Technical Abstract: In contrast to numerous reported studies on the environmental fate of pesticides at low concentrations, our knowledge of pesticide fate and behavior at elevated concentrations is far more limited. During the last two decades, few studies have been reported that have elevated concentrations as the objective of investigation. However, research on pesticide behavior at elevated concentrations has intensified recently due to the realization of the magnitude and significance of point-source contamination and that an array of potentially effective remediation tools need to be developed for these sites. The objectives of this chapter are: to review the observed differences in pesticide fate and behavior, more specifically degradation, sorption, transport, and persistence at elevated versus normal concentrations; to discuss the factors that may have contributed to these differences; and to present some ambiguous aspects that require further research.
