Investigating the microwave degradation of polypropylene microplastics and their impact on human intestinal cell models.

In Tukey’s HSD comparisons against PP_Pristine, PP_Cycle10 produced a highly significant metabolic decrease (p < 0.001), and PP_30 min continuous yielded a highly significant metabolic increase (p < 0.001).

Although this increase did not reach statistical significance at either 24 or 48 h, the data suggests that PP exposure – Pristine and MW degraded - might cause minor perturbations to cell membrane.
