Smog chamber studies on photochemical aerosol-precursor relationships. Final Report, Jun 1974--Aug 1975

Technical Report ·
OSTI ID:7226401
An experimental program was conducted in which controlled atmospheres containing water vapor, CO, NO/sup x/ (NO + NO/sup 2/), and a constant distribution of 17 hydrocarbons (NMHC) were irradiated in a smog chamber. Reaction profiles were developed for NO oxidation, hydrocarbon oxidation, ozone formation, and aerosol formation over 10-hour irradiation periods. Comparison of smog chamber results with data on hydrocarbon oxidation rates observed in the Los Angeles area and with worst-case ozone episodes in that area, suggest that the models (precursor relationships) developed (in this study) for photochemical aerosol formation are highly relevant to smog problems in polluted atmospheres.
