Bennett, G

Groups of 6 men were exposed to 0.2 or 0.5 ppM O/sub 3/ for 3 hr/day, 6 day/wk, for 12 wk in room. No changes were observed in FVC or FEV/sub 1/ /sub 0/ in low group but lowered FEV/sub 1/ /sub 0/ was observed in high group (return to normal at 6 wk). Low FEV with steady FVC indicates obstruction of terminal bronchi and bronchioles. Smoking was not controlled. There is the presence of O/sub 3/ belt, especially in stratosphere reaching 12 ppM (volume) at 90,000 ft. Higher concentrations occur in spring and at higher latitudes. O/sub 3/ in cabin of passenger aircraft increased above tropopause to a maximum of 0.065 ppM at 41,000 ft in one type of plane (Comet) and 0.12 ppM at 39,000 ft in Boeing 707 Conway. SST contents would be somewhat higher but could be reduced by a longer hold-up time in pressurization (heat activation).
