Abstract
A sulfuric acid review conference sponsored by EPA's automotive Catalyst Research Program was held recently at Hendersonville, NC, for researchers whose work is funded by EPA. Emissions characterization research indicated that in-use catalyst-equipped vehicles emit low levels of H2SO4, averaging 2.7 mg/mile for 49-state cars and 15 mg/mile for California cars. Research on measurement methodology for H2SO4 and other sulfate compounds has led to the development of several promising techniques based on selective volatilization. In-roadway and off-roadway monitoring programs are providing sulfate data which can lead to improved mathematical predictive models. Acute toxicity studies to date indicate that morphological, biochemical, physiological, and pharmacological alterations due to inhaled H2SO4 alone do not appear to occur at levels less than 1 mg/cu m. However, striking effects are noted with combinations of H2SO4 and other pollutants. Participants identified the need for long term chronic H2SO4 exposure studies.
