air quality
Lead in particulate matter
Lead is a toxic heavy metal and usually occurs bound to other substances. In ambient air lead is measured bound to particulate matter.
Nickel in particulate matter
Nickel belongs to the heavy metals and usually occurs bound to other substances. In ambient air arsenic is measured bound to particulate matter.
Cadmium in particulate matter
Cadmium is toxic and cancerogenic. It belongs to the heavy metals and usually occurs bound to other substances. In ambient air arsenic is measured bound to particulate matter.
Benzo(a)pyrene in particulate matter
Benzo(a)pyrene is a polycyclic aromatic hydrocarbon. It is used as a marker for the carcinogenic risk of polycyclic aromatic hydrocarbons in ambient air.
Arsenic in particulate matter
Arsenic is toxic and can have metallic or non-metallic characteristics. It rarely occurs elementary but most of the time bound to other substances. In ambient air arsenic is measured bound to particulate matter.
Air quality maps: Background information
How are the German Environment Agency's maps of Germany's current air pollution and ozone concentration forecasts drawn up? We explain here in brief.
Quick guide on how to use "Current air data" information pages
Experts at the monitoring stations of the German states and the German Environment Agency take multiple daily measurements to determine the air quality in Germany. Shortly after measurements are taken, you can go to our “Current air data” webpage to look up measured values, some forecast data, and data on past years.
