ClearInvestigating a probable relationship between microplastics and potentially toxic elements in fish muscles from northeast of Persian Gulf
Researchers measured microplastic and metal concentrations in the muscles of benthic and pelagic fish species from the northeastern Persian Gulf. They found that microplastic and mercury levels increased with fish size, and estimated that consuming moderate portions of fish weekly provides essential nutrients without significant health risk. The study suggests that while fish remain a beneficial food source, monitoring microplastic and metal co-contamination in seafood is important for consumer safety.
Characterization of plastic debris and association of metals with microplastics in coastline sediment along the Persian Gulf
Microplastics and sediment samples from Persian Gulf coastlines were found to contain elevated concentrations of heavy metals including lead, cadmium, and mercury, with metals associated with both the plastic surfaces and the surrounding sediment. The study demonstrates that microplastics in this industrialized coastal region accumulate hazardous metals that can be transferred to marine organisms.
Source and risk assessment of heavy metals and microplastics in bivalves and coastal sediments of the Northern Persian Gulf, Hormogzan Province
Researchers assessed heavy metal contamination and microplastic distribution in coastal sediments and edible bivalves from the northern Persian Gulf in Hormozgan Province. They found varying levels of both pollutant types across sampling sites, with proximity to industrial and urban areas correlating with higher contamination. The study provides a risk assessment indicating that combined exposure to heavy metals and microplastics through seafood consumption in the region warrants monitoring.
Investigating microplastics bioaccumulation and biomagnification in seafood from the Persian Gulf: a threat to human health?
Researchers investigated microplastic bioaccumulation and biomagnification in five commercially important seafood species from the Persian Gulf, examining both muscle tissue and gills.

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.
Microplastics and trace metals in fish species of the Gulf of Mannar (Indian Ocean) and evaluation of human health
Researchers examined microplastics and trace metals in five commercially important fish species from the Gulf of Mannar in the Indian Ocean. They found microplastics in both muscle and intestinal tissues, predominantly polyethylene and polypropylene particles, and estimated that human consumers could ingest 121 to 456 microplastic items per person per year from eating these fish.
Potentially toxic elements and microplastics in muscle tissues of different marine species from the Persian Gulf: Levels, associated risks, and trophic transfer
Researchers analyzed potentially toxic elements and microplastics in the muscle tissue of various seafood species from the Persian Gulf. They found high levels of both contaminants in crustaceans, with arsenic posing the greatest cancer risk to consumers. The study indicates that biomagnification occurs for certain contaminants through the marine food web, raising concerns about the combined health risks of heavy metals and microplastics in seafood.
Assessment of microplastics in the gastrointestinal tract of some fish caught for human consumption in Bandar Abbas, the Persian Gulf
Researchers examined microplastic content in the digestive tracts of fish caught for human consumption in the Persian Gulf near Bandar Abbas, Iran. Microplastics were found in multiple commercially important species, with the highest contamination rates in Sillago sihama (62%), raising food safety concerns for local seafood consumers.
