Abstract Microplastics (MPs) have become an emerging global pollutant due to their widespread dispersion and potential threats marine ecosystems. However, studies on MPs in estuarine coastal ecosystems of Bangladesh are very limited. Here, we conducted the first study abundance, distribution, characteristics, risk assessment microplastics sediment Karnaphuli River estuary, Bangladesh. Microplastic particles were extracted from sediments 30 stations along estuary by density separation then enumerated characterized using a stereomicroscope Fourier Transform Infrared (FT-IR) spectroscopy. In collected number varied 22.29 59.5 items kg −1 dry weight. The mean abundance was higher downstream left banks whereas predominant shape, colour, size films (35%), white (19%), 1–5 mm (30.38%), respectively. Major polymer types polyethylene terephthalate, polystyrene, polyethylene, cellulose, nylon. found pose risks (low high) with highest occurring at one station near sewage outlet, according results analyses pollution index, index (H), contamination factors, load (PLI). single value PLI, clearly demonstrated that all sampling sites considerably polluted (PLI > 1). H values showed toxic polymers, even lower proportions, possess polymeric hazard scores vice versa. This investigation uncovered new insights status laying groundwork for future research control microplastic management.
