AB  - Current work focus on microplastic (MPs) occurrence in the water, sediment, and 
      aquatic species (fish, crab, and snail) of the Buriganga River, Bangladesh, with 
      an ecological risk assessment perspective. It also includes the distribution of 
      MPs in different river ecosystem segments and the presence of heavy metal (loid)s 
      (HMs) in water, sediments, and MPs surface. The MPs were inspected by 
      stereomicroscope to identify the shapes, color, and size, and Fourier transform 
      infrared (FTIR) spectroscopy was used to characterize polymer types. The samples 
      concentration of four HMs viz., As, Cd, Cr, and Pb were determined by atomic 
      absorption spectrometry (AAS). The possible MPs content in water, sediment, fish, 
      crab, and snail were varied from 0.250 to 0.117 MPs/mL, 3.5-8.17 MPs/g, 0.65-3.82 
      MPs/g, 3.75-4.28 MPs/g, and 0.84-1.12 MPs/g, respectively. Fibers and fragments 
      were the most dominant shape, less than 0.5 mm was dominant in size, and blue was 
      the dominant color. In the evaluation of the chemical composition of MPs in 
      water, sediment, fish, snail, and crab samples, Polyethylene terephthalate 
      (PETE), Ethylene-vinyl acetate (EVA), High-density polyethylene (HDPE), 
      Acrylonitrile butadiene styrene (ABS), Cellulose acetate (CA), and Nylon were 
      identified. Regarding HMs load, the river demonstrated a highly polluted 
      environment following the abundance pattern Cr > Pb > As>Cd. SEM-EDAX of MPs was 
      conducted to investigate the surface MP's surface and elemental composition. It 
      reveals that the MPs surface has characteristic flakes, cracks, and adhering 
      particles along with Si, K, Au, C, and O on the surface studied MPs. There is no 
      significant relationship found among the ecosystem segments. However, Ompok 
      bimaculatus species show a negative relationship of MPs distribution with water 
      and sediment. Moreover, according to the ecological risk of MPs pollution in the 
      Buriganga River, it was in category-I, indicating considerable pollution load due 
      to the presence of MPs.
