Non-target screening - a powerful tool for selecting environmental pollutants. NILU OR
The main goal with this project was to test the potential and practicalness of the available non-target screening methods for identification of unknown or new emerging environmental pollutants. It was also desired to try to estimate the quantity of the identified compounds.

NO2 emission from the vehicle fleet in major Norwegian cities. Challenges and possibilities towards 2025. TØI rapport, 1168/2011
2011
The Air Quality in Oslo in 2025 will be worse than previously expected. If the present trend of a high percentage of sold diesel passenger cars will continue it will make the NO2 levels from light vehicles higher in 2025 compared with 2010.This is due to higher emissions of diesel cars in real driving cycles compared to the emissions standards. The calculation of NO2 concentrations in 2025 shows levels that will violate the directives¿ limit values in a large area of Oslo.
Calculations are done for 2010 and 2025 and results from totally 9 dispersion calculations are shown. Firstly 4 reference calculations are considered looking at the effect of the difference of real emissions factors taken from measurement under typically urban driving-cycle compared with the emission standards. There have also been done 3 mitigation calculations with incentives for lower diesel cars sales numbers and two short-time measures limiting the use of cars.
None of these measures are sufficient for keeping the limit values in Oslo and Bærum in 2025 and hence more measures are needed.
