The study identifies these coastal estuaries as accumulation zones for microplastic pollution, posing risks to local aquatic life and fishing communities.
Driving aspects of microplastic uptake: Influence in the Bentho-Pelagic ecosystem and its associated ecological risks along the coast of Goa, India
Researchers studied microplastic contamination in nine fish and shellfish species along the coast of Goa, India, to understand how habitat and feeding behavior drive microplastic ingestion. Benthic organisms and sediments showed higher contamination than pelagic species and water, with fibrous polyamide and polyester particles being most abundant, and the Polymer Hazard Index indicated considerably high risk for certain polymers found in these food species.
The extent of microplastic pollution along the eastern coast of India: Focussing on marine waters, beach sand, and fish
Researchers assessed microplastic contamination across water, sand, and fish from seven major beaches along India's eastern coast, finding widespread pollution dominated by polyethylene and polystyrene with hazard indices indicating potential ecological risk.
Accumulation of microplastic in edible marine species from North Kerala, India
Researchers found microplastics in the edible tissues of three popular seafood species (clams, shrimp, and anchovies) from fish markets in Kerala, India. Fibers and fragments were the most common shapes, with polyethylene and polypropylene being the dominant plastic types. Since these species are consumed whole or with minimal processing, the study highlights a direct pathway for microplastic ingestion by people who eat locally caught seafood.
