First, we used air pollution data collected from a single monitoring site for personal pollution exposure and therefore, some extent misclassification might happen.
As seen typically in studies of air pollution collected from cities, there seems to be large seasonal differences in PM10 and PM2.5 both with regard to chemical composition and their biological effects as measured as proinflammatory cytokine release and cytotoxicity [ 184].
