Workers have a variety of occupational exposures in the metalworking fluid (MWF) industry. Two possible contaminant sources of exposure are potentially carcinogenic polycyclic aromatic hydrocarbons (PAHs) and Nnitrosamines. Although severe refining processes are required to eliminate or reduce the aromatic hydrocarbons for mineral oils used in MWFs, PAHs may still be present in the oils, or as contaminants of ancillary chemicals, or be generated over time under conditions of use.(1,2) In addition, the Occupational Safety and Health Administration and the U.S. Environmental Protection Agency have promulgated standards to prevent nitrosamine formation in new MWFs. However, nitrosamine formation may occur under certain work conditions or in the presence of nitrate-reducing microorganisms.(3,4,5,6) Current exposure concentrations for PAHs and Nnitrosamines in MWFs across the MW industry are not known.
