The pollutants released by jet aeroplanes in the atmosphere as chlorofluorocarbons are called:

Explanation

**Step-by-Step Solution:**

1. **Identify the Pollutants**: The question asks about pollutants released by jet aeroplanes that are chlorofluorocarbons (CFCs).

2. **Define Aerosols**: Aerosols are tiny solid or liquid particles suspended in the air. In the context of this question, they refer to the fine mist or vapor that contains pollutants.

3. **Connection to CFCs**: CFCs are a type of aerosol that can be emitted by jet aeroplanes. Examples of CFCs include CCl2F2 (dichlorodifluoromethane) and CCl3F (trichlorofluoromethane).

4. **Impact on the Ozone Layer**: It is important to note that aerosols containing CFCs contribute to the depletion of the ozone layer in the atmosphere. This is a significant environmental concern.

5. **Conclusion**: Therefore, the pollutants released by jet aeroplanes in the atmosphere as chlorofluorocarbons are called aerosols.

**Final Answer**: Aerosols
