FAQs on Air Pollution & Control Video Lecture - Environmental Engineering - Civil Engineering (CE)

1. What is air pollution?
Ans. Air pollution refers to the presence of harmful substances in the air that can adversely affect human health, animals, plants, and the environment. These substances, known as pollutants, can be emitted from various sources such as vehicles, industries, power plants, and natural factors like dust storms and wildfires.
2. What are the main causes of air pollution?
Ans. The main causes of air pollution include emissions from industrial processes, vehicle exhaust, combustion of fossil fuels, burning of biomass and waste, and natural events like volcanic eruptions. These activities release pollutants such as particulate matter, nitrogen oxides, sulfur dioxide, carbon monoxide, and volatile organic compounds into the air.
3. How does air pollution affect human health?
Ans. Air pollution can have detrimental effects on human health. Breathing in polluted air can lead to respiratory problems such as asthma, bronchitis, and lung cancer. It can also worsen existing cardiovascular conditions, cause allergies, and impair lung development in children. Long-term exposure to air pollution has been linked to an increased risk of premature death.
4. What are the measures to control air pollution?
Ans. Several measures can be taken to control air pollution. These include implementing stricter emission standards for industries and vehicles, promoting the use of cleaner fuels, improving public transportation, adopting renewable energy sources, and reducing the burning of biomass and waste. Additionally, individual actions like conserving energy, carpooling, and reducing personal exposure to air pollutants can contribute to controlling air pollution.
5. How does air pollution impact the environment?
Ans. Air pollution can have significant impacts on the environment. It can harm plants by reducing their growth and productivity, damaging leaves and impairing photosynthesis. Pollutants can also acidify soils, leading to decreased fertility and impacting crop yields. Additionally, air pollution can contribute to climate change by increasing the concentration of greenhouse gases in the atmosphere, leading to global warming and other environmental consequences.
