The aging behavior of polyvinyl chloride microplastics promoted by UV-activated persulfate process.

Journal of Hazardous Materials, 2021
Microplastics (MPs) experienced different aging processes in environment. Literatures about effect of artificially-accelerated aging on MPs behavior are still insufficient. The accelerated process induced by ultraviolet(UV)-activated persulfate (PS) is a

Molecular interactions of polyvinyl chloride microplastics and beta-blockers (Diltiazem and Bisoprolol) and their effects on marine meiofauna: Combined in vivo and modeling study.

Journal of Hazardous Materials, 2022
The ecotoxicological effects of beta-blockers (i.e. Diltiazem and Bisoprolol) and their interactions with the microplastic polyvinyl chloride on marine meiofauna were tested in laboratory microcosms.

Production, Use, and Fate of Phthalic Acid Esters for Polyvinyl Chloride Products in China.

Environmental Science and Technology, 2021
Phthalic acid esters (PAEs) are the most common plasticizers, approximately 90% of which are used in polyvinyl chloride (PVC) products, but they are also endocrine disruptors that have attracted considerable attention.

Bioremediation of polyvinyl chloride (PVC) films by marine bacteria.

Marine Pollution Bulletin, 2021
Polyvinyl chloride (PVC) is the third one after polyethylene and polypropylene in the production demand. It intends to grow further, causing an increase in the risk of health and ecological problems due to environmental accumulation and incineration.
