title: Tobacco-specific N-nitrosamines in the saliva of habitual male snuff dippers.
abstract: Saliva was collected every ten minutes from habitual male snuff dippers and analysed for tobacco-specific N-nitrosamines (TSNA). Detectable levels of at least two TSNA were found in all samples collected between 10 and 30 minutes after the snuff had been placed in the mouth. Total concentrations of TSNA up to 241 ng/g were found in the saliva. Trace levels of TSNA were still found in the saliva 20 minutes after the snuff had been removed.
