Which of the following is not pollution related disorder?

Options

A. Silicosis
B. Pneumoconiosis
C. Flourosis
D. Leprosy

Answer

To determine which of the following options is not a pollution-related disorder, we will analyze each option provided:

1. **Silicosis**:
- Silicosis is a respiratory disorder primarily caused by inhaling fine silica dust, often found in industries such as stone grinding and mining. It is classified as an occupational respiratory disorder. Since it is directly related to exposure to mineral dust, it is indeed a pollution-related disorder.

2. **Pneumoconiosis**:
- Pneumoconiosis is a general term for lung diseases caused by the inhalation of various types of dust, including silica. Silicosis is a specific type of pneumoconiosis. Therefore, pneumoconiosis is also related to pollution, making it another incorrect option.

3. **Fluorosis**:
- Fluorosis is caused by excessive exposure to fluoride, often through contaminated water sources. This condition affects the teeth and bones, leading to mottling and discoloration of teeth. Since it is related to water pollution, fluorosis is also a pollution-related disorder.

4. **Leprosy**:
- Leprosy is an infectious disease caused by the bacterium Mycobacterium leprae. It is not caused by environmental pollution but is instead a contagious disease that affects various organs, including the skin and nerves. Therefore, leprosy is not related to pollution.

**Conclusion**: The correct answer is **leprosy (Option D)**, as it is not a pollution-related disorder.
