| 520 | |a"Losses of atrazine and metolachlor were monitored in transient runoff events at the outlet of an agricultural watershed. The streamflow hydrographs were decomposed into surface runoff, interflow, and baseflow. The majority of losses of the applied herbicides occurred in surface runoff and interflow. The combined losses in surface runoff and interflow accounted for up to 75% of atrazine and 65% of metolachlor, of the total loss. Vast majority of the losses occurred within 70 days of the application and during a large storm event, shortly after herbicide application. Herbicide concentrations showed a steady disappearance with pseudo first-order half-lives 54 days for atrazine, and 50 days for metolachlor"--Abstract. |
