Summary

Everyday plastic products, including water bottles, disposable cups and packaging, can break down over time into tiny fragments known as nanoplastics. These particles are invisible to the naked eye and can become airborne, raising concerns about their potential to reach deep into the lungs when inhaled. However, most research on the health effects of nanoplastics has focused on polystyrene (PS), partly because particles made from this material are readily available for laboratory studies.
