Why Test for Eye Irritation Sources?
Eye irritation in residential spaces is often caused by airborne contaminants such as formaldehyde or mould spores. While these substances are common, they are not always obvious. Testing allows you to pinpoint the source of irritation, guiding effective remediation efforts to safeguard your health and comfort.
Formaldehyde: A Hidden Hazard in Your Home
Formaldehyde is a toxic and carcinogenic gas regulated in Ontario, with residential limits set at 40 parts per billion (ppb) (Health Canada, 2015). At these low concentrations, formaldehyde’s odour may be undetectable, yet it can cause significant dryness and irritation of the eyes. Prolonged exposure is linked to asthma and lung diseases.
Common sources of formaldehyde include:
- New furniture and flooring (laminate or hardwood)
- Urea formaldehyde foam insulation (new or aged)
- Smoke from fireplaces, candles, and cigarettes
- Woodworking and electronic soldering hobbies
Seasonal risks: Formaldehyde-related irritation often worsens during winter and summer when windows remain closed, allowing concentrations to accumulate indoors.
Mould: A Widespread Allergen
Mould spores, ranging from 1–15 microns in size, are a frequent cause of eye irritation and allergies. Mould thrives in damp conditions, particularly when humidity levels exceed 50%.
Common situations where mould thrives:
- Previous history of allergies in the household
- Water damage, including hidden leaks behind walls or under carpets
- Sustained indoor humidity levels above 55%
