Toxicity of polyvinyl chloride microplastics on Brassica rapa.

Environmental Pollution, 2023
Microplastics (MPs) can pose high risk to living organisms due to their very small sizes. This study selected polyvinyl chloride MPs (PVC-MPs) which experienced up to 1000 h UV light radiation to investigate the influence of PVC-MPs on Brassica rapa ...

Effects of biochar on the phytotoxicity of polyvinyl chloride microplastics.

Plant physiology and biochemistry : PPB, 2023
Polyvinyl chloride microplastics (PVC-MPs) are toxic to crops, resulting in economic losses during agricultural production. Owing to its strong adsorption capacity, biochar can effectively remove MPs from water.

Biodegradation of thermo-oxidative pretreated low-density polyethylene (LDPE) and polyvinyl chloride (PVC) microplastics by Achromobacter denitrificans Ebl13.

Marine Pollution Bulletin, 2022
Microplastics pretreatment of prior to biodegradation is an efficient approach for their bioremediation. We isolated Achromobacter denitrificans from compost and used it for biodegradation of thermo-oxidative pretreated polyvinyl chloride (PVC) and low ...

Upcycling waste polyvinyl chloride: One-pot synthesis of valuable carbon materials and pipeline-quality syngas via pyrolysis in a closed reactor.

Journal of Hazardous Materials, 2022
Polyvinyl chloride (PVC) is one of the most commonly used plastics. The treatment and recycling of PVC waste is still challenging, due to its non-biodegradability, low thermal stability, high Cl content and low product value.

The photodegradation processes and mechanisms of polyvinyl chloride and polyethylene terephthalate microplastic in aquatic environments: Important role of clay minerals.

Water Research, 2021
It is well known that microplastics (MPs) may experience weathering and aging under ultraviolet light (UV) irradiation, but it remains unclear if these processes are impacted by natural components, such as clay minerals.

The photo-aging of polyvinyl chloride microplastics under different UV irradiations

Gondwana Research, 2021
Microplastics (MPs) pollution is becoming a global environmental problem due to the ubiquity. Knowledge about transformation process of MPs under ultraviolet (UV) irradiation was critical to understanding the environmental fate of these particles.
