Abstract

An integrated model, the Pesticide Runoff Model (PeRM), has been developed to predict pesticide losses due to runoff by considering the emission, degradation, adsorption and desorption of pesticides, as well as their movement in dissolved and adsorbed phases. The developed modeling system has been used to calculate the losses of atrazine from agricultural lands in the Kintore Creek Watershed, Ontario, Canada between 1988 and 1992. The modeling outputs have been verified against actual monitoring data, which were obtained from a water quality monitoring project carried out in the same watershed over the same period of time.

摘要

已经开发了一种综合模型——农药径流模型（PeRM），通过考虑农药的排放、降解、吸附和解吸，以及它们在溶解相和吸附相中的移动，来预测径流造成的农药损失。已使用所开发的建模系统来计算1988年至1992年期间加拿大安大略省金托雷溪流域农田中莠去津的损失。已根据实际监测数据对建模输出进行了验证，这些数据是从同一时期在同一流域开展的水质监测项目中获得的。
