The findings raise public health concerns about microplastic exposure through freshwater fish consumption in densely populated urban areas.
Abundance, characteristics, and risk assessment of microplastics in indigenous freshwater fishes of India
Researchers examined microplastic contamination in five widely consumed freshwater fish species from India and found plastic particles in all specimens, with fibers being the most dominant type. Evidence of microplastics in edible fish tissue indicates translocation from the gut, suggesting a pathway for human exposure through consumption. Risk assessment showed that while microplastic abundance posed a low quantitative risk, the polymer types identified indicated a high hazard potential for the fish species studied.
Microplastic Contamination in Edible and Inedible Tissues of Labeo rohita Across Rajasthan and Haryana: A Comparative Assessment
Researchers analyzed microplastic contamination in edible (muscle and skin) and inedible (gut and gills) tissues of freshwater rohu fish (Labeo rohita) from 10 locations in Rajasthan and Haryana, India. MPs were found in all tissue types, including muscle and skin consumed by humans, indicating a food safety concern in these regions.
Microplastic Occurrences in Freshwater Fish of Bangladesh
This review synthesizes research on microplastic contamination found in freshwater fish across Bangladesh, where rapid population growth and urbanization have led to significant plastic pollution. Researchers found that fibers are the most commonly detected microplastic type in fish tissues, raising concerns about impacts on gut health and immune function. The study highlights the need for more comprehensive monitoring given Bangladesh's heavy reliance on freshwater fish as a dietary staple.
Investigation of Microplastic Accumulation in Two Freshwater Fish Species (Labeo rohita and Wallago attu) from Tanguar Haor, Bangladesh
Researchers extracted and identified microplastics from the stomach, intestine, and dorsal muscle of Labeo rohita and Wallago attu from Tanguar Haor wetland in Bangladesh, confirming PP, PE, PVC, PA, PET, and PMMA via FTIR, UV-visible, and SEM/EDS. The intestine contained the most diverse range of polymer types, and the smallest microplastic mean diameter (570 nm) was found in dorsal muscle of Labeo rohita.
Effects of Micro Plastics on Fishes of Hooghly River, India
A study of fish in the Hooghly River near Kolkata found microplastic particles (0.3–5 mm) in multiple species and in riverbank sediments, with fiber and fragment shapes causing visible damage to fish livers and gills. The river receives plastic waste from surrounding urban land, making it a conduit for contamination into the fish that local communities consume. Organ damage in fish from microplastic ingestion raises broader concerns about food safety and ecosystem health in densely populated river systems.
Characterization of microplastics in commercially valued Gangetic fishes and its exposure assessment on humans
Researchers characterized microplastics in commercially sold fish from the Ganges River in India, finding plastic contamination across multiple species and providing an initial exposure assessment for human consumers who rely on freshwater fish as a primary protein source.
Effect of plastic microbeads on the development of roho (Labeo rohita)
Researchers fed roho fish (Labeo rohita) varying doses of plastic microbeads over 120 days and found that ingesting microplastics directly stunted their growth, with higher concentrations causing greater harm — providing evidence that microplastic pollution can impair the health of freshwater fish species.
Effects of microplastics in freshwater fishes health and the implications for human health
This review examines how microplastics affect the health of freshwater fish, which are a major protein source for billions of people. Fish ingest microplastics that accumulate in their guts, gills, and tissues, leading to inflammation, oxidative stress, and disrupted growth. Since microplastics in fish tissue can transfer to humans through the food chain, this is relevant to both ecosystem and human health.
