APES Atmospheric Pollution

Front

What is carbon monoxide (CO)?

Back

A colorless, odorless gas produced by incomplete combustion, which can be deadly if inhaled.

Front

What is tropospheric ozone?

Back

An atmospheric compound that protects against UV radiation but contributes to photochemical smog and health problems when found near the ground.

Front

What is particulate matter?

Back

A type of pollution consisting of tiny particles like pollen, dander, soot, and dust, found both indoors and outdoors.

Front

Why is particulate matter of 2.5 micrometers or smaller more dangerous?

Back

It can penetrate deep into the lungs, leading to severe respiratory problems and heart disease.

Front

What are the sources and effects of sulfur dioxide (SO2)?

Back

Produced from burning coal and oil, especially in the Eastern US; causes breathing problems and is an ingredient in acid rain.

Front

What is the primary health effect of nitrogen oxides (NOx)?

Back

They can cause respiratory issues and contribute to the formation of ground-level ozone.

Front

What is the role of stratospheric ozone?

Back

It protects the Earth from harmful UV radiation.

Front

What is photochemical smog?

Back

A type of air pollution formed by the reaction of sunlight with pollutants like volatile organic compounds (VOCs) and nitrogen oxides.

Front

What are volatile organic compounds (VOCs)?

Back

Organic chemicals that can evaporate into the air and contribute to air pollution and health problems.

Front

What is acid rain?

Back

Precipitation that contains high levels of sulfuric or nitric acids, often resulting from air pollution.
