The spray can also cause irritation and even temporary blindness, and is sufficiently powerful to be detected by a human nose up to 5.6 km (3.5 miles) downwind. [20] Their chemical defense is effective, as illustrated by this extract from Charles Darwin's 1839 book The Voyage of the Beagle:
Among mammals, skunks can eject a noxious fluid from their anal glands. It is not only foul smelling, but can cause skin irritation and, if it gets in the eyes, temporary blindness. When it feels threatened a camel will bring up their stomach contents, along with saliva, and project it out towards the threat to distract, surprise, or bother the ...
Anosmia, also known as smell blindness, is the loss of the ability to detect one or more smells. [ 1 ] [ 2 ] Anosmia may be temporary or permanent. [ 3 ] It differs from hyposmia , which is a decreased sensitivity to some or all smells.

Skunks are most active in spring. They’re most known for their ability to spray musk when threatened – they can spray with accuracy up to 15 feet
Butane-1-thiol, also known as butyl mercaptan, is a volatile, clear to yellowish liquid with a fetid (extremely foul-smelling) odor, commonly described as "skunk" odor.In fact, 1-butanethiol is structurally similar to several major constituents of a skunk's defensive spray but is not actually present in the spray.

However, new research suggests a link between weight loss drugs and blindness (and other eye issues), leading some to refer to the issue as “Ozempic blindness.”
Since odor detection may be an indicator that exposure to certain chemicals is occurring, olfactory fatigue can also reduce one's awareness about chemical hazard exposure. Olfactory fatigue is an example of neural adaptation. The body becomes desensitized to stimuli to prevent the overloading of the nervous system, thus allowing it to respond ...
