Summary

Researchers measured inhalable microplastic exposure levels among workers in plastic and fiber factories, finding elevated concentrations of particles small enough to penetrate biological membranes and accumulate in tissues. The fraction of microplastics below 20 micrometers is of particular concern because these particles can induce inflammation and cellular damage. The study highlights that occupational settings in the plastics industry may represent a significant route of human microplastic exposure through inhalation.

Body Systems

Micro(nano)plastics enter the human body mainly through inhalable and oral uptake, and the fraction below 20 μm can penetrate biological membranes, accumulate in tissues, and induce cytotoxicity and inflammation. While inhaled indoor air may be a primary source of exposure, concentrations are potentially higher in occupational settings in the plastic and fiber factories. Here, external exposure to inhalable microplastics
