Environmental impacts of toxic elements on crop-grazing soils in areas surrounding artisanal mining in the Brazilian Amazon

Key Points

• Contamination of crop-grazing soils was significantly detected with heavy metals.
• Lead and arsenic levels were notably higher in mining-affected areas than in non-mining regions.
• This observational analysis assesses soil quality based on soil samples collected from various sites.
• These findings may enable targeted interventions to mitigate environmental risks in agricultural practices.
