Summary

This systematic review is the first to examine microplastic levels in both indoor and outdoor air and estimate how much people inhale. The findings suggest we are breathing in microplastic particles daily, with indoor air often containing higher concentrations due to synthetic textiles and household materials.

Study Type Review

This study is the first known systematic review of inhalational MP exposure from indoor and outdoor air. It also provides inhalational exposures calculated from previously published environmental samples of MPs as well as from toxicology studies.
