RELATIONSHIP BETWEEN N-NI-TROSAMINES CONTENT IN SMO-LDERING SMOKES AND TAR ALONG WITH NICOTINE IN CIGARETTE

测定了市售各种烤烟型和混合型卷烟阴燃烟气中亚硝胺的含量 ,并探讨了与卷烟焦油和烟碱量的关联 .实验证明 :降低焦油对于减少卷烟阴燃烟气中亚硝胺含量的作用很有限 ,而采用选择性吸附

N-Nitrosamines content of cigarette smoldering smoke in different brands were examined and investigated together with the marked content of tar and nicotine in cigarette. The results demonstrated that the content of N-nitrosamines in the smoldering smoke of cigarette was not obviously related to the marked content of tar or nicotine. Therefore it was better to use novel additive or microwave radiation than to decrease tar content in the cigarette for removal of N-nitrosamines from the smoke.
