The level of sulphur dioxide in cities has declined in many countries, and in Sweden it hardly constitutes a health problem any more.
The level of nitrogen dioxide, on the contrary, has not declined.
The guideline value for nitrogen dioxide is exceeded in areas with high traffic density, and may be close to the level where asthmatics could be affected.
The guideline value for carbon monoxide can also be exceeded in such places and give symptoms in persons with heart and lung diseases.
Levels of ozone are enhanced in the southern part of Sweden during summertime and are periodically in the range where irritation symptoms can be expected.
Generally, there is an increased lung cancer incidence in cities compared to rural areas.
