ClearRisk assessment and influence of microplastics on mangrove forest soil: Sandwip Island, Chittagong, Bangladesh
Researchers assessed microplastic contamination in mangrove forest soils on Sandwip Island, Bangladesh, characterizing the abundance, types, and potential ecological risks of the particles. They found notable levels of microplastic pollution in the mangrove sediments, with fibers and fragments being the most common forms. The study highlights an understudied threat to mangrove ecosystems and calls for greater attention to microplastic impacts on these critical coastal habitats.
Risk assessment of microplastic pollution in an industrial region of Bangladesh
Scientists assessed microplastic pollution in industrial soil from Narayanganj, Bangladesh, finding contamination in all 12 samples tested, with fibers being the most common particle type. A pollution risk assessment classified the area as having a moderate to high level of microplastic contamination. This study highlights how industrial regions in developing countries face significant microplastic soil pollution that could affect nearby communities through dust, water, and locally grown food.
From beaches to mangroves: Spatiotemporal mapping and risk profiling of microplastics in coastal Bangladesh
A comprehensive survey of microplastic contamination along the entire coastline of Bangladesh found plastic particles at all 18 sampling sites during both monsoon and winter seasons, with polypropylene, polyethylene, and polystyrene making up the majority of the material. Concentrations averaged 385–471 particles per 100 grams of sediment, and ecological risk assessments classified most sites as ranging from "danger" to "extreme danger" for marine life. Bangladesh's densely populated and heavily plastic-polluted coast represents a serious environmental hotspot requiring urgent monitoring and management.
Spatial distribution and ecological risks of microplastics in agricultural soils near a solid waste dumpsite in southwest Bangladesh
Researchers assessed microplastic contamination in agricultural soils surrounding a municipal solid waste dumpsite in southwest Bangladesh, characterizing the types, spatial distribution, and ecological risks. They found significant microplastic accumulation in soils near the dump, with contamination levels decreasing at greater distances. The study highlights that waste dumpsites are important point sources of microplastic pollution that can affect the fertility and ecological health of surrounding agricultural lands.

Researchers investigated microplastic pollution in the Moheshkhali channel of the Bay of Bengal and found significant contamination in both sediments and surface water, with pollution load indices indicating serious environmental concern.
Current scenario and challenges of plastic pollution in Bangladesh: a focus on farmlands and terrestrial ecosystems
Researchers reviewed the sources, dispersion routes, and environmental consequences of plastic waste across global and Bangladesh-specific contexts, finding that inadequate infrastructure and limited resources make plastic pollution — including microplastics entering agricultural soils, marine environments, and food chains — an especially acute threat in developing countries.
Microplastics in beach sediments of the Northern Bay of Bengal, Bangladesh: Insights into occurrence, distribution, pollution indices, and ANN-based risk modeling
Researchers investigated the occurrence, abundance, distribution, and risk of microplastics in beach sediments at two Bangladeshi coastal sites — Cox's Bazar and Kuakata — finding widespread contamination and raising concern about microplastic pollution in the Northern Bay of Bengal.
Microplastic Pollution in Bangladesh: A Review of Ecological and Biochemical Impacts
This review summarized the current state of microplastic pollution in Bangladesh, covering occurrence across water, soil, seafood, and air, as well as documented ecological and biochemical health impacts. The authors identify Bangladesh's rapid urbanization and poor waste management as key drivers of its disproportionate microplastic burden.
Microplastics contamination in the soil from Urban Landfill site, Dhaka, Bangladesh
Researchers assessed microplastic contamination in soil samples from an urban landfill site in Dhaka, Bangladesh. They found microplastics in all samples, predominantly fibers and fragments made of polyethylene and polypropylene, with concentrations varying across the landfill. The study provides some of the first evidence of terrestrial microplastic pollution in Bangladesh and identifies urban landfills as significant reservoirs of soil microplastic contamination.
Widespread microplastic pollution in mangrove soils of Todos os Santos Bay, northern Brazil
Researchers found widespread microplastic pollution in mangrove soils around Todos os Santos Bay in Brazil, detecting contamination at multiple depths and distances from the tidal area, highlighting mangroves as previously overlooked sinks for microplastic accumulation.
Microplastic Contamination of Non-Mulched Agricultural Soils in Bangladesh: Detection, Characterization, Source Apportionment and Probabilistic Health Risk Assessment
Researchers found microplastics in agricultural soil across Bangladesh at all depths tested, even though the fields did not use plastic mulch film. Eight different plastic types were identified, with concentrations varying by location, and coastal areas had the highest levels. The study suggests that irrigation water and organic fertilizers are introducing microplastics to farmland, potentially entering the food chain through crops grown in contaminated soil.
Distribution characteristics of microplastics in the soil of mangrove restoration wetland and the effects of microplastics on soil characteristics
Researchers measured microplastic distribution in soils of a mangrove restoration wetland with different planting densities, finding an average abundance of 217 MPs per kilogram of dry soil with higher concentrations in denser planting zones. MPs in the soil also altered wetland soil physicochemical properties including bulk density and organic matter content.

Microplastic in mangroves: A worldwide review of contamination in biotic and abiotic matrices
This worldwide review analyzed 53 studies on microplastic contamination in mangrove sediments, water, and organisms across Asia, America, and Africa, finding that research is geographically limited and lacks wide-scale coverage of mangrove coastlines. Most studies characterized microplastic type, size, color, and morphology but did not assess ecological risks.
