Identification and Characterization of Microplastic Pollutants from the Marine Sediments of Paradeep Coast of Bay of Bengal, India for their Sustainable Management
AI summary Read the abstract
Researchers characterized the abundance, size, color, and polymer types of microplastics in coastal marine sediments along the Bay of Bengal in India, contributing regional data needed to understand how microplastics accumulate on the seafloor and to develop sustainable management strategies for coastal pollution.
One of the serious environmental problems is the abundance and distribution of microplastics which has been identified as a potential factor, especially in oceans and seas. This study reveals MPs abundance, and distribution, based on the colors, size, and polymer...

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.
Microplastic in the Sediment Ecosystem of India
AI summary Read the abstract
This study investigated microplastic accumulation in sediment ecosystems across India, including deep-sea environments, finding widespread contamination across diverse marine habitats. Sediment microplastics are a critical concern because they act as long-term reservoirs that slowly release particles and associated toxins into benthic food webs, ultimately reaching commercially harvested seafood consumed by humans.
