A series of low tar cigarettes (LTC) were smoked and the quantities of condensable mainstream (inhaled) and sidestream (between puffs) smoke compounds were determined and compared to those produced by a high tar, nonfilter cigarette. It was found that the LTC produced large quantities of sidestream smoke condensates, about equal to the high tar cigarette, and contained very high levels of toxic or cocarcinogenic phenols. On an equal weight basis, the LTC emitted more of these hazardous compounds into sidestream and environmental tobacco smoke. Higher smoke yields of a flavor additive and a sugar degradation product indicated addition of such compounds during the manufacture of LTC. It was concluded that, compared to a high tar cigarette, smoking LTC may be better for the smoker, but not for the nearby nonsmoker. Information should be developed to allow smokers to choose LTC that produce lower levels of hazardous compounds in their environmentally emitted sidestream smoke.
对一系列低焦油香烟（LTC）进行了抽吸，并测定了可冷凝主流（吸入）和侧流（抽吸间隙）烟雾成分的含量，并与高焦油无滤嘴香烟产生的烟雾成分进行了比较。结果发现，LTC产生大量的侧流烟雾冷凝物，与高焦油香烟产生的冷凝物量大致相当，并且含有非常高含量的有毒或致癌酚类物质。在同等重量的基础上，LTC向侧流和环境烟草烟雾中排放了更多此类有害化合物。一种调味添加剂和一种糖降解产物的烟雾产量较高，表明在LTC制造过程中添加了此类化合物。得出的结论是，与高焦油香烟相比，吸食LTC对吸烟者可能更好，但对附近的非吸烟者则不然。应提供相关信息，以便吸烟者能够选择在环境排放的侧流烟雾中产生较低水平有害化合物的LTC。
