Nanoplastics amplify 6PPD ocular toxicity in zebrafish.

ABSTRACT: Nanoplastics and tire-derived chemicals are ubiquitous co-pollutants in aquatic environments, originating from road runoff and posing potential risks to vertebrate development through enhanced bioavailability and synergistic toxicity. Polystyrene nanoplastics (PS) can adsorb hydrophobic organics like the antioxidant N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD), acting as vectors that increase tissue accumulation and exacerbate oxidative stress, while 6PPD alone disrupts mitochondrial function and induces sublethal effects in exposed organisms. The vertebrate eye, with its direct environmental exposure and sensitive neural structures, is particularly vulnerable, yet the combined impact of PS and 6PPD on visual morphogenesis remains underexplored. Here we show that co-exposure t
