The Federal Environment Agency (Umweltbundesamt, UBA) has recently launched an online map service aiming to describe the regional distribution of air pollution in Germany since 2001.

At the Geographic Information System (GIS) the visitors are free to enhance the data on air with other geographical information about cities, rivers, and metropolitan areas, and focus on certain characteristics, such as peak loads. Answers regarding the annual average of atmospheric particulates (PM10), nitrogen dioxide (NO2), and ozone pollution in Germany are available free of charge.

At the same time, UBA has published facts and figures on air quality in Germany since 1995 in an information sheet titled Entwicklung der Luftqualität in Deutschland (Development of air quality in Germany). Human stress loads of air pollutants have fortunately been on the decline since the early 1990s. Since early 2000, however, there has been no clear downward trend as air quality has tended to fluctuate from year to year. Despite the successes of clean air policy, the limit values for PM10, which have been valid since 2005, and the caps on NO2, which will apply as of 2010, are already being exceeded in many locations throughout Germany.

The median immissions loads for PM10 and NO2 are highest in metropolitan areas, particularly in the vicinity of emission sources such as high-traffic roads. Pollution loads decrease further out in the countryside but does not apply for ozone. Peak loads are often found outside metropolitan areas at some distance from the sources of its precursors nitrogen dioxide and volatile hydrocarbons.

i would like to suggest as a reference the eParticipation u@marenostrum project as an example

Thanks to interactive maps  users are able to view a
map, perform zoom and pan operations, register their views about
particular issues by placing flags with written comments to appropriate
locations on the map, view the other users' comments and reply to them.
