I'm going to go only from compounds I've handled personally, largely quite benign. So... Hydrogen sulfide? More toxic than HCN and doesn't smell half as pleasant. Or thionyl chloride: not sure how nasty it actually is but its vapours turned my needles and seals black so I'll avoid that one, ta.

Haha, I came across this old post searching for thionyl chloride related threads lol- but for my two cents worth:

I would determine a substance to be in the top 'nastiest' if it still poses significant life threatening or incapacitating risks after approriate safety measures have been implimented. Things like dimethyl mercury which can readily and rapidly penetrate through most safety gloves (latex, PVC and I think nitrile- but slower).

Things like concentrated nitric acid aren't likely to kill you unless you do something terribly stupid with it (like throwing it into the air above you).

Gases would still probably be significant candidates though- although not so much if you work in a decent fume hood.

there`s 1000`s really, but common ones...

2. hexavalent Chrome
3. Beryllium (dust)
4. DMSO
5. Psychotropic drugs
6. metaloids and Selenium.
7. Hydrazine
8. Dishonest Poisons
9. unpredictable explosives
10. Acetaldehyde (think Hangovers)

in no particular order.

I should add any five membered rings with more than three nitrogen hetereoatoms in them to the nasty list.

You've come a long way. Remember back when we defined what a velocity meant? Now we are talking about an antisymmetric tensor of second rank in four dimensions.
