is a polyamino carboxylic acid and a colourless, water-soluble
solid. Its conjugate base is named ethylenediaminetetraacetate.
It is widely used to dissolve limescale. Its usefulness arises
because of its role as a hexadentate ("six-toothed")
ligand and chelating agent, i.e. its ability to "sequester"

is produced as several salts, notably disodium EDTA and calcium
disodium EDTA." http://en.wikipedia.org/wiki/EDTA

It is possible that renal dysfunction from lead nephropathy is
reversed by minimizing lead exposure and chelation therapy. Lead
nephropathy should be included in the differenitial diagnosis
of causes of chronic kidney disease and occupational and environmental
lead exposure should be investigated carefully during the medical
