Posted By: JSHarristhe allowable exposure limits are quite high (around 100 µg/m³ in air in a workplace, which is a fair bit in volume of mercury vapour terms)

They say that anyone with mercury fillings has a mercury vapour level in their airways that's three times as high as the workplace limit.

I had a 2.5yr bout of severe depression that cleared completely within 6wks of having the last of my mercury fillings out, combined with kinesiologically-guided homeopathic treatment for organ support in eliminating in-body residues (which don't clear unless so aided - well, 50yr half-life).

Mercury badly affects brain/nervous system in 15% of people, but most can have it controlled by annual homeopathics. But ignored by most of the population, mercury perpetually overloads and prematurely exhausts the immune system.

You need to adopt the lazy gardener approach which I have perfected. Basic principle is plant, and harvest or plant transplant and harvest.
