Characterisation and distribution of microplastics in the inner shelf sediments of the southeast coast of India, Bay of Bengal
AI summary Read the abstract
Researchers sampled seafloor sediments along India's southeast coast in the Bay of Bengal and found widespread microplastic contamination, documenting the types, shapes, and chemical makeup of the particles. The findings reveal how plastic pollution is building up in coastal marine sediments that support fisheries and local food supplies.
Assessment of spatial distribution, sources, and ecological risks of microplastics in the estuarine and coastal regions of the northern Bay of Bengal
AI summary Read the abstract
Surveys of the northeastern Bay of Bengal found surface water MP concentrations up to 1,640 items/m³ in the Karnaphuli estuary, dominated by fiber-shaped polypropylene particles, with pollution risk indices ranging from medium to very high across estuarine and coastal zones. The high MP burden in this densely populated coastal region poses serious risks to marine biodiversity, local fisheries, and the millions of people who depend on Bay of Bengal seafood as a dietary staple.
Microplastics and mesoplastics in surface water, beach sediment, and crude salt from the northern Bay of Bengal, Bangladesh coast
AI summary Read the abstract
Researchers quantified microplastics and mesoplastics across surface water, beach sediments, and crude sea salt from the Cox's Bazar coast of Bangladesh, finding up to 630 microplastic items/kg in crude salt and widespread contamination across all environmental matrices. The presence of substantial microplastics in crude sea salt is particularly significant because salt is a dietary staple consumed globally, providing a direct route for plastic particle ingestion by human populations.

A critical review of the emerging research on the detection and assessment of microplastics pollution in the coastal, marine, and urban Bangladesh
AI summary Read the abstract
Researchers reviewed emerging studies on microplastic pollution in Bangladesh, finding contamination across coastal beaches, marine fish, and urban environments tied to tourism and fishing activities, and highlighting the urgent need for health impact assessments and pollution-reduction policies in rapidly developing nations.
