Microplastics Lead to Hyperactive Swimming Behaviour in Adult Zebrafish

Microplastic pollution has drawn the attention of both scientists and the public regarding their potential ecotoxicological risks. In the present study, we carried out aqueous exposure experiments to adult zebrafish with polystyrene microplastics (5 μm) at a wide range of concentrations (0.001-20 mg/L, equals to 14.5∼2.9 × 105 particles/mL). Our results showed the gastrointestinal tract (GIT) was the dominant microplastic accumulation site in...
