对河南不同产地、津巴布韦和巴西的烤烟做静燃速率测定 ,并分析与矿质元素中的Cl-,K2 O ,SO4 2 -,有效钾及K/Cl等的相关关系 ,以及对烟气中焦油、烟气烟碱、CO等有害成分释出量的影响 .结果表明 ,河南不同产地烤烟静燃速率整体水平低于津巴布韦、巴西 .静燃速率与Cl-1,SO4 2 -呈显著负相关 ;与K2 O、有效钾、K/Cl为显著正相关 ;对焦油、烟气烟碱、CO呈极显著负相关 ,说明烤烟烟叶不同的矿质元素含量决定了静燃速率的高低进而对烟气中有害成分含量有明显影响
The static burning rate of flue-cured tobacco in different producing areas in Henan, Zimbabwe and Brazil was measured and the correlations with Cl-, K2O, SO42-, available potassium and K / Cl in mineral elements were analyzed, , Fume nicotine, CO and other harmful components.The results showed that the overall level of quasi-burning rate of flue-cured tobacco in different areas of Henan was lower than that of Zimbabwe and Brazil, and there was a significant negative correlation between the quiescent rate and Cl-1 and SO42- And K2O, available potassium and K / Cl were significantly and positively correlated; tar, flue gas nicotine, CO was significantly negatively correlated, indicating that the different mineral elements in flue-cured tobacco leaves determine the level of static burn rate and then flue gas Harmful ingredients have a significant impact
