In California’s Los Angeles Basin, levels of volatile organic compounds (VOCs) pollutants have decreased by about 98% since the 1960s, even as area residents now burn approximately three times as much gasoline and diesel fuel. CO2 ratio for this flight track segment decreased from 24.5 ppbv/ppmv to 10.7 Source: Warneke et al.

Contribution of gasoline and diesel exhaust to SOA over 0% to 50% diesel fuel use. SOA contributions from the two sources are equivalent at 6% diesel fuel use. These compounds in un-burned gasoline and diesel fuel dominate vehicular emissions of reactive gas-phase carbon that have the potential to form SOA.
