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.
植保产品(PPPs)要经过严格的安全评估。在欧洲,对操作人员、工人、旁观者和居民的非饮食风险评估非常保守,因为这一暴露科学领域历史上数据匮乏。欧洲作物保护协会(CLE)的公司合作生成新数据并汇集现有数据,以完善欧洲食品安全局(EFSA)关于非饮食暴露的指南(2022 年)规定的方法。本文总结了关键活动,首先是开发农业操作人员暴露模型(AOEM),并涵盖了当前对旁观者、居民和重返工人评估方法进行改进的项目,包括旁观者居民果园葡萄园(BROV)项目、改进的喷雾漂移旁观者和居民暴露评估模型(BREAM)、对精细蒸气吸入评估的建议,以及可洗脱叶面残留(DFR)数据的荟萃分析。还介绍了一项量化使用封闭转移系统的好处的研究、对当前风险评估范式中内在复合保守性的评估,以及由 SeedTROPEX 工作组开发的新种子处理模型。这些由行业主导的活动强调了非饮食暴露在 PPP 注册过程中的关键作用,并反映了持续致力于为农民提供有效的作物保护解决方案,同时确保安全。
