Since the EU Directive (EC) No 128/2009 (SUD) was approved by the European Parliament, the establishment of a general framework aimed at securing the sustainable use of pesticides was laid down, and European Union (EU) Member States adopted National Action Plans in accordance with this Directive. Specifically, for EU Member States, pesticides, objectives and quantitative targets were created. Therefore, the EU Commission provided a methodology for risk assessment as the derivation of two harmonised risk indicators: HRI_1 and HRI_2. The present study focuses on HRI_1, as this can be implemented at the country level. Each EU Member State delivers annual harmonised risk indicators values to the Commission based on calculations using their own data and results. However, only the EU Commission can derive this HRI_1 (concatenated) indicator at the EU level. Therefore, the present study is an attempt to shed some light on the modus operandi used by the EU Commission to compile this HRI_1, and it also aims to clarify these calculations. Data originating from twenty-seven EU Member States were analysed. These data were compared to data published on the EU Commission website over time. Possible virtual developments including the modification and evolution of active substance statuses are envisaged.

自欧洲议会批准欧盟指令 (EC) No 128/2009 (SUD) 以来，制定了旨在确保农药可持续使用的总体框架，欧盟 (EU) 成员国采取了国家行动根据本指令制定计划。具体来说，为欧盟成员国制定了农药目标和定量指标。因此，欧盟委员会提供了一种风险评估方法，源自两个统一的风险指标：HRI_1 和 HRI_2。本研究重点关注 HRI_1，因为这可以在国家层面实施。每个欧盟成员国根据使用自己的数据和结果进行的计算，向委员会提交年度统一风险指标值。然而，只有欧盟委员会才能在欧盟层面得出此 HRI_1（级联）指标。因此，本研究试图阐明欧盟委员会编制此 HRI_1 的操作方式，并旨在澄清这些计算。对来自二十七个欧盟成员国的数据进行了分析。这些数据与欧盟委员会网站上随时间发布的数据进行了比较。设想了可能的虚拟开发，包括活性物质状态的修改和演变。
