In response to an application to renew the approval of the active substance diquat, EFSA completed an assessment in 2015 under the second group of the renewal programme (Regulation (EC) No 1141/2010). During the subsequent consultation on the EFSA conclusion between the applicants and the European Commission, the need to reassess non-dietary exposure was identified. EFSA was asked to provide a statement to include: detailed calculations for uses other than the critical good agricultural practice (GAP) for potatoes; calculations of the exposure of bystanders and residents using the EFSA calculator of the EFSA guidance (2014) adapted according to the saturated vapour concentration approach; the application of the German approach (as defined by Martin et al. 2008) without modification; and an evaluation of whether re-entry worker exposure is required for the critical GAP (potatoes). The assessment includes uses supported by both applicants as well as representative uses for different application rates. The concerns identified in EFSA's original assessment for bystanders and residents are confirmed for all representative uses.
针对百草枯活性物质再批准申请，欧洲食品安全局（EFSA）于2015年根据再批准计划的第二组（欧盟法规(EC) No 1141/2010）完成了一项评估。在申请人与欧盟委员会随后就EFSA结论进行的磋商中，确定有必要重新评估非膳食暴露情况。要求EFSA提供一份声明，内容包括：除马铃薯关键良好农业规范（GAP）之外其他用途的详细计算；使用根据饱和蒸汽浓度方法调整后的EFSA指南（2014年）中的EFSA计算器计算旁观者和居民的暴露量；直接应用德国方法（如Martin等人2008年所定义）不作修改；以及评估关键GAP（马铃薯）是否需要重新评估再进入农田作业工人的暴露情况。该评估包括申请人支持的用途以及不同施用量的代表性用途。EFSA最初评估中确定的关于旁观者和居民的问题在所有代表性用途中均得到证实。
