Abstract
The presence of particulate PAH and mutagens and other air pollutants (soot, particles, CO, NMHC, NO, gas NO{sub y}, particulate metals, sulphate, chloride and bromide) was investigated in a busy street (60,000 vehicles each day) in Central Copenhagen and in a park area adjacent to the street in the period January - March. The concentrations of benzo(a)pyrene and benzo(e)pyrene (BeP) were 4.4 {+-} 1.2 and 4.4 {+-} 0.7 ng/m{sup 3}, respectively, in the busy street and 1.4 {+-} 0.6 and 1.3 {+-} 0.3 ng/m{sup 3}, respectively, in the park area. Applying BeP as PAH indicator the traffic contribution was estimated to be 80% in the street. The weekdays distribution was as follows: Working days: 90%. Weekends: 60%. In the city park area the working days traffic contribution was estimated to be 40%. The simple chemical mass balance method performed to do these estimates applying the ratio between benzo(ghi)perylene and BeP and that between coronene and BeP was demonstrated as a control to give a satisfactor description of the PAH contribution from traffic sources and from other sources in different cases: A city traffic PAH profile was determined. The busy street PAH profile was very close to the city traffic one.

The busy street PAH profile was very close to the city traffic one. The diurnal variation of PAH showed peaks in the morning and afternoon rush hours and the lowest concentrations in the night hours and was very close to the diurnal variation of the traffic gases, CO, NO and gas NO{sub y}. A method to differentiate between PAH contribution from petrol vehicles and those from diesel vehicles was developed and applied. It is concluded the PAH contributions from petrol vehicles and from diesel vehicles are comparable. (au) (13 tabs., 20 ills., 74 refs.)}
