Poor air quality in Norwegian cities
Air quality is currently poor in both Oslo, Bergen, Trondheim and Stavanger. The cause is pollution from cars and heating combined with low temperatures and stagnant air.

STAVANGER
In Kannik area in centre of Stavanger is so poor air quality that allergy sufferers and people with heart and respiratory illnesses are warned not to stay outdoors.
OSLO
In Oslo the past 24 hours have been recorded very poor air at two measuring points, the Hjortnes in Oslo harbor and Bygdøy Avenue. Air quality in these areas has been a health hazard for vulnerable groups, such as asthmatics and people with cardiovascular disease.
Thursday saw some improvement, but the senior researcher at the Norwegian Institute for Air Research (NILU) Dag Tønnesen, told NTB that there is a worsening back already from Friday.
Worsening
- From Friday it reported lower temperatures down in the city but it will be in North Marka. It will lead to a worsening of air quality in the center of a level which is already bad, "said Tønnesen NTB.
In Oslo, nitrogen dioxide, particulate matter and emissions as a result of increased heating demand that creates the bad air. In Trondheim, the cause is the same. In Bergen, it is mainly nitrogen. In Stavanger is the registration of bad air caused by particulate matter (svevestøv).
- We are somewhat surprised by the scale we have in Stavanger last day. Stavanger is not the same "pot effect" as particularly Bergen and Oslo. It is more open to the fjord. Yet it is as much particulate matter in areas of the city that air quality is poor.
Health risks
In Kannik area in Stavanger is so poor air quality that allergy sufferers and people with heart and respiratory illnesses are warned not to stay outdoors.
TRONDHEIM
In Trondheim it was Thursday moderate health risks. The worst was in the area around Market and the Heimdal Myra.
BERGEN
In Bergen was also the health risk moderate Thursday, but with a notice worsening of the evening and Friday.
In the Grenland area (Skien-Porsgrunn) are also notified significant deterioration of air quality on Friday.
In the other cities in the country are either moderate, little or no health risks due to air quality.
Less driving
Traffic and heating creates a great deal of pollution, which is visible and palpable discomfort in stagnant, cold air.
It is the oldest, worst-maintained cars and the oldest and worst wood-burning stoves that pollute the most. And the cheaper and less qualitative wood is, the more polluting it is, "says Tønnesen.
For example, spruce give greater emissions than the birch and raw wood providing greater emissions than dry wood. Tønnesen also calls for using good moves in the wood-burning oven.
He understands very well that it is less tempting to stand on the platform and wait for the train or the bus when it's really cold, but to pollution away people must drive smaller cars and avoid fire with bad fuel in old furnaces.
