Ozone & nitrogen cycle

The chemistry around us

Ozon und Stickstoffkreislauf

Collage: Elmar Uherek


No. 8

April 2006




Long distance transport of nitrogen and background ozone

Traffic on our streets causes always again ozone smog periods on sunny summer days. Catalytic converters and other measures have reduced the nitrogen oxide burden. However, background ozone is still increasing. We explain why. [more ..]


The nitrogen cycle

As in ozone formation, nitrogen plays an important role in many areas of our environment. The nitrogen cycle describes how nitrogen compounds are converted into each other. [more ..]

WebQuest on the nitrogen cycle

In parallel to classes on nitrogen compounds, oxidation states and technical processes the students explore in self-contained work numerous relations to environment and climate. The WebQuest is a successfully tested approach. [more ..]

Links about the nitrogen cycle

Here you find more websites and explanations while studying the nitrogen cycle. [more ..]

Information for teachers

Here you find links to downloadable materials and recommendations for the integration of this magazine into the curriculum, in particular for the nitrogen cycle in chemistry classes. [more ..]
