Data collection initiatives of the crop protection industry – A mission to improve non-dietary risk assessment in Europe

Abstract

Plant protection products (PPPs) undergo rigorous safety assessments. In Europe, non-dietary risk assessments for operators, workers, bystanders and residents are highly conservative as this area of exposure science has historically been data poor. CropLife Europe (CLE) companies have collaborated to generate new data and pool existing data to refine the approaches prescribed by the European Food Safety Authority (EFSA) guidance on non-dietary exposure (2022).

This article summarises key activities, beginning with the development of the Agricultural Operator Exposure Model (AOEM) and covers projects which refine current approaches to bystander, resident and re-entry worker assessment, including the Bystander Resident Orchards Vineyards (BROV) project, improvements to the Bystander and Resident Exposure Assessment Model for spray drift (BREAM), proposals for refined vapour inhalation assessments, and a meta-analysis of Dislodgeable Foliar Residue (DFR) data. A study quantifying the benefits of using closed transfer systems, an appraisal of the inherent compounded conservatism in current risk assessment paradigms and the development of a new seed treatment model by the SeedTROPEX taskforce are also introduced.

These industry-led activities underscore the critical role of non-dietary exposure in the registration process for PPPs and reflect an ongoing commitment to provide farmers with effective crop protection solutions while ensuring safety.
