“…Glyphosate is thought to be immobile or slightly mobile in soil as it ionizes easily and, as anions, is adsorbed to the OM in soil or can compete with phosphorus (P) in adsorption areas (Prata, Camponez, Lvorenti, Tornisielo, & Borges, ) and correlates with soil pH (Lupi et al, ). It has been shown that the aggregates and/or particulates that are transported at a greater height are of a finer granulometry, have more capacity for adsorption, and are generally found to be enriched with elements such as organic carbon (C) and essential nutrients (Aimar, Méndez, & Buschiazzo, ; Zobeck & Fryrear, ).…”

“…During this period, successive applications of glyphosate are made, maintaining the possibility that more AMPA is generated by degradation and that it increases its proportion in the soil with respect to the glyphosate. Another study has also shown that the glyphosate and AMPA contents decreased from the surface up to 25 cm deep (Lupi et al, 2015), indicating that the highest concentration is found in the surface layer susceptible to be transported by the wind. However, the transport of this herbicide to the atmosphere is also produced by vaporization of droplets during local or surrounding applications;…”

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.

“…Glyphosate residue contamination has been demonstrated to correlate with sources of agricultural applications (Payne, 1992;Coupe et al, 2012) corresponding to GM crop cultivation (Barceló and Hennion, 1997;Skark et al, 1998;Australian Academy of Technological Sciences, and Engineering, 2002;Ramwell et al, 2002;Peruzzo et al, 2008;Aparicio et al, 2013;Davis et al, 2013;Mardiana-Jansar and Ismail, 2014;Lupi et al, 2015;Ronco et al, 2016;Caprile et al, 2017;, post-harvest chemical desiccation (Shipitalo and Owens, 2011;Soracco et al, 2018) or other technologies in intensive agriculture e.g., biomass production of industrial crops (Mardiana-Jansar and Ismail, 2014). Moreover, non-agricultural or urban uses of FIGURE 4 | Maximal residue levels (µg/l) of glyphosate (black) and AMPA (gray in parentheses) in surface and ground water reported worldwide.…”

“…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.
