Abstract :
Glyphosate has been banned in some herbicidal formulations. We analyse for the first time 14 marketed products where glyphosate was replaced by acetic, pelargonic, caprylic or capric acids, or even benzalkonium chloride, to be supposedly less toxic. 35 heavy metals, 16 polycyclic aromatic hydrocarbons (PAHs), and essential minerals were tested by specific mass spectrometry associated with gas chromatography or inductively coupled plasma methods in the formulations. Essential minerals do not reach toxic levels, but heavy metals are found at levels up to 39 mg/L, depending on the product, and include silicon, arsenic, lead, iron, nickel, and titanium. Their presence at up to several hundred times the admissible levels in water may be due to nanoparticles embedding pesticides. PAHs reach levels of 32–2430 μg/L in 12 of the 14 samples; for instance, the carcinogen benzo(A)pyrene was detected. It was found to be present at up to several thousand times above the norm in water, as was benzo(A)anthracene. These compounds did not add significant herbicidal effects. Low levels of glyphosate were detected in 2 samples. These variable levels of undeclared toxic chemicals violate European Union rules on pesticides and may have health and environmental consequences, especially when exposure is long-term.

与《Data in Brief》及《Food and Chemical Toxicology》杂志最新接受的论文《不含草甘膦的除草剂中的有毒化合物》相联系，该论文DOI：https://doi.org/10.1016/j.fct.2020.111770。摘要如下：草甘膦在某些除草剂配方中已被禁用。本研究首次分析了14种市售产品，其中草甘膦被乙酸、月桂酸、辛酸或癸酸，甚至苯扎氯铵所替代，以期降低其毒性。通过与气相色谱或电感耦合等离子体质谱方法相结合的特定质谱法，对这些配方的35种重金属、16种多环芳烃（PAHs）及必需矿物质进行了检测。必需矿物质未达到毒性水平，但重金属含量高达每升39毫克，包括硅、砷、铅、铁、镍和钛等，其含量可能因产品而异。这些重金属在水中的含量可能高达允许标准的数百倍，其存在可能与纳米颗粒中嵌入的农药有关。在14个样本中的12个样本中检测到多环芳烃，含量为32至2430微克/升；例如，致癌物苯并（a）芘被检测到，其在水中的含量可能高达标准值的数千倍，苯并（a）蒽的情况亦然。这些化合物并未显著增加除草效果。在2个样本中检测到低水平的草甘膦。这些未申报的有毒化学物质的含量变化违反了欧盟关于农药的规定，并可能对健康和环境产生长期影响。
