Abstract

An estimate of the Swedish population`s exposure to urban NO{sub 2} levels has been carried out. The NO{sub 2} concentrations for different municipal districts in 18 Swedish towns/cities were calculated based on modelled results from collected emission inventories. In addition, the contribution of the most significant traffic emissions close to major roads in Gothenburg were modelled and evaluated. The populations subjected to excessive NO{sub 2} concentrations relative to the present national guideline (110 {mu}g/m{sup 3}) and three other cases for short-term exposure (98 per centile of 1 hour averages) were determined using day-time population statistics. The results indicated that ca 26% and 13% of the residents of Gothenburg and Stockholm respectively, are exposed to NO{sub 2} levels exceeding the present national guideline. In the smaller towns virtually no excessive exposure was noted except in the cases of reducing the present limit of 110 {mu}g/m{sup 3}. A rough estimate for the total population of Sweden suggests that ca 3% of the population are subject to ambient NO{sub 2} concentrations greater than the present national guideline for short-term exposure. Due to the limitations of this study and uncertainties coupled with much of the input data, several assumptions and consequently error sources have  More>>

The calculated results are however in line with other international estimates of excessive short-term exposure e.g. UNEP/GEMS. (12 refs., 5 figs., 5 tabs.).}
