9.1 What is Air

Air pollution

Human sources


Air

Made up of gases

  • Nitrogen

  • Oxygen

  • Humidity (water)


Dirty air
Dirty Air

  • Unhealthy gases

  • From cars, electricity, factories


Particulate matter
Particulate Matter

Primary Air Pollution

Secondary Air Pollution

Made afterbeing released into the atmosphere

Smog

Ozone

Acid rain

  • Released directly into the air.


Outdoor air pollution
Outdoor Air Pollution

  • Measured by Air Quality Index

  • Each day various air pollutants are collected

  • Each geographic area gets an AQI #

  • Watch weather reports!


Indoor air quality
Indoor Air Quality

  • Air inside homes/ buildings

  • Worse that outdoors- enclosed


HEPA

  • Filters airborn particles

  • Vacuum or furnace


Breathing
Breathing

  • Pollutants cause health problems for people, plants, and animals


Respiratory system
Respiratory System

  • +600,000 / year die from air pollution

  • Asthma (allergies)

  • Emphysema (smoking)


Aquatic life
Aquatic Life

Carbon Dioxide dissolves in water

  • Increases the growth of algae

  • Dead algae smells odorous and reduces oxygen

  • Kills fish

  • Decreases he pH (acidic)

  • Dissolves coral and the shells

Aquatic Life

NOx and SOx

  • Cause acid rain


Acid rain
Acid Rain

  • Destroys metal and stone

Acid Rain

  • Kills fish

Aquatic Life

Particulate matter

  • Kill fish and other organisms


E missions
Emissions

  • Substances released into the air from……

  • Burning coal, gasoline, natural gas

  • Volcanoes/ Lightning

  • Industrial and utility


Ways to reduce emissions
Ways to Reduce Emissions
