Trace elements in farmland soils and crops, and probabilistic health risk assessment in areas influenced by mining activity in Ecuador

“…For example, Hayford Svoboda et al, (2006), and Zhuang et al, (2009a, 2009b, reported elevated trace elements in agricultural soils and crops from mining areas in the Czech Republic and China, respectively. Similar findings were informed in areas influenced by mining activity in the central region of Peru, where the mean concentration of Cd (0.32 ± 0.23 mg kg −1 ) and Pb (0.20 ± 0.12 mg kg −1 ) in Lepidium meyenii Walpers (maca) samples exceeded the values established by the FAO/WHO guideline (Orellana Mendoza et al, 2021). In contrast, Marrugo-Madrid et al ( 2022) determined trace element contents below the threshold established in the regulations in fruits and tubers collected in the gold mining area of Colombia.…”

“…The concentrations of Cd and Zn from Ponce Enriquez were in the range reported by Orellana Mendoza et al (2021) in areas influenced by mining activity in the central region of Peru; yet, the content of Pb (72.11 ± 15.43 mg kg −1 ) was lower in our study. In contrast, the As concentration in the previously mentioned research (20.85 ± 5.79 mg kg -1 ) was several times lower than ours.…”

Effect of home processing methods on the levels of heavy metal contaminants in four food crops grown in and around two mining towns in Ghana

“…Food crops are able to absorb several heavy metals from the soils they are cultivated in depending on the physicochemical properties of the soils such as pH, organic matter content, clay fraction, mineral composition and the binding capacity of the soil [ [14] , [15] , [16] ]. Dheri et al [ 17 ] have explained that heavy metals dissolved in waste water and water bodies are easily transported to suspended solids.…”
