Abstract	Microplastic pollution has emerged as a significant environmental concern due to its persistence, widespread occurrence, and adverse ecological impacts on freshwater ecosystems. The present study investigates the occurrence, distribution, and characteristics of microplastics and examines their relationship with physicochemical water quality parameters in the Shivnath River, Chhattisgarh, India. Water samples were collected from representative upstream, midstream, and downstream locations covering agricultural, urban, and industrial regions. Physicochemical parameters including pH, temperature, electrical conductivity (EC), total dissolved solids (TDS), dissolved oxygen (DO), biological oxygen demand (BOD), chemical oxygen demand (COD), turbidity, nitrate, phosphate, chloride, sulphate, and total hardness were analyzed using standard methods. Microplastics were isolated through density separation, filtration, oxidative digestion, microscopic examination, and Fourier Transform Infrared Spectroscopy (FTIR) for polymer identification. The study revealed considerable spatial variation in microplastic abundance, with higher concentrations observed near densely populated and industrialized areas. Polyethylene (PE), polypropylene (PP), polystyrene (PS), polyethylene terephthalate (PET), and polyvinyl chloride (PVC) were identified as dominant polymers. Statistical analyses demonstrated significant positive correlations between microplastic abundance and EC, TDS, turbidity, BOD, COD, nitrate, and phosphate, while dissolved oxygen exhibited a negative correlation. The findings indicate that anthropogenic activities strongly influence both microplastic contamination and overall river water quality. The study provides valuable baseline information for environmental monitoring and supports the development of sustainable management strategies for freshwater ecosystems.
