HMTC A chemical element mass balance (CEB) receptor model has been developed to monitor air pollution in Chicago, IL. Analyses are performed to determine the total suspended particulate matter (TSP) and the respirable particulate matter (RP) in the environment. The sources of the particulate matter are steel production, mobile sources, soil-derived aerosol, refuse incineration, cement and limestone, oil combustion, and coal combustion. Included in this study are CEB predictions compared to dispersion model predictions, sensitivity analysis of the model's input matrix, and a statistical analysis of modeled results. The conclusions indicate that the CEB model can be used in a large, urban area to predict TSP, but further studies need to be conducted to improve the RP coefficients of determination. (40 ref.)
