Randomized trial assesses coal mining's impact on water quality in Mokolo River, suggesting need for monitoring.

This study assesses the impact of trace metals from coal mining on the Mokolo River's water quality.
Water samples were collected from the Mokolo River and analyzed for 17 elements using microwave digestion.
Toxic and macro elements were measured to evaluate water quality against permissible limits.
Essential trace elements exceeded permissible limits, with maximum concentrations of Fe, Mn, and Mo reaching 6.62 mg/L.
Toxic metals like As, Cd, Cr, and Pb exceeded guideline limits during the wet season with concentrations from 0.02 to 0.33 mg/L.
Children living near the river showed higher vulnerability to metal contamination, with Hazard Quotient values up to 34.9.

Mamaregane et al. (2026) studied this question.
