WebOdor threshold value (OTV) (also aroma threshold value (ATV), Flavor threshold) is defined as the most minimal concentration of a substance that can be detected by a human nose. Some substances can be detected when their concentration is only few milligrams per 1000 tonnes, which is less than a drop in an Olympic swimming pool.
Chloromethane was first synthesized by the French chemists Jean-Baptiste Dumas and Eugene Peligot in 1835 by boiling a mixture of methanol, sulfuric acid, and sodium chloride. This method is the forerunner for that used today but uses hydrogen chloride instead of sulfuric acid and sodium chloride. Chloromethane is produced commercially by treating methanol with hydrochloric acid or hydroge… Web3.12 Odor Threshold: 205-307 ppm 3.13 IDLH Value: 2,300 ppm 3.14 OSHA PEL-TWA: 25 ppm 3.15 OSHA PEL-STEL: Not listed. 3.16 OSHA PEL-Ceiling: 125 ppm 3.17 EPA …
• 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.
WebChlorine gas is primarily a respiratory irritant. At low concentrations, chlorine gas has an odor similar to household bleach. As the concentrations increase from the level of detection by smell, so do the symptoms in the exposed individual.
