Use of glyphosate

Schwientek et al. carried out a large meta-analysis of sites in Europe and the USA, and noticed differences in glyphosate and AMPA concentration patterns. They hypothesized that the presence of measured concentrations glyphosate and its transformation product AMPA in WWTP effluent cannot be attributed to the use of glyphosate as a herbicide. For this study they used data over the years 2014 until January 2023. The use of glyphosate as a herbicide in urban settings has been banned in some member

Formation of AMPA

AMPA can be formed by microbial degradation of glyphosate in soils and from photo-degradation of amino polyphosphonates in water (Grandcoin et al. 2017, Wang et al. 2020). These authors didn't indicate the formation of glyphosate from amino phosphonates. Biodegradation of phosphonates is not or only slightly possible (Horstmann and Grohmann 1988, Nowack and Baumann 1998, Drzyzga et al. 2017). In a recent paper Riedel et al. (2024) managed to identify a bacterial strain that can use phosphonates

Conclusions

Schwientek et al. argue that there should be another source of glyphosate, and that AMPA or other phosphonates may well be converted into glyphosate. However, they do not take into account physical/chemical proof on glyphosate and polyphosphonate degradation and the use of glyphosate as a herbicide in the urban environment during the period they investigated. No analytical or mechanistic data are presented, and their claims contradict scientific findings. They focused more on the number of

评论 “欧洲河流中的草甘膦污染不是由除草剂应用引起的？作者：M. Schwientek， H. Rügner， S.B. Haderlein， W. Schulz， B. Wimmer， L. Engelbart， S. Bieger， C. Huhn;水研究第 263 卷，2024 年 10 月 1 日，122140，第 1-10 页。

 部分片段

 草甘膦用途

Schwientek 等人对欧洲和美国的地点进行了一次大型荟萃分析，并注意到草甘膦和 AMPA 浓度模式的差异。他们假设 WWTP 废水中存在测量浓度的草甘膦及其转化产物 AMPA，这不能归因于使用草甘膦作为除草剂。在这项研究中，他们使用了 2014 年至 2023 年 1 月的数据。一些成员已禁止在城市环境中使用草甘膦作为除草剂

 AMPA 的形成

AMPA 可以通过土壤中草甘膦的微生物降解和水中的氨基多膦酸盐的光降解形成（Grandcoin 等人，2017 年，Wang 等人，2020 年）。这些作者没有说明氨基膦酸盐形成草甘膦。膦酸盐的生物降解不是或只有一点点可能（Horstmann 和 Grohmann 1988，Nowack 和 Baumann 1998，Drzyzga 等人，2017 年）。在最近的一篇论文中，Riedel 等人（2024 年）设法确定了一种可以使用膦酸盐的细菌菌株

 结论

Schwientek 等人认为，草甘膦应该有另一个来源，AMPA 或其他膦酸盐很可能转化为草甘膦。然而，他们没有考虑草甘膦和多膦酸盐降解的物理/化学证明，以及在他们调查期间在城市环境中使用草甘膦作为除草剂的情况。没有提供分析或机械数据，他们的说法与科学发现相矛盾。他们更关注
