Most atmospheric pollutants do not rise above

Options

A. 600 m
B. 1000 m
C. 2000 m
D. 200 m

Answer

**Step-by-Step Solution:**

1. **Understanding Atmospheric Pollutants**: Atmospheric pollutants are substances that degrade air quality and can include gases and particulate matter. Common pollutants include carbon monoxide, lead, nitrogen oxides, ground-level ozone, particulate matter, and sulfur oxides.

2. **Pollutant Concentration Levels**: The concentration of these pollutants is highest near the ground. As we move higher into the atmosphere, the concentration of these pollutants decreases.

3. **Identifying the Maximum Height**: According to the information provided, the maximum concentration of atmospheric pollutants is typically found at around 200 meters above the land surface. However, pollutants can rise up to 600 meters before their concentration significantly decreases.

4. **Evaluating the Options**:
- **200 meters**: This is where pollutants are most concentrated.
- **600 meters**: This is the maximum height up to which pollutants can rise before their concentration decreases.
- **1000 meters and 2000 meters**: These heights are above the maximum concentration level for pollutants.

5. **Conclusion**: The correct answer to the question "Most atmospheric pollutants do not rise above" is **600 meters**.
