3 de jun. de 2021 · About 10% of consumer plastics and 2% of environmental plastics were constructed of PVC, with the discrepancy attributed to the long service lives and managed disposal of PVC used in the construction sector and the propensity of the plastic to sink in aquatic systems and evade detection.
22 de oct. de 2023 · In a recent study, PVC samples degraded by 10% and 32% after 1 month of incubation with Aspergillus niger and Aspergillus glaucus, respectively [ 43 ]. Additionally, weight reductions ranging from 15% to 20% were observed for PVC treated with fungal strains over a 2-month period [ 44 ].
