Kawecki, J. EMISSION OF SULFUR-BEARING COMPOUNDS FROM MOTOR VEHICLE AND AIRCRAFT ENGINES. A REPORT TO CONGRESS. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/9-78/028 (NTIS PB295485), 1978.
Description:
This report was generated in response to section 403(g) of The Clean Air Act as amended August, 1977. The report covers (1) a review of emission factors for H2SO4, SO2, sulfate, H2S, and carbonyl sulfide from motor vehicles, motor vehicle engines and aircraft engines; (2) a review of the known effects on health and welfare of these compounds; (3) the status on technology to control such emissions; and (4) an analysis of the costs of control weighed against the social benefits of such control. Available emission factors for these pollutants were converted to ambient air concentrations by using dispersion and stochastic models. The predicted ambient air concentrations were compared to concentrations of these pollutants known to cause adverse health or welfare effects. Results of this comparison suggest that benefits of any control are likely to be small. Except for 3-way catalytic control technology, cost data for fuel desulfurization and vehicle on-board control technology suggest an extremely large economic impact. Consequently, specific controls of sulfur-bearing compounds from mobile sources are not recommended.
