Resumen:
Toxicity persistence in runoff water and soil was studied in experimental soybean plots in successive runoff events produced by an irrigation system. Three chlorpyrifos applications throughout the growing period were assayed. Runoff and soil toxicity to the amphipod Hyalella curvispina and the fish Cnesterodon decemmaculatus was assessed. Toxicity persistence to H. curvispina was shorter in the early and midseason applications (23?28 and 21?69 days in runoff and soil, respectively) and longer in the late application (more than 140 days). The same trend was observed for C. decemmaculatus: 13 days for early and 56 for the late application.
