Worker exposures to N-nitroso compounds were determined at the Blue Side Tannery (SIC-3111) in St. Joseph, Missouri, on January 16, 1979. The survey was part of an NIOSH study of worker's exposure to N-nitroso compounds in various industrial settings. The company employed about 134 workers. Twenty one air samples and eight bulk samples were collected and analyzed for N-nitroso compounds and their precursors. N-nitrosodimethylamine (62759) (NDMA) was present in all interior air samples, and ranged from 0.2 to 2.1 micrograms per cubic meter. None of the process water bulk samples contained measurable amounts of NDMA, although 1.4 to 2.5 micrograms per milliliter of NDMA were found after nitrosation of three of the eight samples. All of the morpholine spiked thermosorb tubes contained N-nitrosomorpholine (59892), indicating the presence of a nitrosating agent in the air.
