Indoor Air Pollution and Asthma in Children

(Proceedings of the American Thoracic Society) While there is a large literature linking ambient air pollution and asthma morbidity, less is known about the impact of indoor air pollution on asthma. Concentrating on the indoor environments is particularly important for children, since they can spend as much as 90% of their time indoors. 

Important indoor air pollution determinants of asthma morbidity in urban environments include particulate matter (particularly the coarse fraction), nitrogen dioxide, and airborne mouse allergen exposure. Avoidance of harmful environmental exposures is a key component of national and international guideline recommendations for management of asthma.

This literature suggests that modifying the indoor environment to reduce particulate matter, NO2, and mouse allergen may be an important asthma management strategy.
