We have another month until it’s official, but it already feels like summer in the Midlands. Here in the Midlands, summers are known for festivals, homemade ice cream and playing in Lake Murray. But there’s something else that heats up when the Midlands starts getting warmer: ground-level ozone. Here’s the dirt on ground-level ozone:
Good up high. Bad nearby. Unlike the good, protective ozone layer in the stratosphere, ground level ozone is a harmful air pollutant that affects all of us. It’s formed when emissions from everyday items combine with other pollutants and “cook” in the heat and sunlight. (Gasoline-powered cars and trucks are the most common source of emissions in our area.) Weather also plays a key role in ozone formation. The highest ozone levels are usually recorded in summer months when temperatures approach the high 80s and 90s and the wind is stagnant or light.
Ground-Level ozone affects everybody. At ground level, ozone is a health hazard for all of us, especially the young and elderly. Those who are active and exercising outdoors may experience breathing difficulties and eye irritation. Prolonged exposure may result in reduced resistance to lung infections and colds. Ozone can also trigger attacks and symptoms in individuals with pre-existing conditions, like asthma or other respiratory infections like chronic bronchitis and chronic obstructive pulmonary disease (COPD).
Stay alert all summer. Remember, the highest ozone levels are typically found on days that reach the high 80s and 90s and when the wind is stagnant or light. Stay tuned to your local meteorologists, as they will be notifying the public of Ozone Action Alert days when ozone levels are forecasted to reach unhealthy levels.
