LAQ : Give an account of pollutants of air pollution

Question

Answer

Air pollution is caused by the release of various pollutants into the atmosphere, which can have harmful effects on human health and the environment. Some of the major air pollutants include:

1. Particulate Matter: Particulate matter is a mixture of tiny particles that can be suspended in the air. These particles can be released from natural sources such as dust storms and wildfires, but they are also produced by human activities such as industrial processes and transportation.
2. Nitrogen oxides (NOx): These are a group of gases, including nitrogen dioxide and nitric oxide, which are produced by the burning of fossil fuels in vehicles and power plants. They contribute to the formation of smog and acid rain and can cause respiratory problems.
3. Sulfur dioxide (SO₂): SO2 is produced by the burning of fossil fuels, particularly coal. It can cause respiratory problems and contribute to the formation of acid rain.
4. Ozone (O₃): Ozone is a gas that is formed when nitrogen oxides and volatile organic compounds (VOCs) react in the presence of sunlight. It is a major component of smog and can cause respiratory problems.
5. Carbon monoxide (CO): CO is produced by the incomplete burning of fossil fuels, particularly in vehicles. It is a poisonous gas that can cause headaches, nausea, and even death.
