Tobacco-specific nitrosamines (TSNAs) are N-nitroso-derivatives of pyridine-alkaloids (eg,
nicotine) present in tobacco and cigarette smoke. Two TSNAs, N′-nitrosonornicotine (NNN) …

Tobacco-specific N-nitrosamines (TSNA) include 4-(methylnitrosamino)-1-(3-pyridyl)-1-
butanone (NNK), N′-nitroso nornicotine (NNN), N′-nitroso anabasine (NAB) and N …

Tobacco-specific nitrosamines are the most abundant strong carcinogens in smokeless
tobacco products. This chapter focuses on three of the most important of these compounds …

Chemical-analytical studies during the past 4 years led to several new observa tions on the
formation of tobacco-specific A-nitrosamines (TSNA) and their occurrence in smokeless …

Cigarette smoke is a complex mixture of chemicals, including several tobacco-specific
nitrosamines (TSNA). Most TSNA are formed in tobacco during the post-harvest period …

New tobacco products, designed to attract consumers who are concerned about the health
effects of tobacco, have been appearing on the market. Objective evaluation of these …

Background: Smokers are exposed to significant doses of carcinogens, including tobacco-
specific nitrosamines (TSNA). Previous studies have shown significant global differences in …

N′-Nitrosonornicotine (NNN) was the first tobacco-specific nitrosamine (TSNA) identified as
carcinogen in tobacco smoke, but no data exist on in vivo interactions between NNN and …
