Hi! The English site is only a beta for now and still has many errors (especially in names and locations).
We are working hard to fix them and making more content available than ever before so expect constant updates.
Air quality in Reykjavik is generally good, but nitrogen dioxide (NO2) and fraud (PM10) are the substances most likely to exceed health protection levels. Other atmospheric pollutants measured in the city include sulphur (H2S), carbon monoxide (CO), sulphur dioxide (SO2) and benzene (C6H6), but are generally well below the limit values in Reykjavik.
The objective of air quality regulation is to prevent or reduce the harmful effects of air pollution on human health and the environment, assess air quality in a consistent manner, obtain information on air quality and maintain it where it is high, or improve it. At the same time, it is a goal to reduce air pollution.
Regulation 787/1999 The limit values
for air quality are maximum permissible levels of pollution and are classified into several types according to the circumstances to which they apply. The main limit values are health protection limits, but crop protection limits are also laid down in regulations for certain substances.
Table 1 below shows the health protection limits for atmospheric pollutants according to the following regulations:
Regulation 920/2016 on sulphur dioxide, nitrogen dioxide and oxides of nitrogen, benzene, carbon monoxide, fraud and lead in the atmosphere, the concentration of ozone at the Earth's surface and on public information. Regulation 514/2010 on the concentration of sulphur in ambient air.
