media

​Aside from providing us with the gasses needed for life, the atmosphere also:

  • Blocks UV radiation

  • Moderates the climate

  • Redistributes water vapor through the hydrologic cycle​

Our Atmosphere

media

These are the harmful substances emitted DIRECTLY into the atmosphere

  • ​Hydrocarbons

  • Ni​trogen oxides, sulfur oxides, carbon oxides

  • ​Hazardous air pollutants

  • Particulate matter​

Primary Pollutants

​These harmful substances form when primary pollutants and natural gasses in the atmosphere react

  • Sulfuric acid

  • Ozone​

​​Secondary Pollutants

media

5

media

Nitrogen oxides (NOx)- Released into the atmosphere through burning of fossil fuels and natural processes.

  • Cause difficulty breathing

  • React in the atmosphere to form secondary pollutants including nitric acid and ozone​

Primary Pollutants

6

media

Sulfur oxides- React in the atmosphere to form sulfuric acid (acid rain). The trees in the picture show the effects of acid rain on plant life.

Carbon oxides- Two forms

  • Carbon monoxide (toxic gas)

  • Carbon dioxide (greenhouse gas)​

Primary Pollutants

7

media

Hydrocarbons- Molecules such as methane and benzene​​

  • Can cause a variety of health effects including injury to respiratory tract and cancer.

Air Particulates- Small particles that float in the air

  • Dust, asbestos, viruses, etc

  • can cause health issues such as cancer and damage lungs and arteries​

Primary Pollutants

Multiple Choice

What type of atmospheric pollution are emitted directly into the atmosphere?

1

Primary pollutants

2

Major pollutants

3

Secondary pollutants

4

Stationary pollutants

9

Multiple Choice

Greenhouse gasses such as methane (CH4) are what type of primary pollutant?

1

Nitrogen oxides

2

Particulate matter

3

Hydrocarbon

4

Carbon oxides

10

Multiple Choice

Primary pollutants cause....

1

Adverse health issues

2

Global warming

3

Damage to terrestrial life

4

All of these are correct

11

Produced when sulfur oxides and nitrogen oxides react with water vapor producing acid rain

  • Sulfuric acid

  • Nitric acid​

Acids

Ozone is produced naturally in the high in the stratosphere but is harmful when produced near the ground

Recipe:

NOx + Hydrocarbons + Sunlight

Ozone

Major Secondary Pollutants​

Blocks UV radiation when in the stratosphere

4

Beneficial to humans in the troposphere
