Survey for N-Nitroso Compounds at Uniroyal, Chicopee Falls Plant, Chicopee Falls, Massachusetts, September 22, 1978

摘要

Environmental samples were collected on September 22, 1978 to determine the workers' exposures to N-nitroso compounds, especially airborne volatile nitrosamines, at the Uniroyal tire factory in Chicopee Falls, Massachusetts. The area air samples contained N-nitrosomorpholine (NMOR) ranging from 0.03 to 0.6 micrograms per cubic meter, N-nitrosodimethylamine (NDMA) ranging from 0.03 to 0.2 micrograms per cubic meter, and N-nitrosodiethylamine (NDEA) ranging from 0.13 to 1.4 micrograms per cubic meter. The process air samples contained NMOR ranging from 0.73 to 22.0 micrograms per cubic meter. High nitrosamine concentrations were associated with heating and increasing the surface of the rubber stock. Two unknown compounds were detected and determined not to be N-nitroso compounds, but acted like O-nitroso compounds.
