One of the most insidious toxins in our environment is mercury. Mercury is a pervasive toxin that is a staggering environmental problem. It is in our water, food, & air. Without a clear understanding about these routes of exposure and the potential hazard it poses to one’s health, many individuals easily accumulate a mercury body burden over time. Mercury is extremely toxic to brain tissue, and could be a significant risk factor for Alzheimer’s disease (AD) in some individuals.
