NOAA, partners find about 98% decline in VOCs concentrations in LA Basin over last 50 years despite 3x increase in use of gasoline and diesel

Green Car Congress

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.

Pollution plumes in Paris air are richer in gaseous aromatic compounds than in LA; gasoline engines main source of VOCs

Green Car Congress

The study also shows that the proportion of gaseous aromatic compounds—apart from benzene—in hydrocarbon emissions is two to three times greater in pollution plumes in Paris than in Los Angeles, even though the total quantity of hydrocarbons emitted in Los Angeles remains considerably greater than in Paris.

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. The United States and California state averages shown are based on total on- and off-road use. The urban areas in California shown are for on-road fuel use only.
