Air pollution refers to the presence of harmful substances in the atmosphere, including gases, particles, and biological molecules, that degrade air quality and pose risks to human health and the environment. Major sources include vehicle emissions, industrial processes, agricultural activities, and burning of fossil fuels, which release pollutants such as carbon monoxide, sulfur dioxide, nitrogen oxides, particulate matter (PM2.5 and PM10), and volatile organic compounds.
These pollutants contribute to a range of health issues, including respiratory diseases like asthma and bronchitis, cardiovascular problems, and even premature death. Environmentally, air pollution leads to acid rain, ozone depletion, reduced visibility, and climate change by trapping heat in the atmosphere. In urban areas, smog and haze are common, while global impacts include altered weather patterns and biodiversity loss.
Efforts to combat air pollution involve regulatory measures, such as emission standards and clean air acts, alongside technological innovations like electric vehicles and advanced filtration systems. Individual actions, including reducing car use, conserving energy, and planting trees, also play a vital role in improving air quality and fostering sustainable practices. Monitoring through air quality indexes helps track progress and inform public health responses.

1. Question: What is the primary source of sulfur dioxide (SO₂) in the atmosphere?
Options:
A) Volcanic eruptions
B) Fossil fuel combustion
C) Deforestation
D) Agricultural activities
Answer: B
Explanation: Sulfur dioxide is mainly released from the burning of fossil fuels like coal and oil in power plants and industrial processes, contributing significantly to air pollution and acid rain.
2. Question: Which gas is the most abundant greenhouse gas in the Earth’s atmosphere?
Options:
A) Carbon dioxide (CO₂)
B) Methane (CH₄)
C) Water vapor (H₂O)
D) Nitrous oxide (N₂O)
Answer: C
Explanation: Water vapor is the most abundant greenhouse gas, trapping heat in the atmosphere and amplifying the effects of other pollutants like CO₂.
3. Question: What is the main component of photochemical smog?
Options:
A) Sulfur dioxide
B) Ozone
C) Carbon monoxide
D) Particulate matter
Answer: B
Explanation: Photochemical smog forms from reactions between sunlight, nitrogen oxides, and volatile organic compounds, producing ground-level ozone as a key harmful component.
4. Question: Which of the following is a primary health effect of prolonged exposure to fine particulate matter (PM2.5)?
Options:
A) Skin irritation
B) Respiratory diseases
C) Bone disorders
D) Eye infections
Answer: B
Explanation: Fine particulate matter can penetrate deep into the lungs, leading to respiratory issues such as asthma, bronchitis, and increased risk of lung cancer.
5. Question: What is the main source of carbon monoxide (CO) pollution in urban areas?
Options:
A) Industrial emissions
B) Vehicle exhaust
C) Forest fires
D) Volcanic activity
Answer: B
Explanation: Incomplete combustion of fossil fuels in vehicles releases carbon monoxide, which reduces the blood’s ability to carry oxygen and poses risks in high-traffic areas.
6. Question: Which international agreement primarily addresses the reduction of ozone-depleting substances?
Options:
A) Kyoto Protocol
B) Montreal Protocol
C) Paris Agreement
D) Basel Convention
Answer: B
Explanation: The Montreal Protocol phases out the production and use of chemicals like CFCs that deplete the ozone layer, thereby reducing related air pollution.
7. Question: How does nitrogen oxides (NOx) contribute to air pollution?
Options:
A) By forming acid rain
B) By depleting oxygen levels
C) By causing water pollution
D) By increasing biodiversity
Answer: A
Explanation: Nitrogen oxides react with water vapor to form nitric acid, a component of acid rain, which damages ecosystems, buildings, and water bodies.
8. Question: What is a common method to reduce indoor air pollution from cooking in developing regions?
Options:
A) Using open fires
B) Installing ventilation systems
C) Burning more wood
D) Sealing windows
Answer: B
Explanation: Ventilation systems, such as chimneys or improved stoves, help remove pollutants like smoke and particulate matter from indoor environments.
9. Question: Which pollutant is primarily responsible for the formation of acid rain?
Options:
A) Carbon dioxide
B) Sulfur dioxide
C) Ozone
D) Methane
Answer: B
Explanation: Sulfur dioxide, when released into the atmosphere, combines with water to form sulfuric acid, leading to acid rain that harms forests, lakes, and soil.
10. Question: What role do volatile organic compounds (VOCs) play in air pollution?
Options:
A) They cool the atmosphere
