This study investigates the spatiotemporal trends and health risks of nine atmospheric heavy metals (Pb, As, Mn, Ni, Cr, Cd, Zn, Cu, Fe) in PM2.5 across 50 Chinse cities, comparing resource-industrial cities (RICs) general (GCs) before (2014–2018) after (2019–2021) China’s 2018 Air Pollution Prevention Control Action Plan. Post-2018, concentrations all except Fe declined significantly (33–77%), surpassing reductions (25%). Geospatial analysis revealed elevated metal levels northern southern regions China, aligning with industrial mining hotspots. While RICs exhibited persistently higher than GCs, inter-city gap narrowed post-2018, achieving greater reduction. Pre-2018, combined non-carcinogenic hazard index (HI < 1) remained below safety thresholds, but carcinogenic risk total (CRT) for children exceeded 10−4, driven primarily by As Cr(VI). HIs were 1.5–2.0 times GCs. CRT 69.0–71.1%, reduced levels. Despite improvements, CRTs necessitate targeted mitigation (contributing 81.1–86.2% to CRT) Cr(VI) (11.7–14.0%). These findings validate policy’s effectiveness curbing vehicular emissions underscore need metal-specific controls resource-intensive safeguard child health.

Identifying the source and impact pathways of soil heavy-metal pollution is critical for its assessment remediation. Numerical simulation has been widely used to simulate processes predict risks. However, traditional numerical software requires a large number parameters, which are difficult obtain in site-scale studies. This study proposes rapid method identifying using TOUGH2/EOS7 software. It automatic calibration uncertainty analysis capabilities, can effectively reduce demand parameters. established method, including model selection, simulation, validation, error analysis, verify effectiveness proposed method. identified most realistic scenario chromium simulated release over 20 years, results met accuracy requirements with best-case fit 0.9998.
