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. read more


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. read more


Heavy Metals in Particulate Matter (PM10)

Heavy metals in ambient air rarely occur elementary but most of the time bound to particulate matter. By inhalation health risks arise because some pollutants like arsenic, cadmium and nickel are classified to be cancerogenic.The European directive 2004/107/EC regulates the measurement and assessment of arsenic, cadmium and nickel in particulate matter (PM10). Lead in particulate matter... read more


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. read more


Indicator: Air quality in agglomerations

A graph shows how strongly, on average, urban background levels of three main air pollutants in German agglomerations exceeded World Health Organisation (WHO) recommendations between 2000 and 2020. The trend for the different pollutants varies. Between 2000 and 2020, the values for nitrogen dioxide were between 35.9 and -19.8 percent, for ozone between 71.0 and 57.3 percent and for particulate matter (PM2.5) between 77.3 and -1.0 percent.

The background level of one main air pollutant (ozone) in German agglomerations still exceeds World Health Organisation (WHO) guide line values.Close to sources, pollutant levels can even be significantly higher.The situation regarding nitrogen dioxide and particulate matter has greatly improved since 2000. In 2020, the mean value fell below the WHO recommendation for PM 2.5 for the first time.Ozo... read more

Indicator: Population exposure to particulate matter pollution

A diagram shows in chronological order from 2010 to 2018 the number of people in Germany affected by exceeding the World Health Organization (WHO) guideline value for particulate matter (PM2.5). The exposure decreased significantly between 2010 and 2018. However, it should be noted that measuring stations located in conurbations with high traffic volumes were not included in the calculation.

The exposure of the population to particulate matter (excluding traffic-related measuring points) was significantly lower in 2018 than in 2010.Particulate matter concentrations in ambient air are considerably affected by weather conditions which may vary substantially within the year and from one year to another.The German Environment Agency (UBA) proposes a target of keeping the exposure of the e... read more
