Abstract The southwestern region of Yunnan Province, China, is characterized by typical karst landforms, where the elevated concentration soil heavy metals has had significant impacts on local environment. objective this study was to investigate spatial distribution (Cu, Zn, Pb, Cd, and Cr) identify influencing factors in target area using geo-detector interpolation techniques. average chromium (Cr) exceeded background level elements being 1.35 times higher than value. concentrations other did not exceed levels, although individual sampling points showed values above standard. In terms distribution, high-concentration areas for all five were primarily located central part area. GeoDetector analysis revealed that pH, organic matter, GDP, evapotranspiration, rainfall, land-use type main metal. Interaction detector results factor interactions led either non-linear or two-factor enhancement. Among Cu, strongest interacting combination found between pH carbon (OC). This clarifies affecting metal regions provides a scientific evaluation method decision-making support similar with high values. findings hold value practical implications.

Abstract The availability of uncontaminated groundwater is pivotal significance for the sustainable sustenance human development. High concentrations heavy metals in can pose substantial risks to health. This study explores spatial distribution patterns, sources pollution, and health risk assessment (Mn, Ni, U, Zn, V, Cu, Cr, Cd Pb) shallow Huainan coal mining area China. Mn Ni were found be relatively high. characteristics analyzed using inverse distance weighting, revealing that Cd, Pb U was similar, suggesting typical point source pollution. PMF model indicated activities, industrial local geogenic processes main factors affecting quality, with contributions 42.76%, 440.78% 16.46%, respectively. results demonstrate non-carcinogenic each metal within safety threshold; however, carcinogenic posed by should not overlooked. It observed values children exceed those adults. Consequently, must undergo specific purification measures before utilization. findings this offer a scientific foundation ensuring quality drinking water plain areas affected mining.
