The study on loons was over a 15 year period and they found that 7 loons died from lead ingestion. That # isnt even statistically signfifcant. For people that bluegill fish that may not affect you. I lost over 100 jig and pigs last year fishing all over the state. I probably have $2000 in lures that have lead in them. Upgrading to tungston would cost me thousands of dollars.
