Glyphosate: ECHA and EFSA launch consultations
ECHA/NR/21/24
ECHA and the European Food Safety Authority (EFSA) have started parallel consultations on the initial scientific evaluations of glyphosate. The consultations will run for 60 days and all interested parties are encouraged to contribute.
Helsinki, 23 September 2021 – In the parallel consultations, ECHA will gather feedback to the Harmonised Classification and Labelling report on glyphosate. EFSA’s consultation is on the Renewal Assessment Report.
The initial scientific evaluations put out for consultation today were both prepared by the Assessment Group on Glyphosate (AGG), which comprises national competent authorities in France, Hungary, the Netherlands and Sweden.
ECHA and EFSA strive for transparency and to bring citizens and stakeholders as close to the Agencies’ work as possible. All interested parties are encouraged to contribute to the consultations by submitting relevant comments or scientific information and data. The consultations will remain open for 60 days and all comments will be published after their closure on the two Agencies’ websites.
After the consultations, each Agency will consider the comments relevant for their respective process.  For the harmonised classification process, the Assessment Group on Glyphosate and ECHA’s Committee for Risk Assessment (RAC) will consider the comments and data submitted.  These considerations will be taken forward when RAC develops its opinion on the classification of glyphosate under the Classification, Labelling and Packaging (CLP) Regulation.
The classification of chemicals is based solely on the hazardous properties of a substance and does not take into account the use or likelihood of exposure to the substance. Exposure is considered as part of the risk assessment of pesticide active substances, a process led by EFSA.
Glyphosate currently has a harmonised classification as causing serious eye damage and as toxic to aquatic life with long-lasting effects, prior to and following the assessment by ECHA in 2017. Classification for germ cell mutagenicity, carcinogenicity or reproductive toxicity was not considered to be warranted. The initial scientific evaluation from the AGG does not recommend a change to the existing classification.
EFSA will take the outcome of the ECHA’s RAC opinion on the classification of glyphosate into account in its peer review and is expected to finalise its work in the second half of 2022. The European Commission, together with risk managers from the 27 EU Member States, will then decide whether to renew the approval of glyphosate for use in the EU.
Background
Glyphosate is a chemical that is widely used in plant protection products (PPPs). Glyphosate-based PPPs – i.e. formulations containing glyphosate, co-formulants and other chemicals – are mainly used in agriculture and horticulture to control weeds that compete with cultivated crops.
The European Commission granted a five-year approval for glyphosate in 2017. It is currently approved for use in the EU until 15 December 2022. This means it can be used as an active substance in PPPs until that date, subject to each product being authorised by national competent authorities in the individual EU Member States following a safety evaluation.


草甘膦:ECHA和EFSA启动磋商
ECHA / NR / 21/24
欧洲经委会和欧洲食品安全局(欧洲食品安全局)已开始就草甘膦的初步科学评估进行平行磋商。协商将持续60天,并鼓励所有有关各方作出贡献。
赫尔辛基,2021年9月23日—在平行磋商中,欧洲经委会将收集对草甘膦统一分类和标签报告的反馈。欧洲食品安全局的咨询是关于更新评估报告。
今天公开征求意见的初步科学评估都是由草甘膦评估小组(AGG)准备的,该小组由法国、匈牙利、荷兰和瑞典的国家主管当局组成。
ECHA和EFSA努力提高透明度,使公民和利益相关者尽可能接近机构的工作。鼓励所有感兴趣的各方通过提交相关评论或科学信息和数据为协商作出贡献。磋商将持续60天,所有意见将在磋商结束后公布在两机构的网站上。
协商后,各机构将审议与各自进程有关的意见。在统一分类过程中,草甘膦评估小组和欧洲化学品管理局风险评估委员会(RAC)将考虑提交的意见和数据。当RAC根据《分类、标签及包装(CLP)规例》就草甘膦的分类提出意见时,我们会进一步考虑这些考虑。
化学品的分类仅仅基于一种物质的危险特性,而不考虑使用或接触该物质的可能性。暴露被认为是农药活性物质风险评估的一部分,这一过程由欧洲食品安全局牵头。
在2017年ECHA评估之前和之后,草甘膦目前有一个统一的分类,即造成严重眼睛损害和对水生生物具有长期影响的有毒物质。生殖细胞致突变性、致癌性或生殖毒性的分类不被认为是有保证的。AGG的初步科学评估并不建议对现有的分类进行更改。
欧洲食品安全局将在同行评审中考虑ECHA关于草甘膦分类的RAC意见的结果,预计将在2022年下半年完成这项工作。欧盟委员会将与来自27个欧盟成员国的风险管理人员一起决定是否延长草甘膦在欧盟的使用批准。
背景
草甘膦是一种广泛用于植物保护产品(PPPs)的化学物质。基于草甘膦的ppp——即含有草甘膦、联合配方和其他化学品的配方——主要用于农业和园艺,以控制与栽培作物竞争的杂草。
2017年,欧盟委员会批准了草甘膦的五年许可。目前,该产品已被批准在欧盟使用,有效期为2022年12月15日。这意味着在此日期之前,它可以作为PPPs中的活性物质使用,前提是每个产品都要经过欧盟成员国国家主管部门的安全评估后获得批准。


草甘膦是一种非选择性、无残留灭生性除草剂,对多年生根杂草非常有效,广泛用于橡胶、桑、茶、果园及甘蔗地。主要抑制植物体内的烯醇丙酮基莽草素磷酸合成酶,从而抑制莽草素向苯丙氨酸、酪氨酸及色氨酸的转化,使蛋白质合成受到干扰,导致植物死亡。草甘膦是通过茎叶吸收后传导到植物各部位的,可防除单子叶和双子叶、一年生和多年生、草本和灌木等40多科的植物。草甘膦入土后很快与铁、铝等金属离子结合而失去活性。
