Implication

Randomized trial investigates heavy metals in soils near Pb–Zn mines, highlighting ecological risks.

Key Points

  • This study aims to assess heavy metal contamination in soils from Pb–Zn mining sites and predict future environmental capacity declines.
  • Analyzed surface soil (0–20 cm) and subsoil (20–60 cm) samples around Pb–Zn mining areas.
  • Employed geo-accumulation index, pollution load index, potential ecological risk index, and Monte Carlo health-risk assessment.
  • Utilized network environ analysis and dynamic environmental-capacity forecasting.
  • Severe contamination by Pb, Cd, and Zn observed, with Pb having the highest intensity.
  • Most sites classified as moderate to high ecological risk according to PERI.
  • Health risk assessments indicated children faced significantly higher risks due to Pb and As exposure.
