Today the California Air Resources Board (CARB) released the first ever study of indoor air quality in new homes. The report was alarming.
The researchers found the majority of homes had ventilation rates that did not meet code.
The median 24?hour outdoor air exchange rate was 0.26 air changes per hour; 67 percent of the homes were below the California building code requirement of 0.35 air changes per hour…
Low ventilation rates allow chemicals to concentrate inside homes. Formaldehyde was present at levels that can cause illness.
Nearly all homes had formaldehyde concentrations that exceeded guidelines for cancer and chronic irritation, while 59 percent exceeded guidelines for acute irritation.
The report recommended education regarding the need to reduce formaldehyde exposure. Formaldehyde causes asthma, bronchitis, sinus infections, and headaches. Formaldehyde is also a carcinogen and has been linked to leukemia.
Testing is the only way to know the formaldehyde concentration in a home. Test badges cost as little at $40 each, including laboratory analysis. An industrial hygienist can help identify major sources of formaldehyde in a home.
