Lead is serious stuff, I worked for an abatement company for quite a while and blood testing was regular thing for us.
We still have die offs from lead shot in swans here in the Skagit Valley. Being large white birds they are very easy to spot when they die.
Are you telling us that all of these dead large white swans were autopsied and all died from lead poisoning? And all of this lead poisoning could be traced to the swans ingesting lead shot from the past?
Are you telling us that if we could somehow remove all traces of lead shot that had been fired in the past in Skagit Valley, that your swans would live forever? Or is it possible that these large, easy to spot, dead white swans died from old age, natural causes, disease, crippling after being shot with Inferior Shot (thanks Ted), etc.?
We know lead is serious stuff. We know it can be toxic. And we also know how stable it is in the solid masses of spend shot and bullets as compared with the lead dust from old paint, leaded gasoline, and dust producing manufacturing processes such as the dust produced by lead acid battery companies. The lead ammunition bans are nothing more than a ploy to increase the cost of ammunition. We have read and easily refuted the reams of junk science that the anti-lead ammunition guru Ben Deeble, aka GrouseGuy, used to post here.
