Abstract |
Based on data collected in St. Louis, Philadelphia and other cities, this evaluation concludes that about 50-80% of the PM-10 concentrations is 'background.' The bulk of the background appears to be of regional origin. The chemical makeup of the background is sulfate as SO4, 21-34%; crustal material, 14-36%; 'unknown' (carbonaceous matter, ammonium, nitrate and water), 36-51%. Dispersion or receptor modeling using a local source inventory or elemental signatures can account only for the incremental contributions from local sources to the total PM-10 mass. It is argued that emission roll-back of local sources will have a limited effect on reducing total concentrations of PM-10. |
