Risk Assessment of Pesticide Contamination of Surface Water and Groundwater - Trigger Mechanisms for Fast Transport

地表水和地下水农药污染的风险评估--快速运输的触发机制。农药和除草剂向地下水和地表水的运输对环境和人类都构成了风险。将开发一种新的基于事件的农药对地表水和地下水移动的风险评估方法。利用降雨模拟，农业集水区的地表径流和入渗之间的分配将被量化。农药污染事件将从气候数据中确定，如高强度降雨和控制径流和优先流的土壤特性。结果将用于制定管理战略，以减少杀虫剂的异地转移。

Risk Assessment of Pesticide Contamination of Surface Water and Groundwater - Trigger Mechanisms for Fast Transport. Pesticide and herbicide transport to groundwater and surface water poses a risk to the environment and humans alike. A new event-based risk assessment approach of pesticide movement to surface water and groundwater will be developed. With the use of rainfall simulation partitioning between surface runoff and infiltration will be quantified in an agricultural catchment. Pesticide contamination events will be identified from climatic data such high intensity rainfalls and soil properties controlling runoff and preferential flow. Results will be used to develop management strategies to reduce offsite movement of pesticides.
