What percentage of chronic(incurable) illness in our society is caused by mercury?

Buttar the chelation doctor believes it's about 30%. I remember Russ said something like 20-40%.

There are anti-mercury docs who believe most autoimmune disease is caused by dental amalgam. Interestingly also gold or other metal fillings can cause autoimmune disease.
A lot of chronic illness seems to be autoimmune diseases even things such as depression have been linked to autoimmunity.

What chronic illness is not caused by mercury poisoning/autoimmunity in your opinion?
