The Biological Effects of Polystyrene Nanoplastics on Human Peripheral Blood Lymphocytes.

Environmental exposure to microplastics (MPs) and nanoplastics (NPs) is an increasing concern from human health perspectives. Little information on the genotoxic and cytotoxic potential of NP particles in human cells is available. We aimed to assess the cytotoxic and genotoxic potential of polystyrene nanoplastics (PSNPs) at different concentrations (2000μg/mL, 1000μg/mL, and 500μg/mL) by using chromosomal aberration (CA) and cytokinesis-block micronucleus assays (CBMN) on human peripheral lymphocytes.
