I'm sorry I don't know the answer to your question.

I did want to suggest that you be sure the amalgams are being removed by a dentist that take all of the proper safety precautions. I know of some people who have become sick after having amalgams removed by dentists that did not take safety precautions.

I had mine removed in July of 2000 and had a dramatic recovery. If you're interested, here's my story:

Best of luck in your removal.
