That is a hard question to answer because at last count there were over 400 involved as well as combinations of those created during combustion. Mercury,pbc, pvc, dioxin, lead, the list goes on, as well as numerous respiratory infections caused by microscopic glass silica and puverized conrete, which of course could also set off an autoimmune reaction . Im sorry i cant be of more help, im looking for the complete list myself. If i get it ill send it to you. I had a massive exposure then a continuing exposure for 4 months.
