Abstract

A laboratory-scale experiment was conducted to evaluate the bioremediation of trace element–contaminated mining industrial soil using 5 L glass pot bioreactors. Mixed organic amendments including sheep manure, pig manure, vegetable waste, dry leaves waste, and stone slurry were applied. After treatment, soil pH increased from 5.30 to 7.54 and electrical conductivity decreased from 4510 to 3220 µS/cm. Significant removal efficiencies were observed for copper (85–88%), manganese (91–93%), lead (75–80%), zinc (55–62%), and iron (89–92%). The results demonstrate that microorganisms combined with organic amendments effectively improve soil properties and reduce toxic trace metals, indicating that this method is a feasible and sustainable approach for the treatment of contaminated mining soil.
