WebChlorine is a greenish-yellow gas that is slightly soluble in water. (4) Chlorine has a suffocating odor; the odor threshold is 0.31 ppm. (7) The chemical formula for chlorine is Cl 2, and its molecular weight is 70.90 g/mol. (4) Conversion Factors: To convert concentrations in air (at 25°C) from ppm to mg/m 3: mg/m 3 = (ppm) × (molecular ... • The threshold value is the concentration at which an aroma or taste can be detected (air, water and fat). • The recognition threshold or arousal threshold of olfactory neurons is the concentration at which you can identify an odor (air, water and fat). • The odour activity value is the concentration divided by the threshold.

This is the "odor threshold." In the per-formance of the tests the odorant may in some cases be dissolved in a neutral liquid such as water. Odor thresholds for some materials may be as low as 1 ppm (by volume) or even less. is cockermouth in allerdaleWebthreshold 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).
