Ingestible lead is the issue. If our waters were acid enough to make water lead-toxic (by causing lead to oxidize, or basic enough to make lead dissolve or otherwise leach), there wouldn't be any fish or wildlife to protect already.
We have a law banning lead split shot and other sinkers of certain sizes in Vermont- lead in small sizes like birdshot for waterfowling and split shot for sinkers is the big issue.

"
As of January 1, 2007, it will be illegal to use a lead sinker weighing one-half ounce or less to fish in Vermont."
Lead in "carcasses?!" That's way too much of a stretch for me to intellectually accept.
"
Lead is banned in gasoline, children?s toys, and paint because of its effects on human health. In the United States, there is an accelerating trend to expand efforts to reduce lead contamination associated with firearms and hunting. California and Arizona have recently implemented mandatory and voluntary bans, respectively, on lead ammunition to facilitate California condor recovery."
"
gasoline, children?s toys, and paint"
because it is ingestible- paint dust, burned gasoline by-products put lead into water runoff and road side dirt, lead additives leach from plastics put in children's mouths.
Our wildlife is more threatened by the improper use of a pen by not-always-correct cause-motivated PACs than by lead ammo. I can see the argument re: lead bird shot, but the science has to support legislation, not opinions.
Rifle ammo: banning lead projectiles for hunting has not been scientifically studied sufficiently to conclude that lead ammo is an issue. With all the R&D on making projectiles that are not frangible and the decline in hunting overall, what we do today has very little impact compared to the volume of ammo (lead) expended in the 1800s and 1st half of the 1900s. I personally use Barnes X Bullets which are solid copper, so I am not anti-anything. But the lead ammo ban discussions I have heard are more politically motivated than anything. I want to know what the science says, not just a few studies and opinions.
However this is a fishing forum; banning lead in fishing lures is not the worst thing that could happen. With open-mindedness, I support the lead sinker ban. I am a sportsman- I get it.
Sorry for the rant; I feel better now.
