**Question:** TRUE about Aluminium phosphide poisoning is all, EXCEPT:

A. Aluminium phosphide is a phosphine-releasing compound used for agricultural purposes.
B. The primary target organs in Aluminium phosphide poisoning are the liver and kidneys.
C. The clinical presentation of Aluminium phosphide poisoning is similar to carbon monoxide poisoning.
D. The treatment involves supportive care only.

**Correct Answer:** C. The clinical presentation of Aluminium phosphide poisoning is similar to carbon monoxide poisoning.

**Core Concept:**
Aluminium phosphide (AP) is a phosphine-releasing compound commonly used as a fumigant pesticide for grain storage. When AP is ingested, it reacts with water and gastric acid to produce phosphine gas, which is highly toxic. Aluminium phosphide poisoning primarily affects the liver and kidneys, leading to organ dysfunction. The similarity to carbon monoxide poisoning is a common misconception, which is why option C is incorrect.

**Why the Correct Answer is Right:**
In Aluminium phosphide poisoning, phosphine gas leads to the inhibition of cytochrome c oxidase, a key enzyme in the respiratory chain of cells in the mitochondria. This results in cellular dysfunction and organ failure. The primary target organs in Aluminium phosphide poisoning are the liver and kidneys, which are responsible for detoxifying the phosphine. This explains why options A, B, and D are true statements.

**Why Each Wrong Option is Incorrect:**

**A.** Aluminium phosphide is a phosphine-releasing compound used for agricultural purposes: Although AP is used as a pesticide, the focus of the question is on its toxic effects, not its agricultural purpose.

**B.** The primary target organs in Aluminium phosphide poisoning are the liver and kidneys: As explained earlier, the primary target organs are indeed the liver and kidneys.

**D.** The treatment involves supportive care only: While supportive care is essential, additional interventions like administering activated charcoal, gastric lavage, or administering hyperbaric oxygen therapy might be needed, depending on the severity of the case.

**Clinical Pearl:**

In Aluminium phosphide poisoning, it is crucial to promptly recognize the symptoms and initiate appropriate management. Symptoms include nausea, vomiting, abdominal pain, diarrhoea, respiratory distress, seizures, and even cardiopulmonary arrest. Prompt intervention is necessary to prevent complications and improve patient outcomes.
