You're on a roll — Here is the article addressing air pollution for your school magazine. S.2 CHEMISTRY i) Define the key terms in air pollution Air pollution refers to the contamination of the atmosphere by harmful substances, including gases, particulate matter, and biological molecules, which can cause disease, death to humans, damage to other living organisms such as food crops, or the natural or built environment. Air pollutants are the specific substances or particles that cause this contamination. ii) Identify the causes of air pollution The primary causes of air pollution include emissions from industrial activities such as factories and power plants, exhaust fumes from vehicles (cars, trucks, buses), and the burning of fossil fuels (coal, oil, natural gas) for energy production. Other significant contributors are deforestation, which reduces the number of trees that absorb carbon dioxide, and agricultural activities like the use of pesticides and fertilizers, and livestock farming. Natural sources such as volcanic eruptions and dust storms also contribute to air pollution. iii) State the effects and corresponding mitigation to the air pollution. Air pollution has severe effects, including respiratory diseases (like asthma and bronchitis) and cardiovascular problems in humans. It also leads to acid rain, which damages forests, aquatic life, and buildings, and contributes to global warming through the greenhouse effect. Furthermore, it causes ozone layer depletion and harms plant growth. To mitigate air pollution, we must: • Promote renewable energy sources like solar, wind, and hydro power to reduce reliance on fossil fuels. • Encourage the use of public transport, cycling, and walking to reduce vehicle emissions. • Implement stricter regulations and technologies for industrial emissions, such as using scrubbers and filters. • Engage in afforestation and reforestation programs to increase carbon dioxide absorption. • Adopt sustainable agricultural practices to minimize harmful emissions.
