Table 3
Population-weighted concentrations of PM2.5 (mg m"3
) and ozone (ppb) attributable
to combustion emissions from the six sectors considered in this study. PM2.5
population-weighted annual mean concentration is speciated into six categories:
sulfate (Sulf), nitrate (Nit), ammonium (Amm), black carbon (BC), organics (Org) and
unspeciated (Uns). The total concentration of PM2.5 is displayed in the second last
column of the table. The PM concentrations are annually averaged while the ozone
concentration is evaluated as daily maximum averaged over the ozone season (Apre
Sept).
