The spatial characteristics, pollution sources, and risks of soil heavy metals were analyzed on Hainan Island. results showed that the heavily polluted points accounted for 0.56%, number mildly above 15.27%, respectively, which mainly distributed in northern part study area. principal component analysis-absolute score-multiple linear regression (APCS-MLR) positive matrix factorization (PMF) revealed four sources metals: agricultural cadmium, (Cd), industrial mining arsenic, (As), transportation zinc lead (Zn Pb), natural chromium, nickel, copper (Cr, Ni, Cu). human health risk assessment indicated average non-carcinogenic (HI) both adults children was within safe threshold (<1), whereas Cr Ni posed a carcinogenic (CR) to health. In addition, total (THI) potential children, while (TCR) remained relatively high, Monte Carlo simulation all <1, but index >1, indicating threshold. Meanwhile, nearly 100% 99.94% TCR values exceeded 1 × 10

Soil contamination by heavy metals is a global agricultural problem, as these elements can be absorbed plants and transferred to humans through the food pathway. Current assessment methods rely on in situ sample collection, which restricts evaluation process due number of samples that analysed associated costs. This study addresses need for more efficient cost-effective approach identifying areas at risk metal without logistical constraints physical sampling. To meet this challenge, we developed new Probabilistic Pollution Index (PPI), calculated integrating GIS tools with an 8-parameter probability-risk matrix identify potentially contaminated metals. The factors considered included roads, industrial sites, pH levels, soil organic matter content, terrain slope, texture, mining areas, drainage. Each parameter was classified reclassified produce map, categorizing each pixel into five levels risk. test PPI, data analysis, classification, reclassification were applied district Guarda, Portugal. PPI map revealed central portion Guarda municipality, along specific zones Celorico da Beira, Sabugal, Mêda, Pinhel, exhibited high-probability contamination. Given expanse within enhanced monitoring recommended Vila Nova de Foz Côa. index provides scalable, cost-effective, easily replicable tool potential hotspots sources processes Designed first-line method large-scale assessments, it supports governmental decision-making facilitates targeted mitigation strategies low-cost approach.
