APES Unit 7: Atmospheric Pollution

Front

What is atmospheric pollution?

Back

Atmospheric pollution refers to the presence of harmful substances in the air that can cause adverse effects on human health, the environment, and the climate.

Front

What are the primary sources of air pollution?

Back

Primary sources include vehicle emissions, industrial discharges, burning of fossil fuels, and natural events like volcanic eruptions.

Front

What is a catalytic converter?

Back

A catalytic converter is an emission control device in vehicles that reduces harmful gases by converting them into less harmful substances.

Front

What role do thermal inversions play in air pollution?

Back

Thermal inversions trap pollutants close to the ground, leading to increased concentrations of smog and other harmful substances.

Front

What is the significance of coal burning power plants in atmospheric mercury production?

Back

Coal burning power plants are the largest source of atmospheric mercury, which can accumulate in the food chain and pose health risks.

Front

Define noise pollution.

Back

Noise pollution is the excessive or harmful levels of noise in the environment, often caused by traffic, industrial activities, and urbanization.

Front

How do volcanic eruptions contribute to air pollution?

Back

Volcanic eruptions release ash, gases, and aerosols into the atmosphere, which can affect air quality and climate.

Front

What is an electrostatic precipitator?

Back

An electrostatic precipitator is a device used to remove particles from exhaust gases in industrial processes, helping to reduce air pollution.

Front

What are volatile organic compounds (VOCs)?

Back

VOCs are organic chemicals that can evaporate into the air and contribute to air pollution, often found in paints, solvents, and fuels.

Front

Explain the concept of acid deposition.

Back

Acid deposition refers to the falling of acids from the atmosphere to the ground, primarily due to sulfur dioxide and nitrogen oxides from burning fossil fuels.
