摘要
目的检测20种主要国产品牌香烟主流烟雾中多环芳烃与焦油含量,并分析其是否有相关关系。方法按ISO国际标准吸取香烟主流烟雾中颗粒物,提取颗粒物中的多环芳烃,高效液相法测定荧蒽(FLUO),芘(pyrene熏PY),苯并(g熏h熏j)(BGP),苯并(a)蒽眼B穴a雪A演,(CRY)熏苯并(a)芘眼B穴a雪P演,苯并(b)荧蒽眼B(b)F演,苯并(k)荧蒽眼B(k)F演,二苯并(a熏h)蒽(DBA)9种多环芳烃含量,并检测烟雾中焦油、尼古丁含量。结果20种主要品牌香烟主流烟雾中多环芳烃主要成分含量均值从高到低依次为芘,荧蒽,CRY,苯并(a)蒽,二苯并(a熏h)蒽,苯并(a)芘,苯并(g熏h熏j),苯并(b)荧蒽熏苯并(k)荧蒽。总PAHs平均含量为714.8ng/支,其中芘、荧蒽等非致癌性组分占总PAHs的93%;致癌性多环芳烃平均含量为89.4ng/支,以苯并(a)芘和二苯并(a熏h)蒽为主要成分。总PAHs、致癌性PAHs含量与焦油含量的相关系数和P值分别为0.647,0.002,0.554,0.011。结论国产香烟主流烟雾中均可检出9种多环芳烃,总PAHs、致癌性PAHs含量与焦油含量呈正相关,提示焦油可作为估计烟雾中致癌多环芳烃含量、评价健康危害的指标。
Objective To analyze the content of polycyclie aromatic hydrocarbons （PAHs） in mainstream smoke of 20 brands of Chinese cigarette. Methods Mainstream smoke of 20 brands of Chinese cigarettes were collected by ASM51 smoking machine. Both tar and nicotine were analysed in the same time. Nine kinds of PAHs, fluoranthene, pyrene, benzo（a）anthracene, chrysene, benzo（a）pyrene, bonzo（b）fluoranthene, benzo（k）fluoranthene, benzo（g, h, j）perylene and dibenzo（a, h）anthracene, in mainstream smoke from each brand were determined with HPLC. Results Total PAHs ranged from 404.1 to 1085 ng per cigarette with an average of 714.8 ng per cigarette. Non-carcinogenic PAHs accounted for 93% of total PAHs. Carcinogenic PAHs ranged from 49.4 to 117.7 ng per cigarette, averaging 89.4 ng per cigarette. Content of tar, not nicotine, was significantly related to either total PAHs or carcinogenic PAHs. Conclusion Significant correlation between tar and PAHs suggests that tar may be a predictor of carcinogenic PAHs in mainstream smoke of Chinese cigarettes and a parameter to assess the impact of Chinese cigarettes on health.
