Secondary NOx compounds, and other oxidants formed by oxidation of NO, may also

have a considerable environmental impact, which has to be considered in NOx

abatement strategies. In many European ecosystems, effects of nitrogen deposition and

photochemical oxidants are of greater importance than the effects of high

concentrations of NO2.

Deposition of nitrogen compounds contributes to acidification and eutrophication of

sensitive ecosystems. The deposition of nitrogen over Europe calculated by the EMEP

model (Barrett and Berge, 1996 ) show a maximum deposition near the major source

areas. Deposition of nitrogen oxides is from the ecosystem effect point of view added

to the deposition of reduced nitrogen.
