Quantitation of urinary volatile nitrosamines from exposure to tobacco smoke.
A sensitive and selective method was developed and validated to detect six volatile nitrosamines (N-nitrosodimethylamine, N-nitrosomethylethylamine, N-nitrosodiethylamine, N-nitrosopiperidine, N-nitrosopyrrolidine and N-nitrosomorpholine) in human urine. This method uses a liquid-liquid extraction cartridge followed by analysis with gas chromatography-tandem mass spectrometry (GC-MS-MS) and qua...
متن کاملDetermination of Tobacco Specific Nitrosamines in Cigarette Mainstream Smoke – Gc-tea Method
Between 1999 and 2005, a Task Force composed of CORESTA members has studied the existing methodologies for the determination of the Tobacco Specific Nitrosamines (TSNAs) in the mainstream smoke of cigarettes. Several methods have been proposed for this determination, which are mainly based on two types of analytical methodologies: GC-TEA (Gas Chromatography with a Thermal Energy Analyser as det...
متن کاملTobacco-specific nitrosamines, an important group of carcinogens in tobacco and tobacco smoke.
Tobacco-specific nitrosamines are a group of carcinogens that are present in tobacco and tobacco smoke. They are formed from nicotine and related tobacco alkaloids. Two of the nicotine-derived nitrosamines, NNK and NNN, are strong carcinogens in laboratory animals. They can induce tumors both locally and systemically. The induction of oral cavity tumors by a mixture of NNK and NNN, and the orga...
متن کامل[Strategies for reducing risks in smoking: opportunity or threat].
The smoking control policies recommended by the World Health Organisation have achieved a slight decrease in smoking prevalence in the developed countries, although associated mortality is still very high. The use of tobacco products other than cigarettes and even medicinal nicotine (known as nicotine replacement therapy (NRT)) has been proposed as a risk reduction strategy. Among the tobacco p...
متن کاملEvidence supporting product standards for carcinogens in smokeless tobacco products.
Smokeless tobacco products sold in the United States vary significantly in yields of nicotine and tobacco-specific nitrosamines (TSNA). With the passage of the Family Smoking Prevention and Tobacco Control Act, the Food and Drug Administration now has the authority to establish product standards. However, limited data exist determining the relative roles of pattern of smokeless tobacco use vers...
