treatment of lead poisoning in adults

Hello,

I am looking for information on the treatment of lead poisoning in adults. Could you please point me to relevant links?

I am wanting to know things like:
*To what extent is chelation therapy considered an 'alternative' treatment?
*Why is it that 'conventional' GPs have never looked for lead poisoning - and that it took an 'integrative' GP to find it?
*Is chelation therapy considered 'conventional' at certain levels (eg for heavy cases of poisoning) but not for less heavy cases?
*Are there options other than chelation therapy?
*What are the different ways of receiving chelation therapy - eg at a GP? in hospital? At some kind of toxicologist?
*What are the costs involved in chelation therapy?

PS. Has anyone listened to the podcast here http://probioticforums.com/blog1.php/clinical-rounds-connection-between-heavy
?

It is about Connection Between Heavy Metals, Chronic Infections and Psychological Trauma
