Lead Linked to Aging in Older Brains

Once we absorb things like Lead, Mercury, Dioxins, Pesticides etc, they cannot be easily eliminated from the system, and can accumulate. Go and have a blood test looking for heavy metals, and toxic substances like dioxins, you may be shocked. Dioxins are in things like DDT (pesticide) Agent Orange (herbicide) Once they are in the environment they permeate the environment. They can be banned, but they will never go away - Some of them are refined Elements. That also includes depleted Uranium, and of course Chronic Lead poisoning (Gunshot Wounds)

clipped from www.mail.com MALCOLM RITTER Could it be that the "natural" mental decline that afflicts many older people is related to how much lead they absorbed decades before? The new work suggests long-ago lead exposure can make an aging person's brain work as if it's five years older than it really is. If that's verified by more research, it means that sharp cuts in environmental lead levels more than 20 years ago didn't stop its widespread effects. "We're trying to offer a caution that a portion of what has been called normal aging might in fact be due to ubiquitous environmental exposures like lead," says Dr. Brian Schwartz of Johns Hopkins University The fact that it's happening with lead is the first proof of principle that it's possible Other pollutants like mercury and pesticides may do the same thing, In fact, some recent research does suggest that being exposed to pesticides raises the risk of getting Parkinson's disease a decade or more later. Experts say such studies in mercury are lacking.
