The method used for the measurement of dust deposition is the standard Bergerhoff method with the corresponding collection instrument. The measurement points of the Bergerhoff network are almost always located near industrial sites known for their high dust emissions (e. g. steel and metal-producing industries).

The telemetry network consists of fixed and mobile measuring stations throughout Luxembourg located in rural, urban or peri-urban areas. The network measures air quality in real time and monitors the levels of key pollutants, including nitrogen dioxide, ozone and fine particulate matter. This network serves as a basis for informing and alerting the population, especially the sensitive people in case of pollution peaks. It is also in the context of improving public information that an app on air quality has been developed.

Particulate matter consists of any particles suspended in ambient air. In general, they consist of a complex mixture of substances of different sizes and characteristics, depending on the origin of emissions. In addition to the measurements of particulate matter in the telemetry network, which are used to inform the population in real time, PM10 and PM2.5 particulate matter are also measured by the filter reference method. Differences between the results of telemetry network measurements and those obtained with the reference method are due to different measurement methods.
