| Popis: | Two indicator pollutants, carbon monoxide (CO) for mobile source influence and sulfur dioxide (SO2) for stationary source influence, were used to estimate source-type contributions to ambient NO2 levels in a base year and to predict NO2 concentrations in a future year. For a specific source-receptor pair, the so-called influence coefficient of each of three source categories (mobile sources, power plants, and other stationary sources) was determined empirically from concurrent measurements of CO and SO2 concentrations at the receptor site and CO and SO2 emissions from each source category in the source area. Those coefficients, which are considered time invariant, were used in conjunction with the base year and future year NO x emission values to estimate source-type contribution to ambient NO2 levels at seven study sites selected from the Greater Los Angeles area for both the base year period, 1974 through 1976, and the future goal year of 1987 in which the air quality standards for NO2 are to be attaine... |
