摘　　要：卷烟烟气中的重金属危害人体健康。为了快速测定卷烟中烟气重金属含量,本研究采用测定烟丝与烟灰中的重金属,然后利用差减法来计算烟气中重金属的含量。结果表明,铅、镉、砷、铬4种重金属在烟气中的含量能利用减差法准确检出。减差法克服了烟气捕集器和原子吸收法的缺点,是一种操作简便、检测准确、普适性强的方法。Heavy metals in cigarette smoke can harm human health.The heavy metal content in tobacco and soot was rapidly determined by the differential subtraction to calculate the content of heavy metals in the flue gas.The results showed that the four heavy metals lead,cadmium,arsenic,chromium in the flue gas the content could be accurately detected by the leas difference method.Less difference method to overcome the shortcomings of the flue gas trap and atomic absorption spectrometry was a simple and accurate detection,pervasively.
