Remove lead from the environment?... Where do they think it comes from? Lead ore from places like the sweetwater mine is 98% pure.

Concerns about it dissolving? Lead pipes from the Roman days are still in service in Italy

So maybe the problem is that it could be ingested by wildlife? I can see that with bird shot, maybe split shot in some locations, but a 3 oz bank sinker isn't likely to be thrown any place a duck can go. The only fish that I've heard of ingesting lead were in BASS tournaments, and I think they had help.

When I shoot I send and ounce of lead into the wild, fly fishing that would last nearly a year for me. This is just junk science without real thought about how the world really is.
