Provides an overview of analytical and environmental chemistry of herbicide metabolites. Covers methods and development strategies for the analysis of herbicides and their metabolites. Discusses advances in analytical methods, including applications for the analysis of herbicide metabolites in
water and soil. Addresses fate and transport of herbicides, including molecular interactions with soil, field-scale transport studies, and a larger scale study of the effects of topography and irrigation on the occurrence of herbicides and their metabolites in soil. Examines basin and regional scale
occurrence of herbicides and their metabolites in surface water and groundwater. Includes a EPA perspective on herbicide metabolites in groundwater.
