ABSTRACT

Microplastics have become pervasive in the environment, including dust. These particles pose potential health risks due to their ability to be inhaled and accumulate in humans. This study aims to provide a comprehensive analysis of the molecular composition of partially depolymerized microplastics and additives in indoor dust using non-target analysis (NTA) with liquid chromatography high-resolution mass spectrometry (HRMS). Non-target analysis was conducted with MSMS spectral library matching identification. Then, statistical analysis was used to reveal the differences in the compositions of microplastics in indoor dust collected in various locations.
