Determination of mass concentrations of airborne PET microplastics using liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS)
Summary
Using liquid chromatography-tandem mass spectrometry, this study measured airborne polyethylene terephthalate (PET) microplastics in the inhalable fraction of ambient particulate matter. The ability to quantify specific polymer types in breathable air is a methodological advance that will help researchers assess how much plastic people inhale daily and what health risks that poses to the respiratory system.
Ubiquitous airborne microplasctics are present in the inhalable fraction of ambient particulate matter. They may induce lesions in the respiratory system dependent on individual susceptibility and particle properties.
