Tóm tắt

Thallium-related industrial materials (TIMs) from the mining and smelting of lead-zinc ores may lead to thallium (Tl) contamination in the soil. Building upon the soil column experiments, this study employed the diffusive gradients in thin-films (DGT) technique and the DGT-induced fluxes in soils (DIFS) model to understand the migration and distribution characteristics of Tl from lead-zinc industrial raw materials to soil, as well as its adsorption-desorption kinetics in soil. The results indicated that Tl concentrations in the leachate from fly ash (0.3 μg L
