Characterization and risk assessment of microplastics pollution in Mohamaya Lake, Bangladesh
AI summary Read the abstract
Researchers characterized microplastic pollution in Mohamaya Lake, Bangladesh, finding concentrations of 20-95 particles per liter in water and 550-1,900 particles per kilogram in sediment. The most common types were fibers and fragments made of polyethylene and polypropylene, likely from fishing activities, tourism, and nearby urban areas. The study's risk assessment indicates that microplastic levels in some areas of the lake could pose ecological risks to aquatic life and potentially to the communities that use the lake for water and food.
Microplastics (MPs) have recently gained attention as emerging environmental contaminants, yet knowledge of their distribution, sources, and risks in freshwater lakes remains limited. This study examined the occurrence and risk of MPs in water and sediment samples from eight locations in Mohamaya Lake (Bangladesh) collected in April and May 2023. MPs were identified using stereomicroscopy and FTIR, revealing concentrations of 20-95 particles/L in water and 550-1900 particles/kg (d.w.) in sediment, with mean values of 50.62 ± 9.95 particles/L and 1068.75 ± 521.49 particles/kg (d.w.). Dominant MPs were blue fibers, 0-0.5 mm in size, with HDPE, PET and LDPE as the most common polymers. This study used four indices (nemerow pollution index-NPI, contamination factor-CF, pollution load index-PLI, and polymer hazard index-PHI) to assess MP pollution, revealing light to high contamination levels. While NPI indicated light pollution, CF, PLI, and PHI highlighted areas of moderate to high risk, with certain polymers showing high to extreme toxicity. This study deepens understanding of MP contamination in Bangladesh's freshwater lakes, underscoring the need for research on ecotoxicology, regulation, and associated challenges.

Abundance and characteristics of microplastics in major urban lakes of Dhaka, Bangladesh
AI summary Read the abstract
Researchers measured microplastic contamination in three major urban lakes in Dhaka, Bangladesh, finding plastic particles in the water, sediment, and fish at all sites. The dominant plastics were common consumer types like polyethylene and PVC, with sizes mostly under 100 micrometers. Since these lakes are in a densely populated urban area, the findings raise concerns about microplastic exposure for the local population through both water and fish consumption.

Occurrence and spatial distribution of microplastics in water and sediments of Hatiya Island, Bangladesh and their risk assessment
AI summary Read the abstract
Researchers assessed microplastic distribution in surface water and sediments around Hatiya Island, Bangladesh, finding higher contamination in sediments than in water. Fibers were the most common type, and polymer analysis identified potentially hazardous plastics including polyurethane, polycarbonate, and polyvinyl chloride. While basic pollution indices showed minimal levels, hazard-based risk assessments indicated severe contamination due to the presence of these hazardous polymer types.
