Particulate matter and nitrogen oxide measurement in Triesenberg

The Office of Environment measures air quality at various locations using a mobile measuring station. These measurements are carried out in addition to those at the fixed eastern air monitoring station at the National Library in Vaduz. Since 17 December 2024, the mobile air monitoring station has been located near the town hall in the center of Triesenberg and will measure air quality there for a year, focusing on particulate matter and nitrogen oxides.

Particulate matter is a mixture of the smallest dust particles with a diameter of less than 10 micrometers (abbreviated to PM10) that enter the Air from various sources. So-called primary particulate matter is created when fossil fuels (petrol, diesel, heating oil and coal) and wood are burned. Primary sources also include the proportion caused by road and tire abrasion and swirling. Secondary particulate matter can arise in the atmosphere from gaseous precursor substances that originate from combustion exhaust gases or Agriculture processes. Nitrogen oxides (abbreviated to NOx) are formed during combustion processes from oxygen and gaseous nitrogen. The main source of nitrogen oxides is road traffic.

The measured values in the center of Triesenberg can be viewed as weekly hydrographs at www.llv.li in the Air Quality section. The reports from previous years can also be found there. The concentrations of particulate matter, nitrogen oxide and ozone at the Landesbibliothek measuring station in Vaduz can also be viewed at www.ostluft.li.
