Which of the following is used for the treatment of lead poisoning?

Options

A. Oxalate ion
B. OMG
C. Glycinate ion
D. EDTA

Answer

To solve the question of which compound is used for the treatment of lead poisoning, we will analyze the options provided and identify the correct answer step by step.

### Step 1: Understand the Problem
The question asks for a treatment for lead poisoning. Lead poisoning is a serious condition that requires specific chelating agents to remove lead from the body.

### Step 2: Review the Options
The options given are:
- A) Oxalate ion
- B) DMG (Dimethylglyoxime)
- C) Glycinate ion
- D) EDTA (Ethylenediaminetetraacetic acid)

### Step 3: Analyze Each Option
1. **Oxalate Ion**: This is a bidentate ligand, but it is not commonly used for treating lead poisoning.

2. **DMG (Dimethylglyoxime)**: While DMG can form complexes with nickel and palladium, it is not primarily used for lead poisoning.

3. **Glycinate Ion**: Glycinate can act as a ligand but is not specifically used for lead poisoning treatment.

4. **EDTA (Ethylenediaminetetraacetic acid)**: EDTA is a well-known chelating agent that effectively binds to heavy metals, including lead, and facilitates their excretion from the body.

### Step 4: Identify the Correct Answer
Based on the analysis, the compound that is specifically used for the treatment of lead poisoning is **EDTA**. Therefore, the correct answer is option **D**.

### Final Answer
**D) EDTA (Ethylenediaminetetraacetic acid)** is used for the treatment of lead poisoning.
