Patterns of accumulation and baseline values for metals in agricultural soils from a copper mining region in southern Peru

Spatio-temporal evaluation of metals and metalloids in the water of high Andean livestock micro-watersheds, Amazonas, Peru

“…Similar results were reported by Ezzati et al [ 48 ] in eight agriculturally dominated watersheds in Sweden, where the impacts of agriculture on water quality, together with factors such as precipitation and temperature, contributed to increased nitrogen and phosphorus loads, with this effect being accentuated during drought. Concentrations of certain metals in water may be due to soil movement, as reported by Bedoya-Perales et al [ 49 ], who found high concentrations of As (70.9 mg/kg), Cd (7.1 mg/kg) and Pb (89.7 mg/kg) in agricultural soils in the Peruvian Andes, posing a risk of removal and insertion into nearby water sources.…”

Concentrations of Potentially Toxic Elements in Topsoils of Urban Agricultural Areas of Rome

“…Taken together, these analyses indicate that anthropogenic factors are closely involved in the high concentrations of PTEs in this study. Several prior studies have also used these analyses to confirm the anthropogenic causes of high PTE concentrations in the soils [46,48,100]. A study from Rome by Calace et al [56] also found that an anthropogenic cause (vehicular traffic) was associated with high concentrations of Cu, Ni, Pb, and Zn in the soils of parks and gardens in Rome.…”
