Microplastic pollution along the coastal island shorelines of Bangladesh: Distribution, patterns, and abundance
Microplastics (MPs), less than 5 mm in length, have become a major environmental issue due to their hazardous physical and chemical properties. The research investigated 54 sediment samples collected from three different zones of the beaches, namely the wrack line, beach face, and swash zone. This s...

| description | Microplastics (MPs), less than 5 mm in length, have become a major environmental issue due to their hazardous physical and chemical properties. The research investigated 54 sediment samples collected from three different zones of the beaches, namely the wrack line, beach face, and swash zone. This study aims to enumerate the number and polymeric variety of microplastics found in beach sediments from coastal islands of Bangladesh, including Sandwip, Kutubdia, and Saint Martin's Island in the northeastern Bay of Bengal. NaCl solution with the density of 1.2 g/cm3 was used as a density-separating solvent. Microplastics were extracted using conventional protocols, yielding an average of 193 ± 68.9, 175.5 ± 63.1, and 266.3 ± 232 particles per kg from the collected samples of Sandwip, Kutubdia, and Saint Martin's Island respectively, with five morphotypes: fiber, film, fragment, foam, and pellet, where fiber dominated each island. White microplastics were most spread in both Sandwip and Saint Martin's Island, whereas translucent and blue were most abundant in Kutubdia. Moreover, polypropylene (PP) was shown to be the greatest number of polymer groups among those analyzed microplastic particles using ATR-FTIR (Attenuated total reflectance-Fourier transform infrared) spectrometer. Using scanning electron microscopy (SEM), it was also possible to detect surface degradation, rupture, or fracture that was probably caused by the environment. The study emphasizes the critical need for continued research and monitoring to better understand the dynamics of microplastic pollution and its long-term impacts. By tackling the underlying causes and implementing effective management practices, we can achieve a cleaner and more sustainable future for coastal communities and marine ecosystems. |
