Description:
As part of an effort to characterize airborne emissions from petroleum refineries, an ambient air monitoring study was conducted near the Exxon refinery at Benicia, California, during September 8-22, 1975. Ground-level sampling facilities and an airplane equipped with air pollutant monitoring instruments provided an integrated, three dimensional monitoring network. Measurements included ozone, oxides of nitrogen, methane, carbon monoxide, individual C2-C6 hydrocarbons, halocarbons, condensation. Increased concentrations of hydrocarbons, carbon monoxide, condensation nuclei and nitrogen oxides, as well as decreased ozone levels were observed less than five miles from the refinery. At distances greater than 5 miles, elevated condensation nuclei and hydrocarbons were still observed but no discernible differences from background could be detected in NOx, O3, and CO.
