Air Quality-Comal County, Texas

Welcome to the Air Quality Health Alert Web Page

High concentrations of ground-level ozone can cause shortness of breath, coughing, wheezing, headaches, nausea, and eye and throat irritation. People who suffer from lung diseases such as emphysema, bronchitis, pneumonia, asthma and colds have even more trouble breathing when the air is polluted. These effects can be worse in children, the elderly and exercising adults.

Good 0-50	The AQI value for your community is between 0 and 50. Air quality is considered satisfactory and air pollution poses little or no risk.
Moderate 51-100	The AQI for your community is between 51 and 100. Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of individuals. For example, people who are unusually sensitive to ozone may experience respiratory symptoms.
Unhealthy for sensitive groups 101-150	The AQI for your community is between 101 and 150. Certain groups of people are particularly sensitive to the harmful effects of certain air pollutants.
