Polyvinyl chloride microplastics disseminate antibiotic resistance ...
Polyvinyl chloride (PVC), a common plastic pollutant, is a prominent MP in soil [6]. As the third most common petroleum-based plastic, PVC manufacturing reached 5 million tons in 2018 [7]. When incinerated, particularly at around 200 °C, PVC emits various harmful chemicals, including polycyclic aromatic hydrocarbons and dioxins [8].
Size-selective attachment of polyvinyl chloride microplastics on …
2024年5月15日 · In this work, strong and multi-layered attachment of a mix of heterogeneously size of polyvinyl chloride (PVC) MPs was observed on all the four types of iron oxides, following an order of Fe 3 O 4-i > Fe 3 O 4-s > γ-Fe 2 O 3 > Fe 3 O 4-n. Electrostatic attraction dominated their strong attachment, while hydrogen bonding and halogen bonding ...
