• • Pb, Ni, and Cd exceeded risk screening values at 4.26%, 6.38%, and 4.26% of sampling points, respectively, indicating localized contamination requiring targeted remediation.
• • Geo-accumulation indices for all eight metals were below 0 (mean < 0), confirming overall clean soil, but Pb, Zn, Ni, Hg, and Cd showed slight pollution at specific points, necessitating hotspot management.
• • Monte Carlo simulation quantified that children had a 0.2% probability of non-carcinogenic risk and a 3.21% probability of unacceptable carcinogenic risk, while adults had 0.64% probability of carcinogenic risk, with Ni as the main contributor, highlighting the need for child-specific protection measures.
• • Sensitivity analysis identified skin adherence factor as highly sensitive for both adults and children, and As, Pb, and Ni as major contributors, guiding priority monitoring and risk mitigation strategies.
