WebBenzene has a sweet, aromatic, gasoline-like odor. Most individuals can begin to smell benzene in air at 1.5 to 4.7 ppm. The odor threshold generally provides adequate warning for acutely hazardous exposure concentrations but is inadequate for more chronic exposures. METHODS OF DISSEMINATION: WebThe lowest level at which humans can detect the odor of ammonia is ~ 5-10 ppm v/v, (odor threshold) and this generally provides sufficient warning of exposure; however, persons with prolonged exposure to ammonia will lose their … Webthreshold data; an odor threshold range of 0.0005–0.010 ppm was reported. Guidotti (1994) reported an odor threshold range of 0.01–0.3 ppm. Since high concentrations of hydrogen sulfide (150–200 ppm) can paralyze the olfactory nerve, odor may not be a reliable indicator of the presence of this gas (Beauchamp et al. 1984).
