Evidence from tar-stain patterns in 135 cigarette filters discarded in ashtrays in public areas of shopping malls was used to estimate the prevalence of behaviorally blocked air dilution vents in ultra-low-yield cigarettes. Nineteen per cent (+/- 4, standard errors of the mean) of the filters had been blocked extremely, 39 per cent (+/- 5 SEM) had been blocked to some degree, and 42 per cent (+/- 5 SEM) had not been blocked at all. Smokers, health practitioners, and researchers need to be warned of the risks of vent blocking.
通过分析在购物中心公共区域烟灰缸中丢弃的135个香烟过滤嘴的焦油污渍模式,来估计超低焦油香烟中存在的行为性堵塞空气稀释通风口的流行情况。19%(±4,均值标准误)的过滤嘴被极度堵塞,39%(±5均值标准误)的过滤嘴有一定程度的堵塞,42%(±5均值标准误)的过滤嘴完全未被堵塞。需要向吸烟者、健康从业者和研究人员警示通风口堵塞的风险。
