Abstract : The NO2 levels permitted aboard submarines are 0.5 ppm for 90 days, 1 ppm for 24 hours and 10 ppm for 1-hour. The 90 day limit 'represents an average value for continuous exposure which may be temporarily exceeded so long as there are corresponding periods of low concentrations'. The 24-hour limit 'represents an emergency level and is not to be repeated until all affected personnel have completely recovered.' The 1-hour limits are 'not to be exceeded' and are 'not for extrapolation to other exposure times'. The purpose of this study was to obtain information on both ambient and personal levels of NO2 during the course of a long submerged period. An effort is then made to access these measured levels with regard to their possible short and long-term health effects on submariners.
