Abatement of Air Pollution in Oslo
Some air pollution components in Oslo exceed the air quality guidelines proposed by the Norwegian State Pollution Control Authority (SFT, 1982). The situation is particularly adverse during the winter time on cold days with inversion and little wind. The incidence of lung diseases is considerably higher in Oslo than in other parts of Norway. The lung cancer incidence is 1.8 times higher in Oslo than in the rest of Norway (Aune, 1982), and air pollution is probably contributing to this together with variations in occupational exposure, smoking habits, diet, and other life style factors. The air pollution may also cause other health effects (Aune, 1982), and a survey has shown that about half of the population in Oslo feel afflicted by dust and unpleasant odours (Norsk Opinionsinstitutt, 1986). Prognoses for the situation towards the year 2000 show an aggravation with respect to some pollution components caused by an expected increase in road traffic and energy consumption, if no further actions are taken to reduce emissions. The already approved decision to require catalytic purification of exhaust in all new cars from 1989, however, will help to improve the situation for nitrogen oxides (NOx), carbon monoxide (CO) and hydrocarbons.
