ClearAssessment of Microplastic Pollution in Sediments and Water of River Soan, Punjab, Pakistan
Sampling at seven sites along Pakistan's River Soan found hundreds of microplastic particles per quarter-square-meter of water surface, with even higher concentrations in river sediments, and seasonal variation showing more particles in summer than winter. FTIR analysis identified a range of polymer types, pointing to diverse pollution sources in this South Asian river and raising concerns about drinking water and ecosystem health.
