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 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.
