A new analysis from the French CRESPI study, published in Environmental Health, finds an association between higher concentrations of volatile organic compounds in daycare facilities and increased wheeze among the children who attend them.
The authors measured indoor VOC levels across a network of French daycares and matched the readings to respiratory symptom reports from children in those settings. Higher cumulative exposure tracked with a higher likelihood of wheeze, an early indicator of asthma and chronic airway inflammation.
Indoor air contaminants such as VOCs frequently co-occur in damp, poorly ventilated, or water-damaged buildings, where they can compound the respiratory burden created by mold growth and bacterial colonization on building materials.
