“…However, the transport of this herbicide to the atmosphere is also produced by vaporization of droplets during local or surrounding applications; for this reason, glyphosate may be present in stormwater runoff, with an average of 2.9 μg L −1 (Lamprea & Ruban, ). Due to their continuous introduction into the environment, glyphosate and AMPA can be considered as ‘pseudo‐persistent’ pollutants (Primost, Marino, Aparicio, Costa, & Carriquiriborde, ), which may be able to cause the same exposure potential as regulated persistent pollutants, as their high transformation and removal rates can be compensated by their continuous input into the environment.…”

“…In CH, the concentrations in the collected material will depend mainly on the predominant directions of the winds and the existence of input of material from other plots. In particles dissolved in water (material eroded by water from soils in crop production), the maximum glyphosate and AMPA concentrations were 562.8 and 210.4 μg kg −1 (Aparicio et al, ), and 548 and 475 μg kg −1 , respectively (Primost et al, ). In our study, the wind‐blown material or eroded material transported by the wind has average concentrations of 348 and 418 μg kg −1 for glyphosate and AMPA, respectively.…”

Agricultural intensification in fragile arid and semiarid environments has led to an increase in soil degradation, mainly through wind erosion. Argentina is an agricultural and cattle‐farming country, which has increased its productivity in the last few decades, widening the boundaries of farm land and the use of herbicides to control weeds. Glyphosate, which accounts for 65% of the Argentinian pesticides market, is strongly retained in soil. The World Health Organization concluded that there was evidence to classify glyphosate as ‘probably carcinogenic to humans.’ In this context, the objective of this study was to determine the presence and concentration of glyphosate and aminomethylphosphonic acid (AMPA) in wind‐blown material in 3 areas in Argentine semiarid regions (Chaco, La Pampa, and San Luis). In 1‐ha2 plots, left uncovered and levelled, the wind‐blown material was collected at heights of 13.5, 50, and 150 cm during 18 erosion events. The wind‐blown material carried by the wind at a height of 150 cm had concentrations of 247 and 218 μg kg−1 of glyphosate and AMPA, respectively. This material was enriched 60 times in glyphosate and 3 times in AMPA as compared with the original soil. This shows that the eroded material can, potentially, have a negative impact on the ecosystem and also on human health, depending on the proportion of this material released into the atmosphere in suspension as particulate matter. This study is, to our knowledge, the first to report concentrations of glyphosate and AMPA in wind‐blown material under field conditions.

“…It has been concluded that glyphosate and AMPA often occur as run-off from fields originating from glyphosate-based herbicide application. These residues not only became ubiquitous or "pseudo-persistent" contaminants in surface water, in periods with increasing concentrations over the years (McKnight et al, 2015;Carvalho, 2017;Primost et al, 2017), but through surface waters they were shown to be able to reach the seas as well, as documented in Germany in the estuaries of the Baltic Sea (Skeff et al, 2015). Glyphosate and AMPA were also found at up to 2.5 and 0.48 µg/l in rain and up to 9.1 and 0.97 ng/m 3 in air, respectively in the USA in Mississippi, Iowa and Indiana States in 2004(Chang et al, 2011, where both have been identified in the same period as common surface water contaminants near agricultural fields (Majewski et al, 2014).…”

“…Although GlyBH use is almost limited to terrestrial application, information regarding occurrence and cumulative and/or background levels of glyphosate residues in soils have received less attention, especially at the European scale. In fact, despite some recent studies on the distribution of glyphosate and AMPA in soils from Argentina (e.g., Aparicio et al, 2013;Lupi et al, 2015;Primost et al, 2017), U.S.A. (e.g., Battaglin et al, 2014;Scribner et al, 2007) or Australia (e.g., Todorovic et al, 2013), in Europe, where the approval for GlyBH use will be decided by the end of 2017, information on occurrence and levels of these substances in soil is still very limited and out of date (Grunewald et al, 2001;Laitinen et al, 2006Laitinen et al, , 2007Laitinen et al, , 2009.…”

• Data on occurrence and levels of glyphosate residues in EU soils is very limited.• Glyphosate and its metabolite AMPA were tested in 317 EU agricultural topsoils.• 21% of the tested EU topsoils contained glyphosate, and 42% contained AMPA.• Both glyphosate and AMPA had a maximum concentration in soil of 2 mg kg Approval for glyphosate-based herbicides in the European Union (EU) is under intense debate due to concern about their effects on the environment and human health. The occurrence of glyphosate residues in European water bodies is rather well documented whereas only few, fragmented and outdated information is available for European soils. We provide the first large-scale assessment of distribution (occurrence and concentrations) of glyphosate and its main metabolite aminomethylphosphonic acid (AMPA) in EU agricultural topsoils, and estimate their potential spreading by wind and water erosion. Glyphosate and/or AMPA were present in 45% of the topsoils collected, originating from eleven countries and six crop systems, with a maximum concentration of 2 mg kg −1. Several glyphosate and AMPA hotspots were identified across the EU. Soil loss rates (obtained from recently derived European maps) were used to estimate the potential export of glyphosate and AMPA by wind and water erosion. The estimated exports, result of a conceptually simple model, clearly indicate that particulate transport can contribute to human and environmental exposure to herbicide residues. Residue threshold values in soils are urgently needed to define potential risks for soil health and off site effects related to export by wind and water erosion.
