Air pollution and meteorological data from April 17, 2010 to May 10, 2013.
Table 3.
Pearson correlation coefficients among concentrations of PM components.
Fig 1.
The relative risks (RRs) of cardiovascular (A) and respiratory (B) diseases on lag 0 day per one-interquartile range increase in PM2.5 and its components. * PM10, PM2.5, and ammonium were associated with increased risks of cardiovascular disease. CI: confidence interval, OC: organic carbon, EC: elemental carbon. Lag 0 day indicates that the RRs were measured on the day of exposure.
Fig 2.
The relative risks (RRs) of cardiovascular disease per one-interquartile range increase in elemental carbon (EC) (A) or organic carbon (OC) (B) for each age group and sex on lag 0 day. CI: confidence interval.
Fig 3.
The relative risks (RRs) of cardiovascular and respiratory diseases per one-interquartile range increase in particulate matter and the components on lag 0–3 days.
