【摘要】 选择某品牌香烟3种产品,分别测定香烟主流烟雾中SO2、NOx和甲醛的含量。3种污染物分别采用盐酸副玫瑰苯胺比色法、盐酸萘乙二胺比色法和乙酰丙酮光度法测定。结果表明,3种香烟主流烟雾的SO2质量浓度分别为15.76mg/m3、19.21mg/m3、20.22mg/m3;NOx的质量浓度分别为2.02mg/m3、1.60mg/m3、1.70mg/m3;甲醛的质量浓度分别为4.28mg/m3、4.68mg/m3、5.68mg/m3。香烟烟雾中SO2、NOx和甲醛的浓度较高,远高于这些有害物质引起机体损伤的阈浓度,长期接触会对机体产生确定性损伤效应。更多还原

【Abstract】 The article has done a detailed measurement and testing of the content of SO₂, NO_x and formaldehyde in cigarette smoking by selecting a kind of cigarette and doing the corresponding research. The results of our research can be shown as follows: in Sample 3, Sample 2 and Sample 1 of tobacco smoking, the consistency of SO₂ is 15.76 mg/m³, 19.21 mg/m³ and 20.22 mg/m³; the consistency of NO_x is 2.02 mg/m³, 1.60 mg/m³, 1.70 mg/m³; and the consistency of formaldehyde is 4.28 mg/m³, 4.68 mg/m³, 5.68 mg/m³. Thus, it has been verified that the consistency of SO₂, NO_x and formaldehyde in tobacco smoking is higher than the threshold consistency of the three kinds of substance.更多还原
