Air Pollution and Health Effects

The video provides a comprehensive review of Unit 7 in AP Environmental Science, focusing on air pollution. It covers the differences between pollution and pollutants, details the six major pollutants regulated by the Clean Air Act, and explains the formation of photochemical smog and thermal inversions. The video also offers tips for tackling FRQs, outlines exam basics, and discusses indoor air pollutants. Additionally, it provides study resources and preparation strategies for the AP exam.

What is the main topic covered in Unit 7 of the AP Environmental Science exam?

• Water Pollution

• Air Pollution

• Soil Pollution

• Noise Pollution

When identifying a hypothesis in an FRQ, which format should you use?

• The DV will not change

• The IV will remain constant

• Increasing or decreasing the IV will decrease or increase the DV

• The IV and DV are unrelated

What is the role of a control group in an experiment?

• To be manipulated in every possible way

• To receive varying levels of the dependent variable

• To serve as a baseline for comparison

• To receive the highest level of the independent variable

Which of the following is NOT considered an air pollutant under the Clean Air Act?

• Carbon Dioxide (CO2)

• Sulfur Dioxide (SO2)

• Nitrogen Oxides (NOx)

• Carbon Monoxide (CO)

What is a common source of Nitrogen Oxides (NOx)?

• Gasoline Vehicles

• Coal Combustion

• Waste Incineration

• Metal Manufacturing

What is the primary source of NO2 that contributes to photochemical smog?

• Car exhaust

• Natural gas

• Industrial emissions

• Coal combustion

How do volatile organic compounds (VOCs) affect the formation of photochemical smog?

• They break down ozone

• They combine with NO to form photochemical oxidants

• They reduce the rate of photosynthesis

• They increase the amount of NO2 in the atmosphere

What happens during a thermal inversion?

• Cold air traps warm air and pollutants near the surface

• Warm air rises and disperses pollutants

• Pollutants are carried away by wind

• Sunlight breaks down pollutants

Which indoor air pollutant is known to cause cancer and comes from old insulation?

• Carbon monoxide

• Asbestos

• Radon gas

• Lead

What is the main health effect of carbon monoxide poisoning?

• Headaches

• Eye irritation

• Respiratory irritation

• Suffocation
