So,the lead matters and the mercury does not.
Of course mercury matters. But to compare the 4 milligrams of mercury in a CFL, which is sealed away from the environment, with the roughly 3,000 tons a year of lead that's released into the environment via hunting rounds, and to claim that one invalidates the other, is ridiculous. And it smacks of an attitude of "everything's just fine, leave it alone," even when it's not necessarily fine.
That lake where you can't eat the fish is that way because decades ago when science was trying to convince people that coal-fired power plants were dangerous and dirty, most folks had the attitude that we'd been using coal for power for a hundred years, therefore it was obviously safe. And anyone saying otherwise was some kind of pinko commie tree hugger. Now you have a lake where you can only eat one fish a month. I for one would prefer not to have my future kids sitting where I am in twenty years, wishing that people had listened about the dangers of lead before we filled the ecosystem with it. Because you can't put the genie back in the bottle.
There's another good article here that goes into details about the lead levels in the blood of various people tested in North Dakota, including one older hunter who was within 0.2 milligrams of the legal definition of lead poisoning.

You could handle the problem by using non lead ammo for yourself,but you prefer to ban lead.
Actually, I prefer to not irrationally decry scientific research claiming it's a conspiracy to seize guns. You can cast whatever you like to plink with. And there's plenty of lead-free .22 rimfire rounds available too, for about the same price as I'd pay for the same sized box of lead based .22s. There's lots and lots of lead-free hunting rounds, and there's even alternatives for people who like to cast, like tin, which is slightly lighter but also much easier to melt. So to equate lead-free hunting bullets for hunting with an assault on hunters, or part of some scheme to take away guns, is silly. You might as well be demanding the "liberty" to drench yourself in DDT. Buy one box of lead-free bullets a year to hunt with and move on with life.
