Identification of the pollution sources and hidden clustering patterns for potentially toxic elements in typical peri-urban agricultural soils in southern China

Urban Farm DB summary

This study in Gaoming county, China, integrated PMF and K-means clustering to identify sources and contamination patterns of 8 potentially toxic elements (PTEs) in peri-urban agricultural soils. Average concentrations of PTEs were reported, with PMF identifying geogenic, industrial/traffic-related, and agricultural sources. The highest PTE concentrations were found in urbanized zones, confirming significant human impact and underscoring the dual influences of agriculture and urbanization on PTE contamination.
