Release of Microplastics from Reusable Kitchen Plasticware and Generation of Thermal Potential Toxic Degradation Products in the Oven

Plastics are one of the most important technical materials at present, yet they associated with a whole series environmental problems such as micro-and nanoplastics or their plasticizers, which have become increasingly relevant in recent years. While there many studies that focus on microplastics (MPs) introduced into human body through commercially produced food, nearly none consider MPs we ingest homemade food made plastic kitchen utensils mixing bowls. To investigate this, samples were obtained by exposing different bowls acrylonitrile–butadiene–styrene (ABS), polypropylene (PP), melamine, polyethylene (PE), polystyrene (PS), and styrene–acrylonitrile (SAN), to mechanical stress then analyzed via infrared spectroscopy. This not only raises question whether incorporated foods but also extent degradation products thermal an oven could play toxicological role. Degradation generated pyrolysis afterwards using gas chromatography mass spectrometry. There differences number microplastic particles abraded types plastic, consisting melamine (898 particles) least low-density (331 particles). relevance for plastics, so assessment would be evaluated further work.
