The quality of farmland soil is crucial for human health and agriculture, necessitating an assessment of heavy metal pollution sources to mitigate risks.
This study used geostatistical analysis and an APCS-MLR model to identify and quantify pollution sources, revealing that metals like As, Cr, Cd, Pb, Zn, and Cu are enriched in the soil.
Major pollution sources include atmospheric deposition and agricultural activities, contributing significantly to ecological risks, accounting for 56.21% and 36.01%, respectively, thus highlighting the need for targeted pollution management strategies.
