丁酸乙酯对卷烟烟气的影响

为研究丁酸乙酯对卷烟烟气的影响,在模拟卷烟燃烧条件下对其进行热裂解实验;按照不同用量加入空白卷烟,测试主流烟气中7种有害成分(CO、HCN、NNK、Ba]P、巴豆醛、苯酚和氨)的释放量以及烟气粒相物的细菌致突变性、体外细胞毒性和体外微核率。结果表明:①丁酸乙酯在模拟卷烟燃烧温度条件下的热解行为主要是原形转移;②与空白卷烟相比,加入丁酸乙酯后7种烟气有害成分的释放量无显著增加;③3种不同剂量丁酸乙酯分别加入空白卷烟后,烟气粒相物的细菌致突变性、体外细胞毒性及体外微核测定结果均无显著增加。 

Effects of Ethyl Butyrate Addition on Cigarette Smoke

In order to assess the effects of ethyl butyrate addition on cigarette smoke,ethyl butyrate was pyrolyzed under conditions simulated cigarette combustion.Cigarette samples added with different rates of ethyl butyrate were prepared,and the deliveries of seven harmful components,including carbon monoxide,hydrogen cyanide,NNK,Ba]P,crotonaldehyde,phenol and ammonia,in mainstream cigarette smoke were determined,the bacterial mutagenicity,in vitro cytotoxicity and micronucleus testing of smoke particulate matter were conducted separately.The results showed that:1) The pyrolysis behavior of ethyl butyrate mainly was intact transfer under simulated cigarette combustion conditions.2) Comparing with the control cigarettes,the deliveries of the seven harmful components in mainstream smoke of tested cigarettes did not increase significantly.3) The results of bacterial mutagenicity,in vitro cytotoxicity and micronucleus assays of smoke particulate matter did not change significantly after ethyl butyrate addition.
