Abstract:
Exposure scenario for risk assessment of pesticides is an integration of a region with all conditions closely related to agricultural production and pesticide utilization in the area and an indispensable means of using exposure assessment models in pesticide risk assessment. A lot of works on exposure scenario construction have been done in EU and US with a rich accumulation of experience. In recent years, China has also unfolded gradually its work on construction of exposure scenarios. A review is presented summarizing progresses EU and US have made in development of construction of upland-crop-surface-water pesticide exposure scenario systems, including the principles, methods and processes of scenario construction and scenario systems already set up. The progress on the development of exposure scenario in China has been analyzed, in an attempt to provide some scientific reference for the development of an upland crop-surface water pesticide exposure scenario system in China.
