Researchers suggest that air quality tests need simplifying to help reduce dangerous emissions

Green Car Congress

New methods of testing and simulating air quality should be considered in order to help policy makers have a more accurate understanding of how emissions affect air pollution levels, new research suggests. The researchers compared current techniques used to describe atmospheric chemical reactions against more historical techniques.
