The Evansville Environmental Protection Agency and the Vanderburgh County Health Department have issued OZONE ALERTS for Saturday, May 19 & Sunday, May 20 because ambient concentrations of ozone may reach or exceed the level of the National Ambient Air Quality Standard (NAAQS) for ozone and within the Unhealthy for Sensitive Groups range. Ozone levels for Friday, May 18 may reach the “high Moderate” level. Air quality forecast for Monday, May 21 will be announced on Monday. The current ozone NAAQS was set by the U.S. EPA in 2008 at an eight-hour average of 76 parts per billion (ppb). Per the Air Quality Index (AQI), eight-hour ozone levels between 76 to 95 ppb are considered to be Unhealthy for Sensitive Groups such as children and active adults, and people with respiratory diseases like asthma. http://www.epa.gov/airnow/ozone-c.pdf
Within a few hours or days, exposure to higher levels of ozone can cause lung and throat irritation, shortness of breath, increase the frequency of asthma attacks and aggravate respiratory diseases such as asthma, emphysema and bronchitis. Children, active adults, and people with respiratory diseases should limit prolonged outdoor exertion especially between 12:00 p.m. to 6:00 p.m. when ozone levels are highest.
NO OPEN BURNING is allowed during Ozone Alerts. The use of gas and charcoal grills is permitted, but we encourage postponing grilling until air quality improves.
