Nanoplastics from ground polyethylene terephthalate food containers: Genotoxicity in human lung epithelial A549 cells.

The ubiquitous pollution of plastic particles in most environmental matrices leads to concern about any potential adverse effects on human health. Most studies on the toxicological effect of nanoplastics has focused on standard particles of polystyrene. In reality humans are exposed to a large variety of different types and sizes of plastic material via oral intake and inhalation.
