I have been breathing ethanol with a level of 2,759 ug/m3 at work. This has been going on for over 7 months in a small room (5 x 8). I have been to the doctor and been diagnosed with acute bronchitis. For the last three months I have only been at my job for 20 minutes at the most. When I walk in I start getting dizzy and leave with a headache. My boss has told me that the amount of ethanol I'm breathing should not affect my health. Is this true?
