This study investigates the leaching of phthalates and non-phthalate plasticizers from commercial PVC and their abiotic and biotic degradation under various conditions (aerobic and anoxic) environments for biotic conditions, utilizing sediment water slurry. The microbial community and functional genes profile were also determined for different conditions. Interestingly, 35-79% of plasticizers were released into the sediment from the microplastics (MPs) within 30 day and >99.9% degradation was achieved. Although a significantly higher degradation was found in plasticizer-added microcosms under biotic processes (overall, 94%), there was a noticeable abiotic loss (72%), suggesting that abiotic processes also play a role in plasticizer degradation. Furthermore, changes in the bacterial community, abundance of plasticizer-degrading bacterial populations, and functional gene profiles were assessed. In all the microcosms, a decrease in bacterial community diversity and a notable shift in bacterial composition were observed.
