It is aslo found in American tap water!!(Wolfe, 2010)









Treatments

If chromium 6 is found in water iron sulphate can be added to revert it to chromium 3 which is actually a nutrient which humans need.(Dubar, 2010)





There is no proven cure for chromium toxicity. For treatment the person will just have to stop the exposure and let the chromium 6 work its way out of the body naturally. There should be precautions of using protective gear and equipment when you know your are working around chromium 6.(Dogra, 2010)


Opinion

I believe that chromium 6 should not be allowed in the production of the many products and especially not be allowed in tap water. I think this because of all the harmful effects which include multiple types of cancer. The cancers and many of the other dangers are without a cure meaning that you have no sure hope when you are confronted with toxicity.





Chromium 6 contains only 22 neutrons in the Nucleus!

Below is a video about chromium 6 and Erin Brockovich, she is a lawyer who is famous for covering Chromium 6 and other envirnmental cases.

  6. Your blog is really informative and it is scary how high the amounts of chromium 6 are in some of the US cities. Is chromium 6 found in canadian tap water, or do we have limits on the amount that can be in the water?
