Air Pollution

What are the two types of air pollutants?

• Organic and inorganic pollutants

• Natural and artificial pollutants

• Primary and secondary pollutants

• Solid and liquid pollutants

What causes nitrogen oxides to form?

• Nitrogen and oxygen coming together at high temperatures

• Chemical reactions in water bodies

• Decomposition of organic matter

• Exposure to sunlight

Which of the following is not a primary pollutant?

• Ozone

• Carbon dioxide

• Lead

• Sulfur dioxide

What contributes to the formation of photochemical smog?

• Lack of vehicular emissions

• Car exhaust exposed to sunlight

• High levels of carbon dioxide

• Low temperatures and moisture

What is the effect of particulates on human health?

• They have no significant effect on human health

• They only affect the skin

• They can contribute to asthma, heart disease, and some types of cancers

• They improve respiratory function

Which process is primarily responsible for the formation of acid rain?

• Evaporation of seawater

• Combustion of fossil fuels releasing sulfur dioxide and nitrogen oxides

• Photosynthesis in plants

• Decomposition of organic waste

How does carbon monoxide affect human health?

• It enhances oxygen transportation in the blood.

• It has no significant effect on health.

• It interferes with the blood's ability to carry oxygen.

• It promotes lung function.

What role do trees play in reducing urban air pollution?

• They release more oxygen at night.

• They absorb pollutants like carbon dioxide and release oxygen.

• They increase air temperature, reducing pollution.

• They block sunlight, reducing the formation of ozone.

How do volatile organic compounds (VOCs) contribute to air pollution?

• By directly blocking sunlight

• By acting as a primary source of oxygen

• By contributing to the formation of ground-level ozone and smog

• By reducing the amount of carbon dioxide in the atmosphere

What is the main source of sulfur dioxide in the atmosphere?

• Decomposition of plants and animals

• Volcanic eruptions

• Burning of fossil fuels by power plants and vehicles

• Photosynthesis by aquatic plants
