Spatial Differentiation and Integrated Risk Assessment of Heavy Metals in Paddy Soils Affected by Lead–Zinc Mining and Smelting

Subsurface contamination in mining-affected paddy soils raises questions about how concentration changes with depth relate to contamination persistence and metal partitioning. We sampled 46 paddy field sites in Guangdong, China, at 0–20, 20–40 and 40–60 cm. Total concentrations of eight elements were measured by induct...
