Abstract Exposure to pesticide spray drift during the application of plant protection products (PPP) in orchards poses potential health risks bystanders and residents. To address this concern, study aimed gather novel field data on exposure orchards. The research was conducted by Julius Kuehn-Institute (JKI), Federal Office Consumer Protection Food Safety (BVL), German Institute for Risk Assessment (BfR). From 2018 2021, method conducting trials analysis implemented. from multiple series performed between 2021 2022 allowed collecting dermal (PDE), inhalation exposure, ground sediment. considered various distances treatment area drift-reducing techniques. Adult child mannequins were used simulate bystanders’ petri dishes measure results showed that reduction settings (75% reduction) considerably reduced levels mannequins. Furthermore, a strong correlation PDE values adults children located next each other at same distance observed. This finding suggests possibility convert adult produced realistic residents treated area. It contributes better understanding PPP includes different reducing technique. If taken into account further development current risk assessment models, new management options safe PPP, including buffer strips or systems, might be available near future.
