exposure to second hand smoking
The duration of the exposure to second hand smoke both days was for 20 minutes within a 250mgr/m3 concentration box room. A smoking machine was used, which mimics the smoker (up to 6 breaths per minute in tobacco volume 80ml for each inhalation). The exposure was sometimes with closed mouth and others with closed nose in random sequence.
