- Hazardous: 250.5 µg/m³ or higher
Ozone (O3): The Invisible Pollutant with a Stealthy Impact
Ozone, a colorless, pungent gas, forms when sunlight reacts with pollutants like nitrogen oxides and hydrocarbons in the atmosphere. This process, known as photochemical smog, is particularly common during warm, sunny summer days.
Ozone’s insidious nature lies in its ability to irritate the lungs and airways. Short-term exposure can cause a tickle in the throat, a scratchy cough, and shortness of breath. Prolonged exposure, however, poses more severe risks, increasing the likelihood of bronchitis and asthma attacks. Even more alarmingly, it can damage the lungs permanently, reducing their capacity and impairing overall respiratory health.
In addition to its direct impact on the respiratory system, ozone also contributes to premature aging and immune system dysfunction. It’s a particular concern for individuals with preexisting respiratory conditions, those engaging in strenuous outdoor activities, and children whose developing lungs are more susceptible to damage.
To assess ozone levels and their associated health risks, the Environmental Protection Agency (EPA) has established Air Quality Index (AQI) categories. When ozone concentrations exceed good levels, they can reach moderate, unhealthy for sensitive groups, unhealthy, very unhealthy, and hazardous. Understanding these categories and monitoring real-time AQI data is crucial for making informed decisions about outdoor activities and protecting oneself from the adverse effects of ozone pollution.
Nitrogen Dioxide (NO2): A Silent Threat to Asheville’s Air Quality
Nitrogen dioxide (NO2) is an invisible gas that primarily originates from the burning of fossil fuels. In Asheville, NO2 emissions stem from vehicles, power plants, and industrial activities.
