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. —lead author Carsten Warneke, Ph.D., Warneke, C., de Gouw, J. Holloway, J. Peischl, T. Ryerson, E.

Berkeley study identifies diesel as main source of vehicular secondary organic aerosols

Green Car Congress

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.

Study uncovers role of longer-chain unburned hydrocarbon emissions from diesels in London air pollution; calls for regulatory shift

Green Car Congress

The study found that 60% of the winter primary hydrocarbon hydroxyl radical reactivity in London is from those diesel-related hydrocarbons; the authors predicted that the longer-chain HCs contribute up to 50 % of the ozone production potential in London. —Dunmore et al. Dunmore et al.
