Click to enlargeArsenic 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.
Arsenic emissions are mainly of anthropogenic origin, e.g they occur when stone coal, brown coal or mineral oil is combusted. Another source is the metal industry. Arsenic can also be emitted at volcanic eruptions.
Arsenic can be absorbed through the lungs and the gastrointestinal tract. After chronic absorption through the lungs the mucous membranes and airways are damaged and lung cancer may occur.
There is an Europe-wide target value of 6 ng/m³ as annual mean that is valid since 1 January 2013.
Since 2007 the target value was seldom exceeded, at stations in the vicinity of industry only.
The average pollution in urban is about 0.5 ng/m³ in urban areas slightly lower. A bit higher concentrations are measured close to industrial areas, here the average value is about 1,3 ng/m³. The lowest concentrations are measured at the very remote stations of the Environment Agency (0.3 ng/m³).
Here the annual tabulations from 2007 onwards can be found (station-by-station).
The UBA’s motto, For our environment (“Für Mensch und Umwelt”), sums up our mission pretty well, we feel. In this video we give an insight into our work.
