title: Occurrence of and exposure to N-nitroso compounds in tobacco.
abstract: The concentrations of 21 N-nitroso compounds in smokeless tobaccos are presented. Tobacco-specific nitrosamines accounted for 70-90% of the total identified N-nitroso compounds. Daily exposure of smokeless tobacco users to preformed N-nitroso compounds may exceed 200 micrograms/day in certain populations.
