NO2 ambient concentrations in Switzerland
Modelling results for 2005, 2010, 2015
| Year | 2011 | |
|---|---|---|
| Description | Nitrogen dioxide (NO2) concentration levels are modelled for Switzerland, based on updated NOx emission inventories and on a dispersion model. An emission reduction of 27% is expected in the period 2005–2015 due to a number of reduction measures. The concentration levels for 2005–2015 continuously follow the decrease of the emissions. In 2005, the average population weighted NO2 concentration is 23.2 microgram/m3 and drops to 18.9 microgram/m3 until 2015. In 2005, 6%–35% of the inhabitants were exposed to exceeding concentration levels. The number is expected to decrease to 1%–10% until 2015. The exceedances mainly occur in the centres of the cities and along major high-ways. | |
