Short-term lung function decline in tunnel construction workers.
Ulvestad B, Lund MB, Bakke B, Thomassen Y, Ellingsen DG. Ulvestad B, et al. Among authors: thomassen y. Occup Environ Med. 2015 Feb;72(2):108-13. doi: 10.1136/oemed-2014-102262. Epub 2014 Oct 30. Occup Environ Med. 2015. PMID: 25358744
Previous studies carried out in the 1990s showed that tunnel construction workers were at increased risk of both short-term and long-term lung function decline. Since then, efforts have been made to reduce exposure. The objective of the present study was to investig …

Characterisation of occupational exposure to air contaminants in a nitrate fertiliser production plant.
Hovland KH, Thomassen Y, Skaugset NP, Skyberg K, Skogstad M, Bakke B. Hovland KH, et al. Among authors: thomassen y. J Environ Monit. 2012 Aug;14(8):2092-9. doi: 10.1039/c2em30370a. Epub 2012 Jul 10. J Environ Monit. 2012. PMID: 22777595
Exposures to NH(3), CO and NO(2) were measured using direct-reading electrochemical sensors and the time weighted overall averages were all below the LODs of the respective sensors, NH(3) 2 ppm; CO 2 ppm; and NO(2) 0.2 ppm, but some short-term peaks were detected. Even tho …

A neurobehavioral study of chloralkali workers after the cessation of exposure to mercury vapor.
Bast-Pettersen R, Ellingsen DG, Efskind J, Jordskogen R, Thomassen Y. Bast-Pettersen R, et al. Among authors: thomassen y. Neurotoxicology. 2005 Jun;26(3):427-37. doi: 10.1016/j.neuro.2005.03.006. Epub 2005 Apr 26. Neurotoxicology. 2005. PMID: 15935213
However, the difference in the Digit Symbol Test scores between the two occasions was associated with the concentration of inorganic mercury in whole blood while they were still under exposure. The results suggest that no long-term effects of mercury vapor exposure are fou …
