摘要

Several factors affect the occurrence and transport of pesticides in surface waters of the 29, 400 km~2 White River Basin in Indiana. A relationship was found between pesticide use and the Average annual concentration of that pesticide in the White River Although this relationship varies for different classes of pesticides. About one percent of the mass applied of each of the commonly Used agricultural herbicides was transported from the basin via the White River. Peak pesticide concentrations were typically highest In late spring or early summer and were associated with periods of Runoff following application.
