The compound used in the treatment of lead poisoning is:

(A)EDTA✓ Correct
(B)Cis-platin
(C)D-penicillamine
(D)desferrioxime B

Answer: (A)

Solution

Lead poisoning is treated by chelation, and EDTA is the classic chelating agent: it wraps around the

Pb X^{2 +}

ion to form a stable, water-soluble complex that the body can excrete. Cis-platin is an anticancer drug, D-penicillamine is used for copper and mercury, and desferrioxamine B for iron overload, so the agent for lead is EDTA.
