Summary

Researchers compared the effects of naturally weathered polypropylene microplastics and newly manufactured ones on immune cells called macrophages. They found that both types caused cell toxicity and disrupted normal cellular function, but the weathered particles had distinct effects due to their altered surface chemistry. The study suggests that aging and environmental weathering change how microplastics interact with biological systems.

In this work, we investigated weathered aged-PPMPs and naturally obtained polypropylene microplastics (NP-PPMPs) with raw 264.7 macrophages, which causes cytotoxicity and an imbalance in the intracellular system.
