Detergents are water pollutants because they contains

Options

A. Suphates
B. Nitrates
C. Carbonates
D. Phosphates

Answer

### Step-by-Step Solution:

1. **Understanding Pollutants**:
- Pollutants are substances that cause harm to the environment, leading to an imbalance in nature. They can be chemicals or compounds that adversely affect air, water, and soil quality.

2. **Identifying Detergents as Pollutants**:
- Detergents are classified as water pollutants because they contain certain harmful chemicals that can disrupt aquatic ecosystems.

3. **Analyzing the Components**:
- The question provides four options: sulphate, nitrate, carbonate, and phosphates. We need to evaluate each one to determine which is primarily responsible for the water pollution caused by detergents.

4. **Sulphates**:
- Sulphates can lead to air pollution and acid rain when released into the atmosphere as sulphur dioxide (SO2) from industrial emissions. However, they are not the primary concern in detergents.

5. **Nitrates**:
- Nitrates can form nitric acid when combined with water, which is harmful and can lead to water pollution. However, they are not the main component found in detergents.

6. **Carbonates**:
- Carbonates, particularly in the form of chlorofluorocarbons (CFCs), are known for their role in ozone layer degradation. They are not typically associated with detergents.

7. **Phosphates**:
- Phosphates are significant water pollutants. When introduced into water bodies, they promote excessive algae growth (eutrophication), which depletes oxygen levels and harms aquatic life. This is the primary reason phosphates are banned in detergents.

8. **Conclusion**:
- Based on the analysis, detergents are water pollutants primarily because they contain phosphates.

### Final Answer:
Detergents are water pollutants because they contain phosphates.
