Somehow I just don't believe that the amount of lead that scuba divers introduce to the marine environment from uncoated weight is any more than the amounts left behind by sport fishermen.
Slightly off topic, but with all the concern over lead, and lead dust, does anybody else remember the split-shot fishing weights that we all used to crimp onto the line with out TEETH!
Somehow in retrospect I think that wasn't so healthy....
Nwbrewer,
I think that you are absolutely correct.
I am sure that fishing, old lead varnishes and paints on ships, and even runoff from residential paint removal EACH deposit more lead in water than diving ever will. I just think that we should each do our part. This would seem to be especially true for a sport that revolves around aquatic life.

I made weights too, I stole some big blocks of granite
Those sound really cool. How would you cut the slots for the belt? Can you post some pictures?
