We carry out environmental surveys in both outdoor and indoor environments, including sampling, analysis, and consultancy. We are accredited for measurements of emissions to air, and determination of a variety of emission parameters and components. We also perform environmental surveys of buildings, indoor climate and occupational hygiene.
Dust measurements in ambient air
SINTEF Norlab conducts dust measurements ambient air quality, comprising online measurements of particulate matter (PM10 and PM2,5) and sampling of dust deposition.
Air quality regulations
In recent years, the authorities have had an increasing focus on air quality. The scope, as well as the parameters that should be measured, are described in the Norwegian regulations and guidelines related to local air quality.
Measurements of dust deposition is usually performed in areas with a known industrial source such as quarries, and in construction work areas, and the sampling period is one month. We perform sampling and determination of dust deposition according to NS4852. In addition to total particulate matter, the content can be analysed for the presence of characteristic metals or other components.
Airborne particulate matter (PM10 and PM2,5)
PM10 og PM2,5 is usually measured continuously using fine dust aerosol spectrometers. SINTEF Norlab has extensive experience with the deployment and operation of such instruments.
