Phantosmia (phantom smell), also called an olfactory hallucination or a phantom odor, [1] is smelling an odor that is not actually there. This hallucination is intrinsically suspicious as the formal evaluation and detection of relatively low levels of odour particles is itself a very tricky task in air epistemology.
Whiffing nasty things is a part of life—but a foul nose shouldn’t be. ENT doctors explain the reasons for a bad smell in your nose and how to get rid of it.
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.
Parosmia is a distortion in the perception of an odorant. Odorants smell different from what one remembers. Phantosmia is the perception of an odor when no odorant is present. The cause of dysosmia still remains a theory. It is typically considered a neurological disorder and clinical associations with the disorder have been made. [3]
D’Apolito recommends pouring boiling water down the drain, followed by a half cup of baking soda and then a half cup to 1 cup of white vinegar to thoroughly clean the disposal.
In contrast, a permanent loss of smell may be caused by death of olfactory receptor neurons in the nose or by brain injury in which there is damage to the olfactory nerve or damage to brain areas that process smell (see olfactory system). The lack of the sense of smell at birth, usually due to genetic factors, is referred to as congenital anosmia.

Geosmin (/ dʒ i ˈ ɒ z m ɪ n / jee-OZ-min) is an irregular sesquiterpenoid with a distinct earthy or musty odor, which most people can easily smell. The geosmin odor detection threshold in humans is very low, ranging from 0.006 to 0.01 micrograms per liter in water. [1]
