在人际交往中,敬别人一支烟,常被认为是礼貌,何况在暂短时间内吸烟还有提神、减轻疲劳等效果。因此在短期内要求让大多数吸烟者都不吸烟是很难实现的。这就有必要采取一些权宜之计来减少吸烟对人身体的危害。 香烟上的过滤嘴是用酸性纤维制成的,它对苯并芘的过滤效率为59％,对烟硷的过滤效率为20～30％,粗略估计,每两支有过滤嘴的烟,约相当于一支无过滤嘴的烟。过滤嘴燃烧不充分,从而产出更多的一氧化碳,使人血液中的一氧化碳较吸无过滤嘴烟者要高20％。一氧化碳气与血红蛋白的结合能力是氧的200倍,烟中的一氧化碳气与氧
In interpersonal relationships, respect others a cigarette, often considered to be polite, not to mention smoking in the short period there refreshing, reduce fatigue and other effects. Therefore, in the short term, it is very hard for most smokers to smoke. It is necessary to take some expedient measures to reduce the harm of smoking on the human body. The filter on the cigarette is made of acidic fiber, which has a filtration efficiency of 59% for benzopyrene and a filter efficiency of 20-30% for nicotine. It is roughly estimated that for every two cigarettes with filter, it is equivalent to A filterless cigarette. The filter burns inadequately, producing more carbon monoxide, giving people 20% more carbon monoxide in their blood than smokers and smokers do. Carbon monoxide gas and hemoglobin is 200 times the binding capacity of oxygen in the carbon monoxide gas and oxygen
