On the topic of scents, I used to be able to smell methanol when I first started using. It had a distinctive smell. But now when I opened the
bottle...No smell? Even when I pour a bit into a shallow dish and ignore the correct method for smelling chemicals, there is no smell. Need less to
say I only smelled, or rather attempted to smell it, like that once.

I don't know of any methanol desensitization. I remember hearing that those methyl esters in sinus spray will ruin your sense of smell (you know,
the gear you stuff up your nose and pump).
Come to think of it, who else likes the smell of blood? I have always enjoyed the scent - even my own blood noses smelled fragrant and pleasant. My
work at an abattoir didn't dispel my love of the scent (in fact, after a dingoes breakfast and no lunch break, at the end of a 12 hour shift -
those carcasses look miiiiighty appetizing!).
Anyone else?

To me methanol has about as much of a smell as water does, I was dumbfounded the first time I tried to smell it- I had always heard of at least some
odor ascribed to it.
A specific inability to smell just this one chem as was suggested? I doubt it, it's probably a consequence of a lifetime of inhaling shit. The
odor of methanol is already known to be faint, chemical exposures probably eliminated what little sensory ability for this substance we are born with.

Hmm, after using HCl a lot in one day, I could not smell it at all. It still stung the nose, but smelled like plain air. It could have been that my
nose was clogged, but I doubt it.
Now I can smell HCl easily. Good.
Edit- does eating Gahhlic damage the nose? My friend has a very poor sense of smell, he blames it on garlic, and says his ability to smell varies
inversely with the amount of garlic eaten. This is slightly OT I know...

Everyone knows that the "correct method" of smelling chemicals is for sissys. You should always place your nose in the container and inhale
deeply. For better effect, warm the substance in question to just below its boiling point. I do it all the time... *falls down dead*.

I have noticed that methanol has a fruityish smell to it. This has been routine when buying the 99.9% pure hardware store methanol. I like the smell
and would drink it if I hated myself.

Yes, that was the same smell and source of methanol that I had. But now I can no longer smell that fruity smell.

I can still smell methanol, but I haven't used it very much.
Has anyone else lost the ability to smell HCl for a while?

I can't smell ammonia anymore. My sense of smell is otherwise very good. A couple of intense exposures to the gas has left me unable to detect
it, unless my eyes start to water or it irritates my throat. Has anyone else had this happen?

What's the vapour pressure of iron at normal temperatures?
More seriously, I'm sure we are all familliar with the smell of copper ie the smell you get on your hands after handling copper coins and that
sort of thing. Does anyone have any ideas what the (volatile) compound(s) is that gives this smell?

Isn't it the copper reacting or altering the shape or proteins on the skin surface?
Or something like that .....

I always thought that the smell was H2S, IIRC there is always some copper sulfide on copper, which reacts with acids on the skin to make H2S. That is
why old copper smells much more than new copper. I love this smell in small amounts.

WEll, ever tasted a bit of copper sulphate solution? It tastes/smells exactly like copper pennies, or pipes.
Hence I think our nose has some receptors for divalent metal ions, of specific types. Iron can be detected too. But not lead, not Ca, I dont know
about any others.
H2S? Nah, the smell of that is distinctly different. Also did you notice that this coppery taste/smell resembles slightly SO2? I wonder whether
that's a coincidence.

Ah, the wonderful realm of tastes and smells...
I have desired many a time to taste some copper sulfate, and other chemicals, but have never worked up enough courage/foolishness to taste known
toxins/carcinogens/etc. puposely. I'm not saying you are being foolish, I just do not know enough about toxins, chemicals, and their effect on
my body to feel safe tasting some of them yet.
I still think it's very very small amounts H2S, but concentrated H2S does smell different indeed.
Would anyone else describe this penny smell as teeth-numbing? I can feel the smell in my teeth sometimes. Also, iron makes the teeth feel good...

Speaking of tasting stuff, I just tasted H2SO4 today. It was a really dilute solution that was CLEAN and that I made from MgSO4, not drain cleaner
crap.
It tastes bad. Very sour in a strange way, and bitter at the same time.

I dont know, but I do know that it's used to give gas (butane,propane etc.) a (disgusting) smell so you can detect leaks (so you dont
suffocate/blow up your house )

Poop,solid waste, is a complex mixture of substances based on your diet. Usually it would be undigested proteins, cellulose, starches etc. The odor
is caused from Skatole. This is a cyclic nitrogen compund related to indole. Look both of them up. Many proteins have sulfur and Hydrogen sulfide is
present in farts too.

my taste in chemical smells
My favorite smells are:
2-hydroxy-5-methoxybenzaldehyde
p-ethoxyphenol (reminds me of pistachio icecream, and it tends to linger too)
1-octanol
1-nitropropane
Absolutely horrible are:
1. pyridine ! (this sickening smell stays in my nose for hours without getting used to it)
chloroacetyl chloride
butyric acid of course ;-) (the anhydride actually smells much better by the way)
and... hot hexane, at first the fumes smell agreeable and a bit fruity, but they also stay in the nose and become sickening.
As a reply to vulture, concerning the bad smell of blue methylated spirits. I once used this as is in a dissolving metal reduction. When finished the
smell was everywhere, in my clothes, in my hair, it surrounded me like a cloud and I became very nauseous. 
I want to bet on it that there is pyridine or a derivative in there.

I just got a really good whiff of conc. NH3 gas. (By accident)
Add it to my list of favorite smells. 
I know it's got to be bad for humans, but it smells/feels kind of like a listerine strip mixed with oil of wintergreen. Dilute ammonia is just
annoying.

Cyrus, you ARE joking, right?
NH3 blows me off my ass.
And someone mentioned that they no longer are able to smell HCl - yeeeeeeeeah yeah. I find it hard to believe something as potent as HCl is
undetectable by le nez.
