However, the lanthanide ion is capable of altering the metal‐binding state of E. coli DNA polymerase from two metal ions to one, raising doubt as to the validity of the proposed one‐metal–ion alysis for EF (Brautigam et al, 1999).

EDTA is a synthetic amino acid that has proven to be the best broad-based heavy metal chelator with very few adverse effects. The half-life of EDTA in the body, via the rectal route of administration, can be up to eight hours, and is excreted through feces and urine within 24 hours; almost none of the Kelate4Life EDTA is metabolized.
Despite the potential for metal detector finds, nearly no reports exist of metal detectors being used on Bolivian archaeological and historic sites. In this piece, I will offer some reasons of why I think that illicit metal detecting is not a significant problem in Bolivia, followed by a discussion of the type of looting of metal heritage objects that the region does experience.

Calcium is a silvery white metal which is obtained by the electrolysis of molten calcium chloride. It is one of the most abundant metal elements on Earth (41000 ppm), but it never occurs as the pure element, the main deposits being limestone (CaCO 3 ), Dolomite (CaCO 3 .MgCO 3 ) and Gypsum (CaSO 4 .2H 2 O).
