KNOZONE ACTION DAY JUNE 17th
The Indianapolis Office of Sustainability plans to issue a Knozone Action Day for June 17 as hot, sunny weather continues with light winds. This is the first Knozone Action Day in 2021.
To protect residents and local air quality, the Office of Sustainability issues Knozone Action Days when ozone or fine particulate matter (PM2.5) levels rise above certain thresholds. During Knozone Action Days, the air quality may become unhealthy for sensitive individuals. These vulnerable groups, especially active children, the elderly, and anyone suffering from asthma, lung disease, COVID-19, or other serious health problems, should avoid spending much time outdoors.
Air pollutants like ozone and particulate matter pose a public health and environmental justice issue as they can cause increased hospitalizations, asthma, bronchitis, heart attacks, chronic obstructive pulmonary disease (COPD), and premature death, according to the American Public Health Association. 10.9% of Indianapolis residents live with asthma, and 8.6% of Indianapolis residents live with COPD; both these figures are higher than the national average.
