Abstract

The use of drones for plant protection product (PPP) applications is increasing; however, field data are lacking for drift exposure to bystanders and residents, allowing one to compare different exposure scenarios. We determined the dermal exposure of bystanders from spray drift after drone application to bare soil, soybean crops, and peach tree orchards. Dermal exposure was increased in orchard crops at higher wind speeds and lower when mannequins were placed further away from the application site. Approximately 90% of the total spray drift was deposited on mannequins within 5 m from the field edge. Drift exposure after drone spraying was lower than predicted values for ground boom applications compared to predictions using knapsacks. In conclusion, our study confirms the operator and bystander exposure-related benefits of the use of drones for applying PPPs to field and orchard crops.

测量三种作物处理方案下无人机施药后漂移导致的旁观者皮肤接触情况

无人机在植物保护产品（PPP）应用中的使用正在增加；然而，缺乏对旁观者和居民的漂移暴露的现场数据，允许比较不同的暴露情景。我们测定了无人机在裸露的土壤、大豆作物和桃树果园施用喷雾漂移后旁观者的皮肤暴露。果园作物的皮肤暴露在较高的风速下会增加，而当人体模型被放置在远离应用地点时，皮肤暴露会降低。大约90%的总喷雾漂移沉积在离现场边缘5米范围内的人体模型上。与使用背包的预测相比，无人机喷洒后的漂移暴露低于地面吊杆应用的预测值。总之，我们的研究证实了使用无人机将ppp应用于大田和果园作物的操作员和旁观者暴露相关的好处。
