ClearThe effect of different types of microplastic and acute cadmium exposure on the Mytilus galloprovincialis (Lamarck, 1819)
This study examined how different types of microplastics, alone and combined with cadmium, affect Mediterranean mussels that are widely consumed as seafood. Exposure to microplastics and cadmium caused oxidative stress, tissue damage, and neurotoxicity in the mussels, with combined exposure being worse than either pollutant alone. The health risk calculations for human consumers exceeded safety limits, suggesting that microplastic-contaminated mussels could pose a real food safety concern.
