- Air pollution and lung function among susceptible adult subjects: a panel study

..................................................

Figure 1:Scatter plot of ambient* PM2.5 and indoor** concentrations (μg/m3), by seasonand home*Averages of PM2.5 24 h concentrations (μg/m3) at two sites (Villa Ada and ISS). **PM2.5 24 h indoor concentrations (μg/m3) in each home participating in the side validation study. Spring = 1 and Winter = 2. 1 to 5.
