Question

Accumulation of iron particles in tissues lead to

• A. Asbestosis
• B. Silicosis
• C. Siderosis
• D. Black lung disease

Hint:

Iron dust $\rightarrow$ Siderosis Silica dust $\rightarrow$ Silicosis Asbestos fibres $\rightarrow$ Asbestosis Coal dust $\rightarrow$ Black lung disease

Answer 1

The Correct Option is C

Concept:
Occupational lung diseases occur due to inhalation of different dust particles. Different particles produce different diseases. 

Step 1: Recall major occupational diseases. \[ \begin{array}{|c|c|} \hline \text{Particle} & \text{Disease} \\ \hline \text{Silica dust} & \text{Silicosis} \\ \hline \text{Asbestos fibres} & \text{Asbestosis} \\ \hline \text{Coal dust} & \text{Black lung disease} \\ \hline \text{Iron dust} & \text{Siderosis} \\ \hline \end{array} \] 

Step 2: Apply the information.
The question specifically mentions accumulation of iron particles.
Iron dust deposition causes: \[ \boxed{\text{Siderosis}} \] 

Step 3: Select the correct answer.
\[ \boxed{\text{Option (C)}} \]
