1. Pollutants

2. Six Major Air Pollutants as per the Environmental Protection Agency
Low Level Ozone
Carbon monoxide
Sulfur dioxide
Nitrogen dioxide
Particulates
Lead
What are the sources?

3. How Low Level Ozone Forms
Sunlight is the energy (sun) that causes the nitric oxides to react making ozone.

4. This ozone is a lung irritant!
Low Level Ozone
This is not the same as protective ozone
This ozone is a lung irritant!

5. Lead
Ore and metals processing and piston- engine aircraft operating on leaded aviation fuel.
People may breathe it in and particularly children, can swallow lead dust that has settled onto surfaces like soil, dust, and water.
Lead in soil and dust stays around for many years because it does not decay or decompose.

6. Sulfur Dioxide and Nitrogen Dioxide
Sulfur dioxide comes from the burning of coal and oil. It is very smelly. The main sources of SO2 are power plants
Nitrogen dioxide comes from the burning of fossil fuels (like gasoline). The main sources of NO2 are cars, trucks, and power plants.
Smog

7. Comparing Rain Water
pH value of between 5.0 and 5.5, which is slightly acidic
Carbon dioxide reacts with water forming carbonic acid
pH value between
Sulfur dioxide reacts to form sulfuric acid
Nitrogen dioxide reacts to form nitric acid
Normal Rain
Acid Rain: Increasing H+ concentration
Too much dissolving of carbon dioxide in the ocean can lead to ocean
acidification which means the pH is decreasing and the amount of H+ is
Increasing.
