Assessment of Human Activities as Drivers of Microplastic Pollution in Rural and Urban Water Bodies | Kashf Journal of Multidisciplinary Research

Abstract Microplastic contamination of inland waters is increasingly understood as a consequence of ordinary human production, consumption, disposal, and land-management practices. This article assesses how domestic waste handling, wastewater discharge, textile use, agricultural plastics, traffic-related deposition, recreation, and the fragmentation of larger plastic litter shape microplastic loads in rural and urban water bodies. It integrates current conceptual evidence with primary findings reported in Hamza Khalil’s thesis on twelve water sites in Tehsil Pattoki, Punjab, Pakistan. The thesis used filtration, sodium-chloride density separation, drying, and stereomicroscopic observation at 40× magnification. Site-level reconstruction from the thesis tables identified microplastics at four locations: an urban swimming pool (6 MPs/L), an urban canal (10 MPs/L), a rural standing surface-water site (12 MPs/L), and an urban standing swamp-water site (15 MPs/L); eight filtration-plant, drinking-water, drain/nullah, and tap-water samples recorded zero particles. The overall mean was 3.583 MPs/L. When site values are paired with the distribution-area labels in the sampling table, the six urban sites total 31 MPs/L (mean 5.17), while the six rural sites total 12 MPs/L (mean 2.00). The thesis reports no statistically significant group difference (F = 0.93, p = 0.35), so the observed contrast must be interpreted cautiously. Results nevertheless suggest that open, stagnant, recreational, and canal waters are more exposed to direct human inputs than protected groundwater-derived supplies. The article argues that source control, drainage management, wastewater improvement, agricultural plastic recovery, and harmonized monitoring are more effective than downstream cleanup alone
