This one is specifically about chelation. It does a great job of dismantling the claims in three important ways.
1) that children with autism probably don't have higher mercury levels than children without autism and that tests that show this are fraudulent
2) there is no reason why chelation would work in the first place
3) there is no evidence that children improve after chelation and there is some evidence that chelation may be harmful.
