AIR Indoor air measurements Improved measurement techniques are needed to understand the role of fungal growth in indoor air quality problems. Previous studies identified a strong relationship between home dampness (elevated humidity) and reported respiratory health effects, and the role of high humidity in promoting fungal growth has received the most attention. J. D. Miller and J. C. Young describe a method for measuring ergosterol in indoor air and using it as an indicator of fungal exposure. Air sampling for ergosterol proved to be 3. reliable indicator of the total fuiisslfoiorn
