A) Water pollution

B) Air pollution

C) Land pollution

D) Noise pollution

Correct Answer:

B) Air pollution

Explanation:

Air pollution refers to the release of harmful substances into the atmosphere which negatively impacts human health, wildlife, and the planet itself. There are two key components of Air Pollution which include

• Chlorofluorocarbons: Found in a variety of items including refrigerants, propellants, and foam-blowing agents. Once used, the CFCs reach into the atmosphere, react with UV rays and break down into chlorine. These atoms further destroy ozone in the atmosphere and are a big reason for the ozone depletion.

• Smog: Pollutants released in the atmosphere react with gases, sunlight and more. This results in the formation of a brown or grey haze. This leads to respiratory issues, environmental damage and many more issues.

Why Not the Other Options?

A) Water pollution

• CFCs (chlorofluorocarbons) and smog affect the atmosphere rather than water bodies. Water pollution typically involves contaminants like industrial waste, oil spills, and chemicals in rivers, lakes, and oceans.

C) Land pollution

• Land pollution refers to the accumulation of solid waste, chemicals, and hazardous materials in the soil — not gaseous pollutants like CFCs and smog.

D) Noise pollution

• Noise pollution involves excessive or harmful levels of sound that disrupt human and animal life. It’s unrelated to chemical or atmospheric pollution like CFCs and smog.

FAQ’s

What are the health effects of smog?

Smog adversely affects the health of individuals especially those having asthma. It can also cause headaches, eye irritation, and lung infection. Long exposure to smog even results in increased risks of heart disease and cancer.

What steps have been taken to reduce CFC emissions?

The Montreal Protocol (1987) aimed to phase out CFC production and use. Many countries that switched to alternative, eco-friendly refrigerants are trying to reduce carbon emissions. Similar steps are being taken by many other associations to reduce CFC emissions.

How does air pollution affect global warming?

Air pollution is also caused by the greenhouse gases like CO and methane. These gases create a layer in the atmosphere trapping the heat and preventing it from leaving the atmosphere. This causes a rise in the overall global temperature.

Are there alternatives to CFCs?

Yes there. Hydrofluorocarbons and natural refrigerants like ammonia can be used instead of CFCs. Most of the countries in the world are promoting their uses too.

What is the difference between industrial and photochemical smog?

• Industrial smog – Caused by burning coal and fossil fuels. It contains gases like sulfur dioxide and soot.
• Photochemical smog – Caused by sunlight reacting with nitrogen oxides and VOCs. It contains ozone and peroxyacyl nitrates (PANs).

What is the link between air pollution and acid rain?

Sulfur dioxide and nitrogen dioxide are both relative causes of air pollution. These gases mix with the water vapor in nature and form sulphuric and nitric acid. This results in acid rain and hence air pollution could be called the cause of it.
