Occurrence, characteristics and distribution of microplastics in commercial marine fishes of the Bay of Bengal
Scientists found microplastics in the muscles, guts, and gills of six commercially important fish species from the Bay of Bengal, identifying over 7,000 particles total. Polyethylene and polypropylene fibers were the most common types, and tuna had the highest contamination levels. Since these fish are widely consumed by people in the region, the findings highlight a direct dietary exposure pathway for microplastics to reach humans through seafood.
Microplastic contamination in commercial fish species in southern coastal region of India
Researchers examined 220 commercial fish from the southern coast of India over six months and found microplastic contamination in all samples, with an average of 3.2 to 7.6 particles per fish. The most common types were fibers and fragments, primarily composed of polyethylene, polypropylene, polystyrene, and polyamide. The findings indicate that microplastic contamination in commercially valuable fish species is widespread along the Indian coast, raising concerns about food safety.
