Question

The compound used in the treatment of lead poisoning is :

• A. $EDTA$
• B. Cis-platin
• C. D-penicillamine
• D. desferrioxime $B$

Answer 1

The Correct Option is A

Lead poisoning is a medical condition caused by elevated levels of the heavy metal lead in the body. It can cause a range of neurological issues and other severe health problems. To mitigate lead poisoning, chelating agents are used. A chelating agent binds metal ions, facilitating their excretion from the body.

The compound $EDTA$ (Ethylenediaminetetraacetic acid) is a well-known chelating agent. It works by forming a stable, water-soluble complex with lead (and other heavy metals), which can be excreted by the kidneys. This makes $EDTA$ an effective treatment for lead poisoning. The correct use of $EDTA$ in such detoxification processes is well-documented.

Let's examine the options and rule out the incorrect ones:

• Cis-platin: This is an anti-cancer medication primarily used in chemotherapy. It is not suitable for treating lead poisoning.
• D-penicillamine: Though it is a chelating agent, it is mainly used for copper, as in Wilson's disease treatment. It's not the first choice for lead poisoning.
• Desferrioxime B: This compound is used as an iron chelator in conditions like hemosiderosis. It doesn't chelate lead effectively.
• $EDTA$: As explained, $EDTA$ is the most suitable and effective option for treating lead poisoning.

Therefore, the correct answer is $EDTA$.
