Article Synopsis
- Since 2009, Brazil has worked to determine natural concentrations of potentially toxic substances in soil, focusing on the state of Minas Gerais, which has a history of mining.
- The study involved sampling 697 georeferenced soil sites to evaluate the natural concentrations of metal(loid)s and understand spatial variability, using rigorous methodologies.
- Findings revealed that soil properties reflected deep acid weathering and that geological diversity was a key factor in metal(loid) concentration variability, leading to the conclusion that one Quality Reference Value is insufficient to represent the state's geochemical diversity.
