  9. 9. BY THE WAY, THIS IS NOT A SURPRISE…. QUARG report 1993 Diesel vehicle emissions and urban air quality ‘In the view of the Review Group, the impact of diesel vehicles on urban air quality is a serious one. Any increase in the proportion of diesel vehicles on our streets is to be viewed with considerable concern unless problems of particulate matter and nitrogen oxides are addressed .’
