Researchers analyzed microplastic contamination in 15 widely consumed dairy products from Bangladesh, including industrial and traditional items. The study found microplastic concentrations ranging from about 1,600 to over 5,100 particles per kilogram, with fibers and polyethylene being the dominant types largely attributed to packaging. Estimated daily intakes varied significantly by age, with children facing higher exposure per body weight than adults.
Integrated analysis of microplastics origins and impact on prominent aquaculture ecosystems in Bangladesh
Researchers surveyed microplastic contamination in aquaculture ponds in Bangladesh, finding widespread particles in both the water and farmed fish including tilapia and pangas. Fibers were the most common type, likely from textile and fishing net waste, and the contamination levels posed potential health risks to consumers. Since farmed fish is a major protein source in Bangladesh and many developing countries, these findings highlight a direct pathway for microplastics to reach people through their diet.
Presence of microplastics in two common dried marine fish species from Bangladesh
Researchers examined two popular dried fish species from Bangladesh and found microplastics present in all samples, with fibers being the most common type. Fish from one collection site had significantly higher microplastic contamination than the other, suggesting location-specific pollution levels. The findings raise concerns about human dietary exposure to microplastics through commonly consumed seafood products in the region.
Microplastic exposure induces muscle growth but reduces meat quality and muscle physiological function in chickens
Researchers found microplastic contamination in chicken muscle tissue from a commercial farm and showed that feeding chickens polystyrene microplastics caused the plastics to accumulate in their muscles over time. While the contaminated chickens grew larger muscles, their meat quality and muscle function decreased. This study is important because it demonstrates that microplastics can build up in poultry meat, meaning people may be consuming microplastics through chicken.
Microplastics in fish culture ponds: abundance, characterization, and contamination risk assessment
Researchers surveyed five types of fish farming ponds in Bangladesh and found microplastics in all sediment and water samples, with higher contamination near industrial areas. The most common microplastics were small fragments and fibers made of polyethylene and polypropylene, likely originating from packaging waste and fishing gear. The findings raise concerns about microplastic contamination in farmed fish that are destined for human consumption.
Microplastic Contamination in Aquafeed Ingredients Used as Protein and Carbohydrate Sources
Researchers analyzed microplastic contamination in common aquafeed ingredients used as protein and carbohydrate sources. They found that poultry by-products had the highest microplastic levels, with polypropylene being a dominant polymer type likely originating from packaging materials. The study identifies a pathway by which microplastics can enter aquaculture food chains through contaminated feed ingredients.
