

Product Description
Developing safety regulations for pesticides used around the world—in excess of 2.5 million tons annually—requires reliable analytical methods for assessing their impact in food and in the environment. Analysis of Pesticides in Food and Environmental Samples presents the most effective techniques for analyzing pesticide residues and other chemical contaminants in foods as well as in soil, water, and air.

Renowned Scientists Report New Data and Advances in the Field

The book introduces sample preparation, extraction, and analytical methods specific to each sample type, including foods from vegetal and animal origin. Other chapters discuss important aspects of quality assurance and the applicability of hyphenated analytical techniques. In addition to a practical chapter on the use of biosensors and immunoassays for monitoring and gathering exposure data, the book addresses regulatory aspects and presents current data on the levels of pesticides found in food and environmental matrices.

Latest Methods Help Scientists Develop Safer, More Effective Pesticides

Analysis of Pesticides in Food and Environmental Samples enables scientists to measure and predict the behavior and toxicity of pesticides with a higher degree of accuracy. The methodologies and insight in this timely work will contribute to the development of more effective, less toxic pesticides as well as better safety regulations. ... Read more

Product Description
The coastal tropics comprise some of the most sensitive and yet the most understudied ecosystems in the world. Coastal plains and river valleys are also home to agriculture on a vast scale and it is not surprising to find that streams and rivers receive the majority of agricultural runoff, carrying the residues of insecticides, fungicides and other pesticides into estuaries and coastal zone. Pesticide Residues in Tropical Coastal Ecosystems brings together toxicology experts from around the world to assess pesticide burdens in many of the major food-producing tropical countries. It provides a unique set of case studies, chronicling pesticide usage and its ecotoxicological impact in coastal regions.
A practical guide to recent research findings and applications, it is essential reading for environmental professionals, ecotoxicologists, marine chemists and agrochemists. ... Read more

Product Description
Research for this project started as the Granta Catchment Study in 1984 and it was designed to study and quantify the various aspects of pesticide occurrence and transport in the hydrological cycle. The National Rivers Authority recognizes the threat pesticides pose to aquifers across England and Wales and, as a result, has continued to investigate the problems in the Granta Catchment. The objectives of this work were: to determine the fate and transport of selected priority pesticides in surface and groundwater; to relate measured levels of pesticides to the patterns of use and physicochemical properties; and to develop predictive models of pesticide transport and fate. ...
