“…Despite the reduced mobility of glyphosate and AMPA in the tested soils, the weather conditions, dry in July but with intense D r a f t precipitation in August, would probably have washed away these molecules from the soil, transporting them to surface water and groundwater via either runoff or leaching. The relationship between rainfall and detection/concentration of glyphosate and AMPA in groundwater was also observed by Geng et al (2021), Mas et al (2020), and Rendón-Von Osten and Dzul-Caamal (2017). In particular, the latter observed that heavy rainfall shortly after glyphosate application poses a higher risk for glyphosate to move to the groundwater.…”

“…Moreover, the results of the National Water-Quality Assessment Program in the United States (Scribner et al, 2007), the data from the Dutch Groundwater Monitoring Network (Schipper et al 2008), and the National Report on pesticides in water in Italy (ISPRA, 2018) concur with results from previous studies that found that AMPA occurs more frequently and at similar or higher concentrations than glyphosate. Conversely, Geng et al (2021) observed a median AMPA ratio in groundwater of 36% with an interquartile range of 12-65% and a strong correlation between AMPA and glyphosate concentration (Pearson correlation r=0.887, p=0.008<0.01). Of the 649 samples analysed, glyphosate and AMPA were detected in six samples, but glyphosate was detected without AMPA in only one sample.…”

“…Spatial differences in glyphosate and AMPA occurrence in groundwater could also be related to the crop. Analysing glyphosate and AMPA in groundwater and surface water in agricultural areas in 10 Chinese provinces, Geng et al (2021) observed different detection frequencies in relation to the proximity to different crops. They found the highest detection frequency in the groundwater samples close to soybean (5.3% for both glyphosate and AMPA), followed by rice (3.2% for both glyphosate and AMPA), maize (0.3% for both glyphosate and AMPA), and vegetables (0.7% for glyphosate and 0% for AMPA), whereas no detection was observed in the samples close to wheat, apple, pear, sunflower, and sugarcane.…”

“…It is essential to note that the European drinking water standard is much more conservative than the guidelines established by Mexico, Canada, Argentina, Brazil, the United States, and China.

Review of studies analysing glyphosate and aminomethylphosphonic acid (AMPA) occurrence in groundwater

2022

The herbicide glyphosate (N-phosphonomethylglycine) has been the most commonly applied herbicide worldwide for the past 40 years. This review aims to present and discuss the state of knowledge concerning groundwater contamination by glyphosate and its metabolite, aminomethylphosphonic acid (AMPA). A dataset of 48 reports and articles reporting glyphosate and AMPA detection in groundwater worldwide was constructed from published literature. Specific attention was given to the analysis of available studies on glyphosate and AMPA transport in groundwater to investigate groundwater contamination factors. The information presented in this review highlights detectable groundwater contamination in several countries globally, with many cases exceeding European groundwater quality standards. Both agricultural and non-agricultural applications of glyphosate can be significant sources of pollution, and proximity to agricultural fields is a significant risk factor. AMPA has two primary sources, glyphosate and amino polyphosphates, but very little information is available about the origin of AMPA detected in groundwater. Glyphosate and AMPA transport to groundwater can be significant in well-structured soils rich in macropores, where it generally occurs via preferential flow. An inverse relationship was highlighted between the groundwater depth and glyphosate and AMPA occurrence and concentration in groundwater; however, some discrepancies among the studies were identified. Heavy rainfall shortly after glyphosate application poses a high risk of its transport to groundwater. Seasonal trends in glyphosate and AMPA in groundwater, related to application timing, agronomic practices, and weather conditions, were also observed. Finally, risk-management measures are proposed.

“…Of the active substances tested, glyphosate was evaluated as the most toxic to A. salina, which corresponds to the conclusions obtained from the toxicity evaluation of the herbicides containing it. Glyphosate and AMPA were found in different concentrations ranging between 0.04 to 700 µg•L −1 in a surface water [105][106][107][108][109][110] and between 52 to 3294 µg•kg −1 in soil [105,107,108]. Toxicity of glyphosate and its formulations have impact even at environmentally relevant concentrations.…”

The aim of this work was to determine the toxic effect of the most used herbicides on marine organisms, the bacterium Aliivibrio fischeri, and the crustacean Artemia salina. The effect of these substances was evaluated using a luminescent bacterial test and an ecotoxicity test. The results showed that half maximal inhibitory concentration for A. fischeri is as follows: 15minIC50 (Roundup® Classic Pro) = 236 µg.l−1, 15minIC50 (Kaput® Premium) = 2475 µg.l−1, 15minIC50 (Banvel® 480 S) = 2637 µg.l−1, 15minIC50 (Lontrel 300) = 7596 µg.l−1, 15minIC50 (Finalsan®) = 64 µg.l−1, 15minIC50 (glyphosate) = 7934 µg.l−1, 15minIC50 (dicamba) = 15,937 µg.l−1, 15minIC50 (clopyralid) = 10,417 µg.l−1, 15minIC50 (nonanoic acid) = 16,040 µg.l−1. Median lethal concentrations for A. salina were determined as follows: LC50 (Roundup® Classic Pro) = 18 µg.l−1, LC50 (Kaput® Premium) = 19 µg.l−1, LC50 (Banvel® 480 S) = 2519 µg.l−1, LC50 (Lontrel 300) = 1796 µg.l−1, LC50 (Finalsan®) = 100 µg.l−1, LC50 (glyphosate) = 811 µg.l−1, LC50 (dicamba) = 3705 µg.l−1, LC50 (clopyralid) = 2800 µg.l−1, LC50 (nonanoic acid) = 7493 µg.l−1. These findings indicate the need to monitor the herbicides used for all environmental compartments.

Estimating exposure is one of the most important steps in an environmental risk analysis of crop‐protection products to nontarget organisms. Regulatory agencies such as the US Environmental Protection Agency (USEPA), Pest Management Regulatory Agency (PMRA), and European Food Safety Authority (EFSA) all use mathematical exposure models in their regulatory assessment process. Brazil has been discussing the adoption of the Pesticide in Water Calculator (PWC) to be applied in aquatic pesticide risk assessment. Therefore, a qualitative sensitivity analysis (Morris OAT method) was performed to understand which are the most important local parameters in the PWC to estimate environmental concentrations in surface water (EECSW). In addition, an exercise made up of two corn scenarios in two Brazilian regions was developed (Uberlândia [UDI] and Arapoti [ARA]). Two herbicides with different soil‐binding properties and modes of action were selected to estimate the EECSW. The results demonstrated that the parameters of importance were different for each site, probably the result of different soil characteristics and meteorological patterns. This outcome suggests that regulatory agencies should consider developing more than one scenario to account for different agricultural regions. For Herbicide 1, the EECSW for UDI were similar to US scenarios, whereas for ARA they were lower. For Herbicide 2, the EECSW for the UDI site was higher than most of the US scenarios, whereas at the ARA site, EECs were similar to four US scenarios and lower than the other six. Local data were used as a refinement, resulting in the decrease in the EECSW for both herbicides in the UDI site. For the ARA site, Herbicide 1 displayed a similar EECSW value, whereas for Herbicide 2, it was lower after the refinement. Overall, these results demonstrated the importance of developing local scenarios to provide more realism to estimate pesticide exposure from its agricultural use and may help regulators to determine and recommend mitigations regarding the use of crop‐protection products.
