The study provides a health risk assessment for both children and adults, contributing to food safety monitoring efforts.
Detection of microplastics, polymers and additives in edible muscle of swordfish (Xiphias gladius) and bluefin tuna (Thunnus thynnus) caught in the Mediterranean Sea
Researchers detected microplastics — ranging from 140 to 270 particles per kilogram of edible muscle — in swordfish and bluefin tuna caught in the Mediterranean Sea, with polypropylene being the most common polymer type in both species. This confirms that microplastic contamination has reached large, commercially important fish consumed by people across the region.
Heavy metals pollution and health risk assessment in farmed scallops: Low level of Cd in coastal water could lead to high risk of seafood
Researchers tested three species of farmed scallops from China's Bohai and Yellow Seas and found that cadmium (a toxic heavy metal) exceeded safe limits in 96% of samples, posing non-cancer and cancer health risks to both adults and children. The digestive gland accumulated the highest metal levels, and the study recommends limiting whole scallop consumption to no more than 127 grams per week for adults.
Occurrence and Consumer Health Risk Assessment of Heavy Metals in Frozen Demersal Fish and Cephalopod Products from Benoa Port, Bali Province
This study measured heavy metal concentrations in demersal fish and cephalopods landed at Benoa Port in Bali, Indonesia, and assessed the health risks for consumers who regularly eat these seafood products. Several metals were detected at levels warranting attention for frequent consumers, particularly for vulnerable population groups.
The seasonal assessment of heavy metals pollution in the waters of the Mediterranean and Atlantic seas of Morocco
This study measured heavy metal concentrations (Cd, Pb, Zn, Fe, Cu, Cr, Ni) in water samples from both the Mediterranean and Atlantic coasts of Morocco, evaluating seasonal variation in metallic pollution and associated health risks from seafood consumption.
Bioconcentration of Heavy Metals in Milkfish Reared in Stick-Net Pens System: Implications for Open Water Environmental Contamination and Food Safety
Researchers measured concentrations of heavy metals including chromium, cadmium, copper, and lead in both the coastal waters and milkfish meat at stick-net pen cultivation sites in Tanjung Mas, Semarang City, Indonesia. The study assessed bioconcentration of these metals in farmed milkfish and the implications for food safety and open water environmental contamination.
Ecological and health risk assessment of heavy metals bioaccumulation in Ganges fish near Varanasi, India
Not relevant to microplastics — this study measured heavy metal (lead, manganese, chromium, cadmium) contamination in the Ganges River at Varanasi and in fish caught there for human consumption, finding metal levels well above safe drinking water standards and significant bioaccumulation in fish tissue.
Assessment of Essential and Potentially Toxic Elements in Water and Sediment and the Tissues of Sciaena deliciosa (Tschudi, 1846) from the Coast of Callao Bay, Peru
Researchers measured heavy metals in water, sediment, and the tissues of lorna drum fish off the coast of Callao, Peru, finding levels of arsenic, mercury, and lead that exceeded international safety standards in fish muscle. The liver tissue contained even higher concentrations of toxic metals. While focused on heavy metals rather than microplastics, this study is relevant because microplastics can absorb and concentrate these same metals, potentially increasing the toxic burden in fish consumed by coastal communities.
Microplastic Bioaccumulation in Selected Finfish Species Harvested from Northwest Coastal Waters, Sri Lanka: A Potential Risk to Human Health?
Researchers analyzed microplastic bioaccumulation in edible and non-edible tissues of four finfish species from northwest coastal Sri Lanka, finding that 96% of samples were contaminated with particles in the 0.06-0.11 mm range.
