Implication

This review highlights contamination dynamics and remediation techniques for heavy metals in karst terrains, suggesting pathways for sustainable management.

Key Points

Abandoned smelting sites in karst areas pose significant environmental risks due to heavy metal contamination.
Contamination dynamics vary regionally, with high Cd levels like 23.36 mg/kg in surface soil in Guizhou, China.
Advanced molecular analysis methods, such as synchrotron-based XAS, enhance understanding of heavy metal speciation and toxicity.
Promising remediation methods include phytoremediation and bioremediation, but effectiveness relies on specific geochemical conditions.
