| Abstract |
In this study, a methodology for ambient exposure analysis of carcinogens was developed based on a pilot study of the Detroit Metropolitan area. The specific aim of the analysis was to identify high and low exposure areas within the study area. Four known or suspected carcinogens and groups of carcinogens: BaP, trichloroethylene, nickel and its compounds, and cadmium and its compounds were studied. The analysis of ambient exposure to BaP consisted of the use of the Air Quality Display Model (AQDM) to simulate levels of BaP which might have existed during 1956 to 1960. The analysis for BaP involved a multistep procedure. In order to examine the accuracy of AQDM predicted BaP ambient concentrations, present conditions (1975-1976) were simulated and compared against known concentrations in the area. Next, BaP emissions for the period 1956-1960 were estimated by analyzing past trends for significant sources. This emissions data base, along with meteorological data for the same period, was used as an input to ADQM to predict historical exposure to BaP. The analysis for the other three carcinogens was less detailed than that for BaP. It was comprised of estimation of emissions and calculation of emission density for each of the three carcinogens. For nickel and cadmium, it also included a comparison of spatial variation in emissions with measured air quality patterns in the Detroit area. |
