Microplastic (MP) contamination in freshwater systems is a prevalent and persistent environmental issue, yet their occurrence distribution remain poorly constrained. The present study examines the MPs abundance sediment water samples factors controlling Manasbal Lake, north-western (NW) Himalaya. Additionally, investigates relationship between heavy metals of sediment, as well potential interactions. counts lake surface varied from 840 nkg−1 to 4020 13 nL−1 89 nL−1, respectively. Lake exhibited spatial heterogeneity, with greatest observed eastern northeastern areas near inlets. Grain size land use appear collectively modulate variability sediments. Five main types were identified: beads/pellets, fragments, fibres, foams, films, beads being predominant type. Polypropylene, polyethylene, polystyrene are dominant constituents MPs, domestic sewage suggested source for lake. Furthermore, factor indicated high level lead sediments, while copper cobalt showed moderate inlet. SEM-EDS analysis illustrated presence toxic elements such Hg, Zn, Pb, Cr, Cd, Ni, Cu MPs. This expands baseline characterization enhances our understanding sources influencing MP distribution.

Abstract Microplastic (MPs) pollution has engulfed global aquatic systems, and the concerns about MPs translocation bioaccumulation in fish, crabs, other marine organisms are now an unpleasant truth. In past few years, freshwater particularly rivers, subsequently organisms, especially caught attention of researchers. Rivers provide livelihood to approximately 40% population through food potable water. Hence, assessment emerging contaminants like waterways associated fauna is crucial. This study assessed crab S. serrata across largest riverine system south India, Kaveri River. The were characterized by optical microscopy, field emission scanning electron microscopy‐energy dispersive X‐ray (FESEM–EDX) analysis for their number, shape, size, color. Polymer composition was analyzed using attenuated total reflectance Fourier‐transform infrared spectroscopy (ATR‐FTIR) Raman spectroscopy. Polypropylene (PP), polystyrene (PS), polyamide (PA), polyvinyl chloride (PVC) dominant plastic polymers intestine. Additionally, FE‐SEM revealed that have differential surface morphology with rough surfaces, porous structures, fissures, severe damage. Most comprised Na, Si, Mg, Cl, K, Ca, according EDX analyses. findings might insight into status at Kavery river could help formulating regulations reduction contamination rivers eventually protect environment human health. Practitioner Points first on identity properties crabs from River Mettur Dam. A simple cost‐effective approach extracting microplastics samples Dam, River, Salem District, Tamil Nadu, India. Microplastics detected ATR‐FTIR, FE‐SEM.
