Abstract Forty United States facilities involved in manufacture of azo dyes (SIC-2865), fish processing (SIC-2077), rubber (SIC-3069), tanning (SIC-3111), detergents (SIC-2841), and surfactants (SIC-2843) were investigated to determine N-nitroso compounds in the environment. A gas chromatograph and high pressure liquid chromatograph system was used with sample detection by a TEA Analyzer designed for the detection of subnanogram amounts of N-nitroso compounds. The prime criteria for the selection of an industry to be surveyed were the possible formation of N-nitroso compounds from their precursors, and the use of products suspected of being contaminated with these compounds. The two industries of major concern were rubber and tanning. The authors conclude that removal of dimethylamine-sulfate (21249138) from the dehairing process in tanneries would greatly reduce the N-nitrosodimethylamine concentrations. The rubber industry requires substitution and engineering controls to reduce airborne concentrations of nitrosamines.
