Ozone Formation

Ozone Formation. Kristen Keenan Erzsebet Pocsi. “BAD” Ozone. Reaction with N0x (nitrogen oxides): N02 + O2  O3 + NO this reaction requires sunlight Reaction with VOCs (volatile organic carbons):  VOCs + NO  NO then N02 + O2  O3 + NO this reaction requires sunlight.

Presentation Transcript

  1. Ozone Formation Kristen Keenan Erzsebet Pocsi

  2. “BAD” Ozone • Reaction with N0x (nitrogen oxides): • N02 + O2  O3 + NO this reaction requires sunlight • Reaction with VOCs (volatile organic carbons): •  VOCs + NO  NO then • N02 + O2  O3 + NO this reaction requires sunlight

  3. Health Effects • Shortness of breath • Dry cough • Pain when taking a deep breath • Tightness of chest • Wheezing • Nausea • Trigger asthma • Aggravate respiratory illnesses

  4. Calibration of Simplified Model

  5. AQI Probability Distribution for Saint-Louis Probability = count of O3 AQI > 100 total days observed P = .132 = 52 395

  6. AQI’s Probability Distribution • Know: • Recorded AQIs • Recorded weather on each corresponding day • Correlate climate and AQI • Knowing climate can predict AQI
