Since only 4 million tons of lead are mined in the world per year, the US is saying 1 % of all lead mined in the world is lost in sinkers in the US. Bull. The only meaningful number would be the lead level in the fish in non-industrial areas. And I bet almost no lead in all fish comes from sinkers. And even less would come from flyfishers. (less than zero???). Oh well.
