Occupational Exposure to Elevated Levels of Inhalable Microplastics in Plastic and Fiber Factory Workers
AI summary Read the abstract
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.
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

Microplastics as an emerging source of particulate air pollution: A critical review
AI summary Read the abstract
This review examines airborne microplastics as a form of particulate air pollution, highlighting risks especially for factory workers who handle plastics. Microplastics have been detected in both indoor and outdoor air, where they can be inhaled deep into the lungs. The authors note significant gaps in understanding how airborne microplastics affect air quality and human respiratory health, and call for better monitoring and occupational safety standards.
