Mercury contamination in soil is managed through phytoremediation via Salvinia natans, indicating effective treatment methods.
Toxicity analysis showed that biomass with 1 mg Hg·kg−1 poses no significant environmental risk, enabling safe reuse in soil.
Physiological changes like chlorosis were noted at this concentration, emphasizing the need for monitoring during treatment.
Microbiological tests identified notable shifts in bacteria and fungi populations due to mercury levels in the substrate, demanding management strategies.
