I had a Hair mineral analysis done (USA lab) which showed out the roof levels of Vanadium and Cobalt. Both of these are used extensively in aviation fuel.

Incidentally while checking cobalt, I found many sites linking hip implants with Cobalt poisoning. (I don't have any implants) Caused when the joints rub and shave off bits of the metal. Not all the metals used in hips contain cobalt but for those with bad cobalt poisoning they are advised to get a new replacement without cobalt in it.

I am now on a major natural handling detox programe to handle the toxics in my body from the aviation fuel. I have a list of those if anyone is interested. I have also stopped the ful vapour entering my home (have to keep everything shut for now!) and have an Innovair air purifier running constantly.
