This study focused on the distribution of microplastics in the water and sediment of the Ganges River Basin to the Meghna Estuary in Bangladesh. Thirty points were sampled from Chapainawabganj district (India-Bangladesh border) to Chandpur district (Meghna Estuary). The morphological appearances were recognized by stereomicroscope and SEM-EDX analysis. Potential ecological risks were also measured. The average microplastic concentration in upstream and downstream water was 50.9 ± 24.4 particles/L and 64.1 ± 26.3 particles/L, respectively, and the sediment concentration was 2953.49 ± 1670.52 particles/kg in upstream sediment and 4014.66 ± 1717.59 particles/kg in downstream sediment. In upstream water, the most dominant morphological appearance was fragment shape, blue colour and 1–2 mm in size. The appearance of downstream water was fragments shape, red colour and 0.1–0.5 mm in size. In upstream sediment, the most dominant morphological appearance was fragment shape, red colour and |
