Researchers in the nitrosamine field were contacted on their views of the TEA analyzer and the ThermoSorb/N Air Sampler for nitrosamine analysis. Fifty-eight vehicle interiors were sampled to determine the effects of vehicle type, vehicle age, mode of operation, and ambient conditions on interior nitrosamines. Nitrosamines were found in passenger cars, station-wagons, passenger and cargo vans, pickup trucks, and in new and used heavy-duty trucks, but not in motor homes. The average daily intake of nitrosamines from vehicle interiors for a commuter in a vehicle 3 hours/day was estimated to be less than that from a can of beer or from a strip of bacon.
