Question

Give two causes of air pollution.

State two causes of air pollution.

Answer 1

1. One major cause of air pollution is vehicular emissions. Vehicles release harmful gases such as carbon monoxide, nitrogen oxides, and hydrocarbons into the air. These pollutants come from the burning of petrol and diesel, especially in areas with heavy traffic, contributing significantly to urban air pollution.
2. Another important cause is industrial pollution. Factories and power plants release smoke, chemicals, and fine particles into the atmosphere during production. This process includes pollutants like sulphur dioxide and particulate matter, which can harm human health and the environment.
