Efforts were made to determine the probability of air contaminants within 1 meter reaching the nose from either a point-source thermal generation of an aerosol or from generations of vapor by evaporation. The study also attempted to define the objective criteria for evaluation of mixing (K) factors between 1 and 10 meters of individual contaminant spaces or in an entire room. Small, thermally generated plumes were able to move with little dilution through spaces of 1 meter and more. Concentrations of acrolein and formaldehyde in side-stream cigarette smoke were tens to hundreds of times the acceptable limits. Between one and two thirds of these concentrations were associated with the particulate phase of the smoke, suggesting that aldehydes may be deposited in the respiratory system rather than absorbed in the nose and trachea, perhaps providing a pathway for bronchial cancer. Concentrations of irritants in contaminant streams sufficient to cause eye or nose/throat irritation may be measured by sampling close enough to the source to trap the entire contaminant stream.
