Polyethylene terephthalate is a common plastic in many products such as viscose rayon for clothing, and packaging material in the food and beverage industries. Polyethylene terephthalate has beneficial properties such as light weight, high tensile strength, transparency and gas barrier. Nonetheless, there is actually increasing concern about plastic pollution and toxicity. Here we review the properties, occurrence, toxicity, remediation and analysis of polyethylene terephthalate as macroplastic, mesoplastic, microplastic and nanoplastic. Polyethylene terephthalate occurs in groundwater, drinking water, soils and sediments. Plastic uptake by humans induces diseases such as reducing migration and proliferation of human mesenchymal stem cells of bone marrow and endothelial progenitor cells. Polyethylene terephthalate can be degraded by physical, chemical and biological methods.

Occurrence, analysis, and toxicity of polyethylene terephthalate microplastics: a review

AI summary Read the abstract

This review focuses on polyethylene terephthalate (PET), one of the most common types of plastic found as microplastic contamination in food, beverages, dust, wildlife, and human tissues. The authors found major inconsistencies in how researchers measure and detect PET microplastics, making it difficult to accurately assess health risks. Better standardized methods are needed to understand the true scope of PET contamination.
