Abstract

Annual concentration fields of SO2 and NOx for the period 1974–1998 are calculated for a 22 × 18 km2-grid in Oslo. In a study of lung cancer and air pollution in Oslo, 16 209 men living in Oslo have been followed from 1972/73 to 1998. This paper presents a method for estimating their annual residential air pollution exposure for SO2 and NOx. In the exposure assessment the National Population Register provided information on home addresses. Each participant was given an annual average air pollutant concentration outdoors of the address he lived the largest part of that year. Persons living close to streets with high traffic were given an additional concentration, and persons who moved outside Oslo were given a region value for each year. Due to regulations of the sulfur content in fuel oil and a general change of local heating systems to electricity or distant heating, the SO2-concentrations in Central Oslo were reduced during the period from about 60 μg m−3 in 1974–75 to about 4 μg m−3 in 1997–98. Due to the increasing traffic the NOx-concentrations have increased slowly, from about 40 μg m−3 in 1974–84 to about 60 μg m−3 in 1989. After the introduction of catalyst cars the concentrations were reduced to about 45 μg m−3 in 1997–98.
