Abstract:Exposure levels of PM2.5, CO of a panel including 33 cardiovascular elderly subjects in summer in one community of Beijing was studied. Concurrent fixed site, outdoor and indoor pollution were monitored, and time-activity data were collected from each subject. Twenty-four hour averaged exposure concentrations of PM2.5, CO for the elderly were 89.6μg/m3 and 1.9×10-6, respectively. The outdoor and indoor concentrations of PM2.5 showed temporal variation, and were affected by meteorological conditions, as well as indoor and outdoor emission sources. The correlations of indoor, outdoor and fixed site concentrations showed that outdoor and fixed site CO was more affected by local sources, while PM2.5 was not. PM2.5 might be the main pollutant contributing to the adverse health effects on cardiovascular elderly in Beijing.
