Benzene from traffic

29-05-2000

Measurements of benzene and other aromatics in air were made at Jagtvej in Copenhagen, 1994-99 and at Albanigade in Odense 1997-99. Levels, trends and emissions of e.g. benzene form the actual car fleet were determined. In addition, analysis of Danish petrol was analysed for aromatics. The investigation showed a clear relationship between benzene content from 3,5 % in 1994 to 1 % in 1998 lead to the expected reduction in air, but the larger fraction of cars with three way catalysts reduced the air concentrations even more.
