抄録

The following simple method was devised for analyzing N-nitrosamines in the side-stream smoke from cigarette. N-Nitrosamines in the side-stream smoke are collected by passing it through an impinger containing 0.5 M sulfamic acid, a desiccant tube (Na2CO3) and Thermo Sorb/N tube, successively. N-Nitrosamines collected are extracted from each port of the collection system by dichloromethane, and the extracts are gathered together. After adding a known amounts of N-nitrosodi-n-butylamine as an internal standard, the extracts are concentrated to about 0.5 ml by the K-D condenser and by gentle evaporation under nitrogen stream. NNitrosamines in the concentrate are analyzed by a gas chromatography with TEA analyzer.<BR>The collection efficiency and its coefficient of variation in this method were 100% and 7.2% for N-nitrosodimethylamine (NDMA) and 100% and 8.1% for N-nitrosopyrrolidine (NPYR).<BR>This method was applied to NDMA and NPYR analysis in the side-stream smokes from 15 Japanese and 15 foreign brands of cigarettes. N-Nitrosamines contents were largely depended on its brands, and ranged from 113 to 544 ng/cigarette for NDMA and 40 to 332 ng/cigarette for NPYR. Chinese cigarettes emmited fairly lower N-nitrosamines than those of the other countries. NDMA and NPYR emmited from American cigarettes tested were larger than those from Japanese cigarettes.
