“…Glyphosate presence is widespread in the ecosystem ( ATSDR, 2020a ). Glyphosate is detected in particulate matter in the air emitted by rural roads, soils, including agricultural soils, sediments, water, and house dust ( Ramirez Haberkon et al, 2021 ; Battaglin et al, 2014 ; Van Bruggen et al, 2018 ; Rendón-von Osten and Dzul-Caamal, 2017 ; Curwin et al, 2005 ). Glyphosate is also detected in a variety of foods, including fruits, cereals, and pulses (i.e., dried seeds of legumes) ( USDA, 2011 ; Kolakowski et al, 2020 ; Zoller et al, 2018 ; EFSA, 2018 ; Rubio et al, 2014 ; Xu et al, 2019 ).…”

“…OC content in soils of rural roads was low (Figure 1), and most of the OC was associated to the PM10 (Figure 2). The low OC content in soils of rural roads can be attributed to the absence of a continuous supply of labile OC (due to lack of vegetation) and high rates of wind erosion (Ramirez Haberkon et al, 2021). In rural roads, OC tends to accumulate in PM10, which represents the stable fraction of OC that is protected chemically and physically (Hassink, 1997).…”

“…The OC contents in the PM10 emitted by rural roads is valuable information to quantify the OC losses from the soil and the OC discharges into the atmosphere by dust emission. In semiarid pampas, actual PM10 emission per unit of area of rural roads was 400 times higher than PM10 emission of agricultural soils (Ramirez Haberkon et al, 2021).…”

“…There are rural roads inside farm field (less traffic) and unpaved rural roads outside farm field (more traffic). Recent estimates suggest that the actual PM10 emission from rural roads is 409 times higher than that from agricultural soils (Ramirez Haberkon et al, 2021). Despite the significant contribution of rural roads to PM10 discharge into the atmosphere, the OC content in the PM10 specifically emitted by them remain unknown.…”

The aim of this study was to assess the organic carbon (OC) content in the PM10 emitted by agricultural soils and rural roads under controlled conditions. Samples were collected from agricultural soils and rural roads. The PM10 was generated and collected using an electrostatic precipitator coupled with the Easy Dust Generator (EDG). This procedure ensures that the PM10 collected come specifically from soil. OC contents were measured in both the soil and PM10. The enrichment ratio (ER) was calculated as the ratio between OC content in the PM10 and OC content in the soil. The results showed that OC content in the PM10 ranged from 2.7% to 3.5% in agricultural soils and from 1.4% to 2.9% in rural roads. These values were comparable with the OC contents observed in fine particles transported by the wind, but lower than OC contents observed in PM10 samples collected in rural areas using active samplers and filters. A quadratic function described the association between OC in PM10 and OC in the soil. A negative potential function described the association between ERs and OC in the soil. Both associations suggested a saturation of OC in PM10 when the OC content in the soil was high. This information is crucial for a better comprehending of the dust emission role in the redistribution of OC within terrestrial ecosystems and to the atmosphere and oceans.

“…Moreover, this is the first study that has been carried out in our region including a broawd range of pesticides. Even more, regional comparisons are limited, since there is scarce research in Argentina at multi-residue analysis levels comprising different pesticides in soils (except of glyphosate and AMPA) (Ramirez Haberkon et al, 2021). Fungicides inhibit the activity of β-glucosidase and dehydrogenase (Baćmaga et al, 2014;Monkiedje et al, 2002).…”

the crop cycle (27.5-53%, with respect to reference site values), whereas only acid phosphatase, β-glucosidase and carboxylesterase were lower at the end of the cycle (70.3%, 29.44%, and 45.79%; respectively). In the rice crop, dehydrogenase, acid phosphatase, and β-glucosidase activities were lower at the start of the cycle (27.88%, 50.32%, and 23.21%; respectively), with respect to reference site. However, the enzyme activity was lower at the end of the cycle compared to the reference site (dehydrogenase 20.47%, acid phosphatase 72.72%, β-glucosidase 57.77%, carboxylesterase 27.59%), except for urease activity. Current results suggested that the use of enzyme activities as indicators of soil quality is a viable approach to assess the pesticide impact in agricultural soils of Argentina.
