What is Ozone Action Season?
During the months of May-September, our community could face unhealthy air quality levels due to an increase in ground-level ozone concentrations from single occupant vehicles. Watch for ozone alerts of orange or higher and take action!
Air Quality Index (AQI)
Pollutant Breakpoints for Ozone & Fine Particles
ppm = parts per million.NOTE:
μg/m3 = micrograms per cubic meter
Currently, Michigan's air quality usually falls into the green 'good' or yellow 'moderate' range. Air quality across the state continues to improve. Air standards recently enacted to better protect public health are much more stringent than in the past; therefore, the number of poor air quality days is expected to increase. Air monitors will reach the orange 'unhealthy for sensitive groups' range more often and occasionally reach 'unhealthy' red levels. Real-time PM2.5
(fine particle) values are shown as running averages. Past data is re-calculated as a midnight to midnight value in order to match the federal AQI calculation criteria.
High pollution levels are affecting the Greater Lansing community. The effects of ozone on your health include:
- Increase in asthma irritation
- Chest pain and difficulty in breathing
- Narrows airways, making it harder to provide oxygen to the body
- Aggravated/prolonged coughing
- Increased chance of respiratory infection
- Eye irritation
- Most vulnerable: those with pre-existing respiratory problems, children, and adults who actively exercise or work outdoors
