What is the Populations Estimated Total Air Exposure Concentration of Diesel Exhaust Particulate Matter in California?
The CPIEM was also used by ARB staff to estimate the population’s total air exposure to diesel exhaust particles by combining indoor and outdoor air exposure estimates. The model uses the distributions of indoor concentrations, outdoor concentrations, and data on Californians’ activity patterns to develop time-weighted population exposure estimates. The population time-weighted average total diesel exhaust particulate air exposure concentration across all environments (including outdoors) is estimated to be 2.1 (+ 0.8) g/m3 in 1990. We have also estimated total air exposure for 1995 using the same method as used above to calculate the 1995 average indoor exposure concentration estimate. The ratio of the 1990 average total air exposure concentration and the 1990 outdoor population-weighted average estimate is 2.1/3.0. Thus, the 1995 estimated average total air exposure concentration is 2.1/3.0 of 2.2 g/m3 (1995 population-weighted outdoor estimate), or approximately 1.5 g/m3. These tota
