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.

Other research has shown that carbonyls directly influence physiological response to diesel exhaust particles and can also contribute to secondary organic aerosol formation. In the Tianjin study, they team fueled a four-cylinder light-duty diesel engine fueled with CFT and DF, identifying 13 individual carbonyl compounds in the exhaust.

They found that levels of pollutants that can contribute to the formation of ground-level ozone, or smog, have failed to continue a fairly steady decline as estimated by the US Environmental Protection Agency. These results show that meeting future air quality standards for ozone pollution will be more challenging than previously thought.

Traffic contributes more to NO x emissions in Europe than previously thought, according to a new study by a team at the University of Innsbruck. The majority of the emissions is caused by diesel cars. An open-access paper on their work appears in Scientific Reports. TWC treatment can lead to a 10 fold reduction of NO.

Researchers at Tohoku University in Japan have identified a way to reduce harmful NO emissions produced by ammonia fuel during combustion. Nitric oxide is known to be harmful to human health, contributes to ozone depletion, and when it reacts with other compounds, contributes to acid rain and atmospheric warming.
