Drivers in several southern Indiana counties are advised to stay away from drive-thru lanes due to the unhealthy air quality that is affecting the area. The Indiana Department of Environmental Management (IDEM) has issued air quality alerts that will last until Wednesday in response to high heat contributing to worsened ozone conditions. Similar alerts have been issued in California and Texas. Residents are urged to take precautions such as avoiding drive-thru lanes at restaurants until ozone levels return to normal. The air quality is considered unhealthy for sensitive groups when the Air Quality Index (AQI) measures between 101 and 150.
The National Weather Service (NWS) explains that air quality can vary depending on the time of day and weather conditions. Factors such as increased emissions of chemicals, faster ozone formation rates due to heat, low winds, and stagnant weather all contribute to high and persistent levels of ozone pollution. To reduce emissions that worsen ozone, people are advised to take certain actions such as avoiding drive-thrus, walking, biking, carpooling, or using public transportation. Other recommended actions include refraining from refueling a vehicle until after 7 p.m., turning off the engine when idling, and conserving energy by turning off lights or setting the air conditioner to a higher temperature.
Ozone alerts are issued when high temperatures, light winds, and other factors create conditions where high levels of ozone emissions may exceed federally mandated standards. Anyone sensitive to changes in air quality, such as children, the elderly, and individuals with heart or lung conditions, should reduce or avoid exertion and heavy outdoor work when ozone levels are high. According to AirNow, a coalition monitoring air quality, members of sensitive groups may experience health effects when the AQI is between 101 and 150. It is important for residents to be aware of these alerts and take necessary precautions to protect their health.
The IDEM alert suggests that avoiding drive-thru lanes and combining errands into one trip can help in reducing emissions that worsen ozone. Additionally, walking, biking, carpooling, or using public transportation are more environmentally friendly options. Refueling vehicles or using gas-powered equipment should be done after 7 p.m., turning off the engine when idling, and conserving energy by adjusting lighting and air conditioning settings can also contribute to better air quality. These actions not only benefit the environment but also help protect the health of vulnerable individuals who are at risk of adverse effects due to high ozone levels.
Air quality alerts are crucial for raising awareness about the impact of ozone pollution on sensitive groups, including active children, adults, and people with respiratory diseases. By taking recommended actions and following the guidelines provided by environmental authorities, individuals can contribute to improving air quality in their communities. It is essential for residents to be proactive in their efforts to reduce emissions and protect their health, especially during times when ozone levels are high. By staying informed and making informed choices, individuals can play a role in creating a healthier environment for themselves and future generations.
