How clean is air in Germany?
Nitrogen dioxide levels exceeded set limits
A first assessment of the air quality in 2010 done by the Federal Environment Agency (UBA) indicates that at 56 percent of the measuring stations in urban areas near traffic, the nitrogen dioxide (NO2) concentration levels exceeded the annual mean value of 40 microgammes/cubic metre of air (µg/m3) which has been set as the statutory cap since 1.1.2010. The assessment is based on preliminary data from the federal states’ and UBA’s measuring networks. “There is a need for action in the area of nitrogen dioxide. Exceedence of nitrogen dioxide threshold values occurs mainly in cities and congested urban areas; that is, where most people also live,” said UBA President Jochen Flasbarth. The main sources of nitrous oxides are the transport sector and the incineration processes of industry and households. Compared to the past decade, nitrogen dioxide pollution remained similarly high in 2010.
