Clearly, a sound evaluation of the total mutagenic/carcinogenic potencies of a complex mixture of POM emissions (e.g., diesel exhaust) should include not only the PEFs of the primary particle- and vapor-phase PAHs and PACs but also those of the mutagens formed in atmospheric reactions of precursor PAHs (see, for example, Arey et al. (1992), Lewtas (1993b), Atkinson and Arey (1994), Nielsen et al. (1996), Arey (1998a), and Section F). For examples of such formal scientific health risk assessments prepared by the State of California Air Resources Board and Office of Environmental Health Hazard Assessment, see Benzo[ ]pyrene as a Toxic Air Contaminant (CARB, 1994) and Identification of Diesel Exhaust as a Toxic Air Contaminant (CARB, 1998).

The Office of Environmental Health Hazard Assessment, California Environmental Protection Agency, has developed an inhalation reference exposure level of 50ppb (300 pgm ) based on a whole-body inhalation study in rats, 7hday, 5 days week for 6 months. The critical effects are pathological changes in the liver and kidney, with an (average experimental exposure) LOAEL of 5.3 ppm, and a total uncertainty factor of 300. 

International occupational exposure limits (OELs) for NMP generally range between 5 and 50 ppm as an 8h time-weighted average (TWA). The American Conference of Governmental Industrial Hygienists has not established an 8 h TWA OEL for NMP. Several countries have established a short-term excursion limit of 75 ppm. The California Office of Environmental Health Hazard Assessment has identified NMP as a reproductive toxin and established maximum allowable daily limits for exposure of 3200 pg day (via inhalation) and 17 000pgday ...
