The study aims to assess the long-term effects of partial recultivation on metal(loid) contamination and environmental risks.
Analyzed metal(loid) concentrations in soil and pore water samples at a historical smelting site.
Conducted batch leaching tests and pH-static tests to evaluate metal mobilization and classification of slag waste.
High concentrations of Pb (111,000 mg·kg−1) and other metal(loid)s found in residual slag.
Slags classified as non-hazardous waste due to Pb release exceeding regulatory thresholds.
Peak mobilization of metals observed at acidic pH, indicating potential environmental risks.
