Hierarchical Composites to Reduce N-Nitrosamines in Cigarette Smoke
نویسندگان
چکیده
In order to reduce the harmful constituents in cigarette smoke, two hierarchical composites were synthesized. Based on, zeolites HZSM-5 or NaY fragments were introduced into the synthetic system of mesoporous silica SBA-15 or MCM-41 and assembled with the mesoporous materials. These porous composites combine the advantages of micro- and mesoporous materials, and exhibit higher effects than activated carbon on reducing tobacco specific nitrosamines (TSNA) and some vapor phase compounds in smoke.

The case of the disappearing nitrosamines: a potentially global phenomenon.
The cigarette usually carries in its smoke significant doses of carcinogenic tobacco specific nitrosamines (TSNAs), which have been implicated as causes of oral, lung, oesophageal, and pancreatic cancer. However, there is substantial variation in nitrosamine content of the smoke of modern cigarettes. This variation is both unacceptable and unnecessary, as TSNAs can be readily removed during the...
متن کاملSmoke yields of tobacco-specific nitrosamines in relation to FTC tar level and cigarette manufacturer: analysis of the Massachusetts Benchmark Study.
OBJECTIVES This research assessed the relationship between the deliveries of carcinogenic tobacco-specific nitrosamines (TSNAs) and the Federal Trade Commission (FTC) "tar" ratings of US commercial cigarettes. METHODS Analysis of covariance (ANCOVA) was used to assess the explanatory power of FTC tar, the particular manufacturer, and other cigarette characteristics to predict the yields of fo...
متن کاملAn analysis of the role of tobacco-specific nitrosamines in the carcinogenicity of tobacco smoke.
Cigarette smoke is a complex mixture consisting of more than 4500 chemicals, including several tobacco-specific nitrosamines (TSNA). TSNA typically form in tobacco during the post-harvest period, with some fraction being transferred into mainstream smoke when a cigarette is burned during use. The most studied of the TSNA is 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK). NNK has been show...
متن کاملE-cigarette smoke damages DNA and reduces repair activity in mouse lung, heart, and bladder as well as in human lung and bladder cells
E-cigarette smoke delivers stimulant nicotine as aerosol without tobacco or the burning process. It contains neither carcinogenic incomplete combustion byproducts nor tobacco nitrosamines, the nicotine nitrosation products. E-cigarettes are promoted as safe and have gained significant popularity. In this study, instead of detecting nitrosamines, we directly measured DNA damage induced by nitros...
متن کاملAssessment of tobacco-specific nitrosamines in the tobacco and mainstream smoke of Bidi cigarettes.
Bidi cigarettes, or bidis, are a tobacco product that originated in India and have been gaining popularity in the USA during the past few years, particularly with adolescents. As with conventional cigarettes, tobacco and smoke from bidis contain chemical constituents including carcinogenic chemicals such as the tobacco-specific nitrosamines (TSNAs). To help better assess the potential public he...
