I really want to see elimination of lead (projectiles, lead styphnate primers, etc.) in firearms next.

When I go to the range, every once in a while, I'll see one of the older marksmen who's there with his squirrel hunting rifle, chambered in .22 LR. I've noticed that he seems to have a tremor in his hands when he's loading his magazines. Essential tremor is linked to lead exposure [0]

Most .22 LR projectiles are either just lead or have a copper "wash" over the lead, not a proper jacket like you see on other rounds.

I wonder, if you shoot those loads for long enough, and breathe in enough gunsmoke, do you get that problem?

As for the proof being in our hair... well, not mine. Chrome dome over here XD

Why would lead be in the gunsmoke? Everything leaded should be coming out the business end of the firearm, and it should be coming out with some gusto.

Are you proposing that the base of the bullet which is exposed to the burning propellant magically remains at room temperature, and none of the lead in the base of the bullet is vaporized? What about the process of forcing the projectile into the barrel's spiral grooves at very high speed, leaving grooves in the side of the bullet. Where do you suppose that displaced and/or vaporized material ends up? What about the lead styphante that is combusted in the primer? I am not aware of any firearm that has a muzzle filter that removes primer residue from the combusted gunsmoke.

I am directly questioning whether the .22LR bullet creates more lead vapor than any other round as per OP statement.

I haven't measured this but all the ingredients are there: they're unjacketed or copper washed, and they are made from soft lead rather than a hard-cast alloy. You can get a polymer-coated or pure copper round but that's pretty unusual since it goes against the cheap plinking purpose most people are using the .22 for.
