The mobile air measuring station is now back in Eschen – Liechtenstein
ESCHEN – The mobile air measuring station has been located at the Eintrachtkreisel on Essanestrasse in Eschen since Tuesday, where it will record the air quality for a year. The Office for the Environment announced this on Thursday.
The Office for the Environment (AU) uses a mobile measuring station to measure the air quality at various locations. These measurements are carried out in addition to those at the fixed eastern air measuring station in Vaduz. Next year, the mobile measuring station will be back in Eschen with a focus on fine dust and nitrogen oxides.
Nitrogen oxides, or Nox for short, are created during combustion processes at high temperatures from atmospheric oxygen and gaseous nitrogen. Road traffic is the main source of nitrogen oxides. Passive collector measurements show relatively high nitrogen oxide concentrations on Essanestrasse, according to the AU. Measures resolved over time should now make it possible to examine this situation more closely with the daily and weekly progressions.
Fine dust is also measured
Furthermore, the station also measures the fine dust concentration in the air. Fine dust is a mixture of the smallest dust particles with a diameter of less than 10 micrometers and therefore also called PM10 (English: particulate matter). Fine dust enters the air as primary fine dust from various sources through the combustion of fossil fuels such as gasoline, diesel, heating oil or coal and the combustion of wood. The primary sources also include the amount caused by abrasion and resuspension. In addition, so-called secondary fine dust forms in the atmosphere from combustion exhaust gases and agricultural processes.
Note: You can use the measured values in ash here call up as weekly progression curves.
