Umwelt-Indikator

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 2018. The trend for the different pollutants varies. Between 2000 and 2018, the values for nitrogen dioxide were between 35.9 and 1.9 percent, for ozone between 71.0 and 76.8 percent and for particulate matter (PM2.5) between 77.3 and 24.8 percent.

The background levels of three main air pollutants in German agglomerations exceed World Health Organisation (WHO) guideline values and effect thresholds.Close to sources, pollutant levels can even be significantly higher.The situation regarding nitrogen dioxide and particulate matter has greatly improved since 2000.Ozone and particulate matter pollution is very dependent on the weather.
