How does EDTA help as a cure for lead poisoning?
We employ a ligand that can create metal complexes with lead to eliminate lead from our bodies. EDTA is a chemical that is used to treat lead poisoning. Ethylene diamine tetraacetic acid (EDTA) is an acronym for ethylene diamine tetraacetic acid. It has two nitrogen atoms and four oxygen atoms, all of which are capable of donating electrons to metals. Lead replaces calcium in the Ca–EDTA complex in the body. Lead-EDTA, a more soluble complex, is excreted in urine.
