Dust can contain a wide variety of particles from indoor and outdoor sources, including building materials, combustion byproducts, pollen, mold spores, fibers, skin cells, and other debris. Characterizing these particles can provide valuable insight into indoor environmental quality, potential exposure concerns, and the history of a building's environment.

Eurofins Built Environment Testing offers dust characterization services to support industrial hygienists, environmental consultants, and indoor air quality professionals investigating building-related concerns. Using polarized light microscopy (PLM) and advanced analytical techniques when needed, our experienced analysts identify and characterize dust constituents to help determine potential contamination sources and support informed decision-making.

Dust characterization can complement traditional air sampling by providing a longer-term picture of environmental conditions, making it a valuable tool for indoor air quality assessments, contamination investigations, and post-event evaluations.
