Quantitative source apportionment of soil heavy metals on a regional scale: Integrating input inventory, dual-isotope analysis and spatial decomposition modeling.
Quantifying the sources of soil heavy metal (HM) contaminants in mining-affected agricultural land is vital for effective pollution control and preventing food security issues. However, over large-scale agricultural regions, geogenic inputs, diffuse agricultural pollution (e.g., from fertilisation and irrigation), and...
