ICP/MS elemental analysis of hair taken from TSA n°1, a naturally mummified South-American specimen and a contemporaneous sample.

Note the enormous levels of lead, mercury, zinc and arsenic in our study specimen compared to the naturally mummified and contemporaneous specimens. Calcium, potassium, magnesium and sodium are, by contrast, much increased in the hair of the naturally mummified specimen.
Values are expressed in mcg/g of hair; NA = not applicable.
