Which of these is a pollution related occupational health hazard?

Options

A. Flurosis
B. Pneumoconieosis
C. Silicosis
D. Asthma

Answer

To solve the question "Which of these is a pollution related occupational health hazard?", we will analyze each option provided.

### Step 1: Analyze the Options
The options given are:
1. **Fluorosis**
2. **Pneumonoconiosis**
3. **Silicosis**
4. **Asthma**

### Step 2: Evaluate Each Option
- **Fluorosis**: This condition is caused by excessive intake of fluorides, leading to dental issues, particularly in children. It is not specifically related to occupational exposure, hence it is **not** considered an occupational health hazard.

- **Pneumonoconiosis**: This is a lung disease caused by inhaling coal dust or cotton fiber dust. Workers in industries like coal mining or textile manufacturing are at risk. Therefore, this condition is directly related to occupational exposure and is considered an occupational health hazard.

- **Silicosis**: This disease is caused by overexposure to silica dust, commonly found in industries that work with mineral ores such as quartz and mica. Workers in these industries are at risk of developing silicosis, making it another occupational health hazard.

- **Asthma**: While asthma can be triggered by various allergens and irritants, it is not exclusively an occupational disease. It can be caused by environmental factors unrelated to specific occupations.

### Step 3: Conclusion
Based on the analysis:
- The correct answers are **Pneumonoconiosis** and **Silicosis**, as both are pollution-related occupational health hazards.

### Final Answer
**Pneumonoconiosis and Silicosis are pollution-related occupational health hazards.**
