    • Evaluation of low-cost formaldehyde sensors calibration 

      Justo Alonso, Maria; Madsen, Henrik; Liu, Peng; Jørgensen, Rikke Bramming; Jørgensen, Thomas Berg; Christiansen, Even Johan; Myrvang, Olav Aleksander; Bastien, Diane; Mathisen, Hans Martin (Peer reviewed; Journal article, 2022)
      Low-cost sensors (LCS) are becoming ubiquitous in the market; however, calibration is needed before reliable use. An evaluation of the calibration of eight identical pre-calibrated formaldehyde LCS is presented here. The ...
    • Exposure to ultrafine particles in the ferroalloy industry using a logbook method 

      Jørgensen, Rikke Bramming; Kero, Ida; Blom, Aleksander; Grove, Esten Eide; Svendsen, Kristin V Hirsch (Peer reviewed; Journal article, 2020)
      Background: It is difficult to assess workers’ exposure to ultrafine particles (UFP) due to the lack of personal sampling equipment available for this particle fraction. The logbook method has been proposed as a general ...
    • Inflammatory effects of exposure to different stone types used in Norwegian asphalt 

      Nitter, Therese Bergh; Hilt, Bjørn; Svendsen, Kristin V Hirsch; Buhagen, Morten; Dahlman, Hans Jørgen; Øvrevik, Johan; Refsnes, Magne Arnold; Jørgensen, Rikke Bramming (SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)
      During the winter in Scandinavian countries, up to 90% of traffic-related particulate matter (PM) is from non-exhaust emissions sources such as asphalt wear. Measures to reduce urban PM have focused mainly on exhaust ...
    • Measurements of indoor air quality in four Norwegian schools 

      Justo Alonso, Maria; Jørgensen, Rikke Bramming; Mathisen, Hans Martin (SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)
      Children spend a minimum of six hours per day in Norwegian schools. Their exposure to different indoor air quality it is known to affect their performance. It is very common to use demand-controlled ventilation ...
