Summary

Researchers surveyed settled dust in university buildings in Puerto Colombia, Colombia, and found that laboratories had the highest concentrations of microplastics. The predominant particles were fibers in the 100-500 micrometer range, composed mainly of PET, polypropylene, and polyester. The findings highlight indoor academic environments as a notable but underexplored source of microplastic exposure.

Polymers

PET PP

The indoor university environment in Puerto Colombia, Colombia, with the highest mean MPs was the laboratory. Fibers (501–100 μm) and PET, PP, and polyester microparticles were predominant.
