Concentrations of the irritants formaldehyde and acrolein in side stream cigarette smoke plumes are up to three orders of magnitude above occupational limits, readily accounting for eye and nasal irritation. "Low-tar" cigarettes appear at least as irritating as other cigarettes. More than half the irritant is associated with the particulate phase of the smoke, permitting deposition throughout the entire respiratory tract and raising the issue of whether formaldehyde in smoke is associated with bronchial cancer.
侧流香烟烟雾羽流中刺激性物质甲醛和丙烯醛的浓度比职业接触限值高出多达三个数量级,很容易导致眼睛和鼻腔受到刺激。“低焦油”香烟似乎至少与其他香烟一样具有刺激性。超过一半的刺激性物质与烟雾的颗粒相有关,这使得它们能够在整个呼吸道沉积,并引发了烟雾中的甲醛是否与支气管癌有关的问题。
