LEAD POISIONING AND FLINT, MICHIGAN, WATER

I hear a lot of hysteria about lead in Flint.  They say things like "You can't shower in bottled water."  Well, lead is not a skin poison* so showering or baths should be no problem unless you drink the shower or bath water.  When I was a child, we were told not to drink water from the hot water tap because it might contain lead.  Apparently a lot of the plumbing in Flint is very old and probably needs to be replaced anyway.  Modern plumbing uses PVC pipe and other plastic tubing in the homes.

Lead in blood does not have a long half life so just switching to bottled water should rapidly deplete lead in the blood.  For a more permanent basis, lead and iron removing filters work well although not all filters remove lead so you need to check.

If that is not fast enough, then there is chelation therapy that works well using agents like EDTA.**  Curiously EDTA at least used to be found in commercial salad dressing to preserve flavor.  This strips all the heavy metals from your body, including essential ones.  It may also be found in shampoos, body washes, deodorant and skin creams.***

The two main repositories of lead in the body are bones and kidneys.  Bone is the major repository so children growing bone can take on a large lead burden that then leaks out later in life.  A colleague of mine came from South Africa, and he found the lead in his blood had the isotopic composition of South African lead that is very distinctive. The effects of lead on the brain are above my pay grade and I refer you elsewhere.****

I heard on the Rachel Maddow show (where the Flint, Michigan, water-lead problem was brought to public attention), that a large part of the Flint water system has water standing in pipes averaging only about a day whereas in another large part it stands for an average of six days and is the area with the highest blood lead levels.  She recently held a Town Hall in Flint (http://www.detroitnews.com/story/news/michigan/flint-water-crisis/2016/01/27/rachel-maddow-flint/79424440/)  In addition to lead poisoning, it is now suspected of causing legionnaires disease.
Calcium Disodium EDTA
Ethylenediaminetetraacetic acid, or simply known as EDTA, is a preservative found in many foods including sodas, sandwich spreads and sauces. EDTA is also found in many cosmetic products including shampoos, body wash, deodorant and skin creams. EDTA may cause allergic reactions, asthma attacks, skin rash and possible kidney damage. Studies have also found that sustained intakes of calcium disodium EDTA can lead to essential mineral depletion in dogs. - See more at: http://naturallysavvy.com/eat/harmful-food-additives-in-salad-dressing#sthash.1BO09aeT.dpuf
