Odor can be measured with the help of field olfactometer in terms of OU/m3. But the toxicity level or the presence of pollutants has nothing to do with the odor in most of the cases, except the gaseous pollutants with an obnoxious smell and vice versa. Despite the real fact, as per human psychology, we presume if there is an odor there must be toxication of the ambient air which is completely illogical. Please share your views on it and what's the local believe in your area/ country. Also, inform others about it to avoid the myth.
معلومة جيدة. فعلا في محيطي نعتقد أن هناك ارتباطا بين تلوث الهواء ورائحته شكرا لك على المعلومة القيمة
good information. Actually in the ocean we believe there is a link between air pollution and smell thank you for the valuable information
There is a direct correlation between odors that appear in the atmosphere and the presence of volatile substances and air pollution and cause the emergence of these smells, and this applies to most air pollutants, but a few of them that can contaminate the atmosphere without smell.
There is no question that a correlation would exist between contamination level and odor. However in minute quantities it can be tricky. For certain compounds one can smell even at low levels of concentration that may not be harmful to humans. On the other hand certain other compounds have a higher threshold for detection by smell and the concentration at that point may turn out to be harmful. For example take natural gas which has no odor. On purpose a small amount of hydrogen sulfide (H2S) is added so that humans can smell it even at very low concentrations alerting the presence of natural gas that is present with it and preventing a possible accident.
Yes, there is a relationship between odors that appear in the atmosphere and the presence of volatile substances and the air pollution .
