  • Title: Effect of metal chelators on excretion and tissue levels of essential trace elements.
    Author: Tandon SK, Jain VK, Mathur AK.
    Journal: Environ Res; 1984 Oct; 35(1):237-45. PubMed ID: 6436015.
    Abstract:
    The influence of one, three, and six doses of ethylenediaminetetraacetic acid (EDTA), diethylenetriaminepentaacetic acid (DTPA), and triethylenetetramine (TETA) on the urinary excretion of Ca, Cu, Fe, and Zn, and on their levels in liver, kidneys, heart, and serum in rats, was investigated to ascertain their suitability in amelioration of metal intoxication. While excretion of all the essential trace metals examined was enhanced significantly, the tissue and serum levels of some of them either increased or decreased after administration of the chelators. The results suggest depletion of some of the endogenous trace metals from the body and their intertissue redistribution following treatment with these chelating agents.
