Elucidating the effects of naturally weathered aged-polypropylene microplastics and newly procured polypropylene microplastics on raw 264.7 macrophages

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.
