Studies have shown an association between ambient fine particulate matter (PM2.5) and health impacts, particularly for children and the elderly. As part of a larger study, PM2.5 concentrations were measured using the DustTrak (Model 8520, TSI, St. Paul, MN, USA) at two elementary schools (Site A and B) within the city of London, Ontario (Canada). Site A was located in a suburban environment while site B was in an urban setting. Monitoring took place for three weeks during winter (Feb. 16 - Mar. 8) and three weeks during spring (May 05 - 25) of 2010. The winter campaign monitored indoor PM2.5 and outdoor NO2 only, while the spring campaign added additional monitors (outdoor PM2.5 and indoor CO2) after the first week. Site B's indoor PM2.5 concentrations were greater compared to Site A. Outdoor PM2.5 concentrations were similar at both sites. Good correlations were observed between indoor and outdoor PM2.5 concentrations at both locations.
