Abstract

The observed concentrations of the monoaromatic hydrocarbons and aldehydes show significant correlations within the various monoaromatic hydrocarbons, and within the various aldehydes as well as between the two groups of compounds. Moderate or good correlations between observed concentrations of target analytes, monoaromatic hydrocarbons and aldehydes, and other pollutants, CO, NO, NO{dollar}\sb2{dollar} were also found. These observations are consistent with vehicle emission as a major source of monoaromatic hydrocarbons and a primary source of aldehydes in ambient air; CO normalized concentrations were used to infer the occurrence of photochemical reactions in atmosphere. There are significant negative correlations between CO normalized concentrations of monoaromatic hydrocarbons and aldehydes, between monoaromatic hydrocarbons and ozone, and significant positive correlation between CO normalized concentration of aldehydes and ozone. These observations are consistent with the results predicted from the reaction of OH radical with monoaromatic hydrocarbons.
