Environmental Protection and Risk Assessment of Organic Contaminants

Contents

Environmental and human health risks: organic contaminants in soil environment - environmental fate, impacts, and remediation; PAHs in the soil environment and their bioavailability; risk assessment methods and their approaches with particular reference to organic compounds at gasworks sites; terrestrial ecotoxicity tests using soil fauna and flora; environmental concentration of pesticides in cotton production systems - risk assessment by fugacity modelling. Environmental fate and off-site migration: extrapolation of pesticide sorption data between agroclimatic regions; wetland rice ecosystem - a favourable environment for pesticide biodegradation; transport of sediments and pesticides in surface water; groundwater vulnerability assessment for pesticides at the plot, field, and regional scale. Management and remediation: problems and issues relating to pesticide residues in food and the enviroment - the Malaysian experience; minimising environmental contamination by selecting appropriate herbicide dose; bioremediation of PAH-contaminated soil - factors limiting and strategies for improving the degradation of benzo(a)pyrene.
