  1. Got Gas?????? Created By: Keaton Nicholson Nathan Boone Peter Seymour

  2. Research Question • Are the pM 2.5 levels at various gas stations significantly higher when gas is being pumped at the same stations?

  3. Background Information • PM is short for particulate matter. • Measured in 2.5 microns. • Causes of pM 2.5 • Liquids • Hydrocarbons • Soot • Dust • Acids from aerosols

  4. Background cont…… • SoucespM 2.5 • Wood stoves • Combustionsources • Gasoline emissions • pM 2.5 particles are extremely microscopic • A human hair is 50 microns • pM is smaller than 2.5 microns in size • The EPA limit for pM 2.5 is less than .035 micrograms/ cubic meter. • We spend 85% of our time indoors.

  5. Hypothesis • If we you are filling up a tank at gas station, then the pM 2.5 level will be higher than when no gas is being pumped.

  6. Methods • DustTrack to collect data • Sampled • Mike’s Conoco (6 min.) • SafeWay gas station (7 min.) • Town Pump (10 min.) • Sampled continuously • Before • During • After

  7. Mike’s Conoco Results

  8. SafeWay Results

  9. Town Pump Results

  10. Improvements • We could have filled up a full tank of gas at each station. • We could have tested when the same amount of cars were at each station. • We could have done one test when it was hot and sunny and another test when it was cold and cloudy.

  11. References

  12. Conclusion • pM 2.5 rarely exceeds the outdoor air limit • No more dangerous than taking a walk in the park. • Town Pump gives off the most emissions.
