These data show that in the general urban atmosphere of cities in Europe, the median

guideline, is exceeded most frequently, with the highest value 95 Tg/m;. 98-

percentile and 24 hour and 1 hour guidelines are exceeded less often

However, hot spots, i.e. street sites, are not well represented in the data base.

Therefore, these data do not give a representative picture of the extent of exceedances

of short-term (1 hour) average concentrations in Europe.

Traffic is the main contributor in Western European cities and space/domestic heating

in small boiler units the dominating source for NO2 in the former Soviet Union. The

17

emissions in Northern European cities seem to be lower than in Western and Eastern

Europe. The Southern and Central European cities seem to have slightly higher annual

average concentrations. However, these differences have not been shown to be

statistically significant.
