Stratigraphy-driven natural background for potentially toxic elements in a heavily mined Amazonian watershed

The Verde River watershed (VRW) in southeastern Amazonia is undergoing extensive channel modification and sediment disturbance from illegal alluvial gold mining, yet site-specific geochemical baselines capable of separating natural from mining-derived metal enrichment remain lacking. We integrated m...
