Off-target deposition is one of the major routes of pesticide entry into the environment. Several studies have been carried out employing different tracers in an attempt to estimate pesticide deposition in the environment. This paper, in contrast, reviews different off-target sampling methods using the pesticide active ingredient. A critical analysis has been conducted on the sampling methods as applied to (a) pesticides of different volatilities, (b) samplers constructed using different materials, and (c) global distribution of the studies carried out on different pesticides using these samplers. In the last twenty years, pesticide deposition sampling has been carried out using various samplers such as chromatography paper, glass and plastic petri dishes, glass microscope slides, stainless steel rods and discs, amongst others. Of these, most studies have reported the use of chromatography paper because of the numerous advantages that it possesses, including protecting the pesticides from photodegradation and volatilisation. Air dispersion software models applied to pesticide deposition have tended to either over-predict or under-predict the amount of surface deposition resulting from pesticide spray drift. In conclusion, more work needs to be done to standardise pesticide deposition monitoring methods, including the choice of the most appropriate sampler for a particular situation, in order to obtain comparable and accurate data.

脱靶沉积是农药进入环境的主要途径之一。为了估计农药在环境中的沉积，已经进行了几项使用不同示踪剂的研究。相反，本文回顾了使用农药活性成分的脱靶采样方法。已对适用于（a）不同挥发性农药的采样方法，（b）使用不同材料构造的采样器以及（c）使用这些采样器对不同农药进行的研究的全球分布进行了严格的分析。在过去的二十年中，使用各种采样器进行了农药沉积采样，例如色谱纸，玻璃和塑料培养皿，玻璃显微镜载玻片，不锈钢棒和圆盘等。这些，大多数研究都报告了使用色谱纸的原因，因为它具有许多优点，包括保护农药免于光降解和挥发。应用于农药沉积的空气分散软件模型趋于过高或过低地预测了由农药喷雾漂移引起的表面沉积量。总之，需要做更多的工作来标准化农药沉积物监测方法，包括为特定情况选择最合适的采样器，以便获得可比较且准确的数据。应用于农药沉积的空气分散软件模型趋于过高或过低地预测了由农药喷雾漂移引起的表面沉积量。总之，需要做更多的工作来标准化农药沉积物监测方法，包括为特定情况选择最合适的采样器，以便获得可比较且准确的数据。应用于农药沉积的空气分散软件模型趋于过高或过低地预测了由农药喷雾漂移引起的表面沉积量。总之，需要做更多的工作来标准化农药沉积物监测方法，包括为特定情况选择最合适的采样器，以便获得可比较且准确的数据。
