What’s Lurking in Common Dust Found in Homes, Businesses, and Schools in Puerto Rico?

House dust is a part of everyday life, yet few people fully understand what it contains or how it can impact human health. Far from being simple dirt, house dust is a complex mixture of materials originating from both indoor and outdoor environments. These may include soil particles, human skin cells, pet dander, textile fibers, pollen, mold spores, and microscopic organisms such as dust mites and their waste byproducts.

For many individuals, exposure to house dust can trigger allergic reactions. Common symptoms include sneezing, itchy or watery eyes, nasal congestion, and skin irritation. For those living with asthma, dust is a well-known trigger that can lead to coughing, wheezing, chest tightness, and, in some cases, severe asthma attacks.

The level and type of exposure often depend on particle size and human activity. Fine dust particles can become airborne and easily inhaled, while larger particles tend to settle on surfaces where they may come into contact with the skin. Hand-to-mouth contact is another important exposure pathway, particularly for young children, raising the risk of ingesting contaminated dust.

“In certain environments, especially older or poorly maintained buildings, house dust may pose more serious health concerns,” said Harry Peña, President of Zimmetry Environmental. “Deteriorating lead-based paint can introduce harmful lead particles into dust, which is particularly dangerous for children. Similarly, damaged asbestos-containing materials can release microscopic fibers that present long-term respiratory risks if disturbed. In healthcare settings, dust could contain mold spores that could be a serious health concern for any patients with weakened immune systems.”

Zimmetry Environmental helps to ensure that households, institutions, and businesses across Puerto Rico can maintain safe and healthy indoor environments. Their team of industrial hygiene and building science professionals identifies exposure hazards related to a wide range of microbial, chemical, and radiological contaminants. They also collaborate closely with clients to develop effective strategies to eliminate or mitigate any risks found.

As part of its commitment to public education, Zimmetry recently sponsored an informative video about house dust and exposure risks. The video is available at: https://youtu.be/orAieRq6vcc
