Notes:
Value of mortality reduction = $7.4M per case in 2006$.
Beta = percentage change in mortality for a 1 μg/m3 change in PM2.5 concentration.
(a) = uniform application of the 0.69 scaling factor to account for sources of aromatic emissions.
(b) = rural areas adjusted by 0.69; 100% of aromatic emissions in urban areas assumed to originate from gasoline.
