Mass spectrometry as a powerful analytical tool for the characterization of indoor airborne microplastics and nanoplastics
AI summary Read the abstract
This review covers recent mass spectrometry-based analytical methods for determining the size, chemical identity, and quantity of microplastics and nanoplastics in indoor air and dust. It highlights how advances in single-particle mass spectrometry are enabling more sensitive detection of nano-sized plastic fragments in indoor environments.
In this review we discuss the novel developments in mass spectrometry-based analytical methods for size determination, chemical identification, and quantification of the microplastic and nanoplastic in indoor air and dust.

Size-Resolved Identification and Quantification of Micro/Nanoplastics in Indoor Air Using Pyrolysis Gas Chromatography–Ion Mobility Mass Spectrometry
AI summary Read the abstract
Scientists developed a new method to measure micro and nanoplastics in indoor air down to 56 nanometers in size, using advanced mass spectrometry techniques. They found significant concentrations of plastic particles in both a laboratory and a private home, with polystyrene being the most common type, and also detected flame retardant chemicals associated with plastic furniture foam. This study provides some of the first evidence that people are breathing in substantial amounts of nanoscale plastic particles indoors, where most people spend the majority of their time.
