目的检测装有三层颗粒过滤嘴的卷烟滤嘴切割面上的活性炭颗粒，以确定滤嘴上的活性炭颗粒是否在吸烟过程中释放出来。在不将香烟从包装中取出的情况下，用立体变焦显微镜检查过滤嘴的炭颗粒。定义了具有木炭颗粒的香烟的百分比，并对每个过滤嘴上的木炭颗粒进行计数。然后由同意的成年吸烟者抽随机选择的香烟，以评估在吸烟期间是否释放了活性炭颗粒。Lark香烟用常规香烟保持器抽吸，所述香烟保持器被配置成包含在线膜。吸烟后，膜进行了分析，在显微镜下的炭颗粒和其他组件的过滤器，已被释放在smoking.ResultsCharcoal颗粒中观察到79.8%（319/400）的香烟检查。每支香烟的颗粒数为3.3（SD 3.7）。接装纸（过滤嘴周围的包装纸）之间的间隙经常可见（70%; 242（71）; n = 400支香烟）。此外，木炭腔约60%是空的。对于所有吸烟者（n = 8/8），在吸烟过程中释放了活性炭颗粒。碳颗粒捕获的膜上的数量为22.5（16.2）每cigarettes.ConclusionsCharcoal颗粒纳入香烟过滤嘴，以帮助在香烟烟雾中去除毒素。在对Lark（一种带有木炭过滤嘴的流行美国香烟）的研究中，在过滤嘴表面上观察到木炭颗粒，并且当香烟被抽吸时从过滤嘴释放。在吸烟过程中，含毒素的木炭颗粒被吸入或摄入。吸入或摄入碳颗粒的具体不良健康影响尚未得到解决;然而，作为受过教育的消费者，应告知吸烟者可能的健康风险。
ObjectiveTo inspect cigarettes with a triple granular filter for charcoal granules on the cut filter surface and, if present, to determine whether the charcoal granules on the filter are released during smoking.Design400 Lark cigarettes in 20 packs were examined individually by each of three investigators for the presence of charcoal granules on the cut surface of the cellulose acetate filter. Without removing the cigarettes from the pack, the filters were examined with a stereo zoom microscope for charcoal granules. The percentage of cigarettes that had charcoal granules was defined, and charcoal granules on each filter were counted. Randomly selected cigarettes were then smoked by consenting adult smokers to assess whether the charcoal granules were released during smoking. Lark cigarettes were smoked with a conventional cigarette holder that had been configured to contain an in-line membrane. After smoking, the membrane was analysed microscopically for charcoal granules and other components of the filter that had been released during smoking.ResultsCharcoal granules were observed in 79.8% (319/400) of the cigarettes examined. The number of granules per cigarette was 3.3 (SD 3.7). Gaps between the tipping papers—the wrapping papers that surround the filter—were often seen (70%; 242 (71); n = 400 cigarettes). Further, the charcoal cavity was about 60% empty. For all smokers (n = 8/8), charcoal granules were released during smoking. The number of charcoal granules captured on the membranes was 22.5 (16.2) per cigarette.ConclusionsCharcoal granules are incorporated into cigarette filters to aid in removing toxins in cigarette smoke. In studies of Lark, a popular American cigarette with a charcoal filter, charcoal granules were observed on the filter surface, and were released from the filter when the cigarettes were smoked. During smoking, the toxin-containing charcoal granules are inhaled or ingested. The specific adverse health effects of inhaling or ingesting carbon granules have not been addressed; nevertheless, the smoker, as an educated consumer, should be informed of the possible health risks.
