Description
Summary:•Micropolystyrene (100 nm) shows morpho, cytogenotoxic effects in Allium cepa.•MPS acts in both time and dose dependent manner.•Induces ROS production, chromosomal abnormalities and lowers cdc2 expression.•Provides new insights about how MPS affects the terrestrial system. Plastic pollution represents a global concern for the biodiversity conservation, ecosystem and public health. The polystyrene is one of the dominant pollutants in both terrestrial and aquatic ecosystem. This work measured the hazardous nature of 100 nm micropolystyrene (MPS) using 25, 50, 100, 200, and 400 mg/L concentrations in terms of oxidative stress, morphotoxicity and cytogenotoxicity in Allium cepa. The results were compared with the positive control (PC) (400 mg/L chlorpyrifos). MPS significantly (p
