The Oregon Department of Environmental Quality issued an air quality health advisory for multiple counties due to wildfire smoke spreading across the region, with the worst air quality remaining east of the Cascades. The advisory warns that wildfire smoke contributes to ground-level ozone pollution, which can aggravate respiratory conditions including asthma and cause symptoms like chest pain, coughing, and shortness of breath. Sensitive groups including children, pregnant people, older adults, and those with heart or respiratory conditions are particularly at risk. The DEQ recommends limiting outdoor activities during peak ozone hours, wearing N95 masks when outside, and avoiding activities that generate pollution such as driving.
