Microplastic pollution in the Jamuna River, Bangladesh: Abundance, polymer types, characteristics, and sources in riverbank and riverbed sediments

Original language description

Microplastics (MPs) are pervasive in aquatic environments and pose serious threats to human health, wildlife,and ecosystems. Regional distribution, morphological characteristics, and associated ecological risks of MPsremain poorly understood, particularly in South Asia. The Jamuna River, one of Bangladesh’s largest freshwatersystems, is increasingly affected by microplastic contamination, likely stemming from diverse point and nonpointsources. This study systematically investigated and compared the distribution, characterization, andecological risk of MPs in riverbank and riverbed sediments of the Jamuna River. Surface sediments werecollected from 20 sites along a 44-km transect across the Tangail and Sirajganj districts. Our results showed thatriverbed sediments contained a higher concentration of MPs (484 ± 96 MPs/kg) compared to riverbank sediments(332 ± 98 MPs/kg). Despite the difference in abundance, both sediment types showed similar morphometricprofiles, dominated by fibrous particles, black fragments, and particles &lt; 500 μm. The identified polymersincluded polyethylene (PE), polyethylene terephthalate (PET), polypropylene (PP), polystyrene (PS), and polyvinylchloride (PVC), with PE being the most prevalent. The polymer hazard index (PHI) classified both sedimenttypes under risk level IV (high hazard), while the potential ecological risk index (PERI) placed them in riskcategory V (extreme danger). These findings highlight the critical need for continuous monitoring and theimplementation of effective regulatory measures to mitigate microplastic pollution in Bangladesh’s river systems.
