The environmental pesticide distribution on non-target systems (soil, drift and agricultural plastics) during the application step at small periurban production units, was studied in open field and greenhouses, for different crops (tomato, lettuce, broccoli, strawberry and flowers) using different pesticides (endosulfan, procymidone, chlorothalonil, chlorpyrifos and deltamethrin). In all cases, soil was the most exposed non-target system. For greenhouses, a general pesticide distribution was found of approximately 2/3 for crop, 1/4 for soil and 1/20 for plastic, of the total amount applied. In horticultural open fields, although the distribution was very dependent on the crop size and type, soil was also the most exposed non-target subsystem. Pesticide drift seems not to be significant in these production units, whilst pesticide accumulation on agricultural plastics reached up to 45% of the total applied, for polyethylene mulching in strawberry fields.
在小型城郊生产单位应用步骤中，环境农药在非靶标系统（土壤、漂移和农用塑料）中的分布情况在露天和温室中进行了研究，涉及不同作物（番茄、生菜、西兰花、草莓和花卉）和不同农药（硫丹、咯菌腈、百菌清、毒死蜱和溴氰菊酯）。在所有情况下，土壤都是最易受影响的非靶标系统。对于温室，发现一个普遍的农药分布情况，大约 2/3 分布在作物上，1/4 分布在土壤上，1/20 分布在塑料上，这是施用量的总和。在园艺露天场地，尽管分布情况非常依赖于作物的大小和类型，但土壤也是最易受影响的非靶标子系统。在这些生产单位中，农药漂移似乎并不重要，而农用塑料上的农药积累量高达 45%，这是在草莓地使用聚乙烯覆盖物的结果。
