Funded Activity Summary

Research has shown that exposures to air pollutants such as nitrogen dioxide (NO2), sulphur dioxide, ozone and respirable particulate matter less than 10 microns are associated with respiratory symptoms. Unlike the other air pollutants nitrogen dioxide is an indoor gas which occurs in higher concentrations than outdoors in households which cook or heat with gas. Recent research has demonstrated that NO2 at concentrations easily achieved indoors can increase respiratory illness, particularly in children and asthmatics. In South Australia we have the opportunity to demonstrate health effects of NO2 on children with asthma more conclusively, as a high number of schools heat their classrooms with unflued gas heaters which produce high NO2. In the proposed study, half of the primary schools with unflued gas heaters will have these heaters replaced with heaters which do not emit NO2. This process of selecting schools will be performed at random and in the school holidays, so as not to bias the children in regard to their exposure status. Additionally, only asthmatic children without gas appliances at home will be included. Asthma symptoms and lung function measurements will be collected in order to determine any differences in the health outcomes of both groups. The results of this study will be able to give conclusive information on health effects related to NO2, that will substantially contribute to the development of a recommended NO2 guideline. This is of worldwide interest.
