From lake to plate: microplastic occurrence in freshwater fish and multi-index assessment of human exposure in Kaptai Lake, Bangladesh

Evaluation of microplastic presence and risks in freshwater fish from Anzali International Wetland, Iran

AI summary · Read the abstract

Scientists found tiny plastic particles (mostly blue plastic fibers) in the gills and guts of fish from an Iranian wetland, with bottom-feeding fish like tench carrying the most contamination. Since these fish are part of the food chain, and some are likely eaten by people, this suggests microplastics could be working their way up to our dinner plates, highlighting the need for better pollution controls and testing methods to understand the full health risks.

Microplastic Accumulation in Freshwater Fish: Distribution, Sources, and Human Health Implications

Microplastic ingestion and potential risk assessment on commercial and non-commercial marine fish in the Bay of Bengal

AI summary · Read the abstract

Researchers analyzed microplastic contamination in six coral reef fish species from Saint Martin's Island in the Bay of Bengal, finding 100% occurrence rates, with 4-10 microplastics per gastrointestinal tract dominated by polypropylene and polyethylene fibers, and polymer hazard index scores classifying all species in the high-risk 'Danger' category.

Microplastics in Freshwater Ecosystem: Implication for Tropic Transfer, Food Security and Human Health Risk

AI summary · Read the abstract

Researchers reviewed microplastic contamination in freshwater ecosystems, tracing sources from personal care products, synthetic textiles, and wastewater plants, and examining how particles smaller than 5 mm move through trophic levels with implications for food security and human health.

Occurrence of Microplastics in Riverine Fishes Sold for Human Consumption in Chhattisgarh, India

AI summary · Read the abstract

Nearly 88% of riverine fish sampled from six major rivers in Chhattisgarh, India, contained microplastics at an average of 14.9 particles per fish, with the highest contamination near areas of intense municipal waste dumping. This widespread contamination in fish consumed by local populations raises direct human dietary exposure concerns and calls for urgent food safety monitoring in the region.
