We hope everyone is staying cool during these warm summer months. Here is a quick PSA from our Air Quality Intern Rebecca Zewdie.
Air quality is impacted by chemicals that are in the air we breathe. Some chemicals, like oxygen and nitrogen, are important for healthy air, and some chemicals are harmful to human and environmental health. Harmful chemicals are called pollutants. Some of the most common pollutants are:
- Particulate matter
- Nitrogen dioxide
- Sulfur dioxide
- Carbon monoxide
Air quality is measured by various metrics, like the air quality index, particulate matter, carbon monoxide, and volatile organic compounds.
The air quality index is a good indicator of air quality because it accounts for several pollutants in its calculations. The distribution is as below.
- 0–50: Good
- 51–100: Moderate
- 101–150: Unhealthy for sensitive groups
- 151–200: Unhealthy
- 201–300: Very Unhealthy
- 301–500: Hazardous
The most common outdoor sources of pollution are vehicle emissions, factories, wildfires, agriculture, and construction
- It is important to protect your local air quality because continuous exposure to poor air quality has harmful health effects. Short-term effects are eye, nose, and throat irritation, coughing, wheezing, and shortness of breath. Long-term effects are asthma, lung disease, heart disease, and developmental issues in children
Air Quality Tips:
- It is important to take individual action to protect yourself from poor air quality. When spending extended periods of time outdoors, check the air quality on your phone or computer. You can check Airnow.gov or a weather app for details about the air quality that day.
- If outdoor air quality is above 150, try to limit the time you spend outdoors. If you have health conditions like asthma, heart, or lung conditions, are pregnant, elderly, or a young child, you may be more susceptible to poor air quality. If you are part of one of these vulnerable groups, you should limit your time outdoors whenever the AQI is above 100.
- Summers get extremely warm in Oklahoma. It is important to take measures to stay healthy in the extreme heat. Drink plenty of water, wear light clothing and sunscreen, and try to stay in the shade whenever possible.
