Implication

Environmental monitoring study demonstrates distinct microbial degradation pathways across river basins, indicating severe anaerobic conditions driven by urban land use.

Key Points

To assess river water quality and identify critical pollution hotspots by linking water chemistry and microbial activity to regional land-use changes.
Monitored water chemistry and microbial activity across four major river basins (Pahang, Kuantan, Belat, and Galing).
Analyzed water samples using ion chromatography and portable water quality monitoring devices to evaluate metabolic responses to anthropogenic land use.
Significant differences in chemical oxygen demand (COD) across rivers established COD and related biological reactions as the primary indicators of anthropogenic degradation.
Pahang, Kuantan, and Belat rivers exhibited low wastewater inputs and maintained self-purification capacity through aerobic microbial oxidation and bacterial nitrification.
Galing River was dominated by anaerobic organic decomposition, specifically microbial denitrification and sulfate reduction, with maximum pollution concentrated in upstream industrial and commercial centers.
