“…reported MP quantities ranging from 22.29 to 59.5 items per kilogram (kg) based on dry weight in the sediment of the Karnaphuli River estuary. This investigation focused exclusively on MP abundance in sediment, whereas the present study examined MPs in surface water Hossain et al (2023). found a range of MP concentrations from 33.33 to 316.67 items/m³, with a mean value of 128.89 ± 67.94 items/m³ in the Meghna River estuary in Bangladesh Islam et al (2022).…”

“…Recent studies have uncovered the occurrence of MPs in diverse marine and freshwater environments throughout the country (Rezania et al, 2018). Significant level of MP abundance was found in the Meghna River estuary (Hossain et al, 2023), Buriganga River (Islam et al, 2022), and Pasur River in Bangladesh (Nawar et al, 2023). The Karnaphuli River, which originates in Mizoram state, India, holds immense significance for navigation, fishing, transportation, and industrial activities in Chattogram City and the hill tracts regions of Chattogram, Bangladesh (Siddique & Akter, 2012).…”

Microplastic (MP) pollution in aquatic environments is a growing concern worldwide. This study investigated the abundance, types, and attributes of MPs in the surface water at two industrial sites (Avoimitro Ghat and Kalurghat) along the Karnaphuli River in Chattogram, Bangladesh. Sampling was conducted over eight months across three transects encompassing a total area of 500 m at each site. A manta net of 200 μm mesh size was used to sample MPs. The obtained samples were subsequently filtered, enumerated, and characterized using a stereo microscope and imaging software. The mean abundance of MP particles (per km 2 ) was found higher in Avoimitro Ghat (94,861 ± 57,126) than in Kalurghat (31,343 ± 23,183). A significant statistical difference (p < 0.05) was observed in the mean abundance of MP particles between the wet and dry seasons. The fragment group of MP exhibited the most abundant category, whereas the pellet category displayed the lowest. MPs with an elongated shape prevailed at both locations throughout all seasons. At Avoimitro Ghat, blue-colored MPs demonstrated the highest mean count, while in Kalurghat, the highest mean count belonged to brown-colored MPs. The size distribution of MPs differed between the two sites, with 1-2 mm MPs being plentiful in both seasons and Avoimitro Ghat, whereas MPs ranging from 500 µm to less than 1 mm were abundant in Kalurghat. Ten (10) polymer types were found from Fourier-transform infrared spectroscopy (FTIR) analysis with high levels of polypropylene atactic in both Avoimitro Ghat (32%) and Kalurghat (17%). The findings provide important insights into MP pollution in the Karnaphuli River, which may aid in developing effective strategies to mitigate the impacts of MP pollution on the aquatic ecosystem and human health.

“…MPs can be divided into two categories. Virgin pellets of pharmaceutical, cosmetic, or personal care items (glitters and microbeads) and cleaning products in the plastics industry are the primary types of MPs (Hossain et al, 2023a). Through processes of degradation or fragmentation, secondary MPs are created from bigger plastic debris (Barnes et al, 2009;Andrady, 2011).…”

Microplastics (MPs), an emerging pollutant, have drawn attention on a global scale and have been found in various ecosystems. Nevertheless, there is currently a lack of information regarding the contamination levels of MPs in aquaculture ponds worldwide. In this study, sediment and water samples were collected from five types of fish ponds, namely, homestead ponds (S1), commercial aquaculture ponds (S2), ponds near a residential area (S3), ponds near a small-scale industrial area (S4), and ponds near a large-scale industrial area (S5), to identify, characterize, and assess the contamination risk of MPs. Stereomicroscopic and Fourier-transform infrared (FTIR) spectroscopy analyses revealed that the MPs ranged from 3.33 item/kg to 136.67 item/kg in sediment and 16.6 item/L to 100 item/L in water samples. Overall, the abundance of MPs was extremely high in S5, followed by S4, S2, S3, and S1, which clearly showed the levels increased with the intensity of human activities. The levels of MPs in both sediment and water showed significant differences (p < 0.05) within and between ponds, as well as in comparison between water and sediment samples. The concentrations of MPs surpassed those noted in aquaculture ponds of different nations. The majority of MPs consisted of fragments and films in both sediment and water samples. Furthermore, transparent and white-colored MPs were the prevailing types found in the sediment and water samples of the aquaculture ponds. Around 34% of MPs present in sediment and 30% in water fell within the size range of 0.5–1 mm. Polymers like polypropylene (PP), polyethylene (PE), and polyethylene terephthalate (PET) were prevalent in both sediment and water samples. The contamination factor reached exceptionally elevated levels (>30 for sediment and >3 for water), signifying that the sampled regions, particularly S4 and S5 (industrial sites), displayed significant MP contamination. Moreover, the pollution load index values of the sediment (3.0 ± 1.5) and water samples (1.5 ± 0.3) also indicated the areas were contaminated with MPs. Multivariate analysis indicated that the elevated concentration of MPs in the studied region could be attributed to the discharge of effluents and other human-induced activities.
