Correlations of Ammonia in Mainstream Cigarette Smoke with Ammonia,Nitrite and Nitrate in Tobacco Leaf

In order to investigate the correlations between the delivery of ammonia in mainstream cigarette smoke and the contents of nitrite,nitrate and ammonia in tobacco leaf,the delivery of ammonia in mainstream smoke and the contents of nitrite,nitrate and ammonia in 18 samples of flue-cured tobacco leaves from different stalk positions from Shandong,Yunnan and Fujian in 2007 and 2008 and 3 imported leaf samples were determined by ion chromatography.The simple correlation analysis was conducted and the significance of correlation was tested.The results showed that the delivery of ammonia in mainstream cigarette smoke significantly positively correlated with the content of nitrite in tobacco leaves,while its correlations with nitrate and ammonia were not significant.
