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.%农药风险评估暴露场景是某个区域与农业生产和农药使用密切相关的各种条件的综合,是风险评估中运用模型进行暴露评估时必不可少的.欧盟和美国在暴露场景构建方面开展了大量工作,积累了丰富经验,我国近年来也逐步开展了农药暴露场景构建工作.对欧盟和美国在农药旱地作物-地表水暴露场景体系构建方面的进展进行总结,包括场景构建的原则、方法、过程以及已形成的场景体系.同时,对我国农药暴露场景建立工作进展情况进行分析,旨在为我国农药旱地作物-地表水风险评估暴露场景的构建提供科学参考.
