ClearEvaluation of genotoxic and mutagenic potential of polystyrene nanoplastics in forked venus clam, Gafrarium divaricatum (Gmelin, 1791)
Researchers evaluated the genotoxic and mutagenic effects of polystyrene nanoplastics on an intertidal clam species over exposure periods of 96 hours and 15 days. They found significant time- and concentration-dependent DNA damage, micronuclei formation, and altered expression of stress and DNA repair genes in gill and intestinal tissues. The study demonstrates that nanoplastics can cause genetic damage in marine bivalves, raising concerns about their ecological impact.

Researchers exposed clams to nanoplastics at concentrations found in real marine environments and tracked how the particles accumulated in their tissues over 14 days. The nanoplastics caused physical damage and significantly altered the clams' gut bacteria. This is concerning because clams are widely consumed seafood, meaning nanoplastic contamination could affect both marine ecosystems and human food sources.
