Wisconsin is currently facing a statewide Air Quality Advisory due to fine particulate matter from Canadian wildfire smoke. The advisory will remain in effect until noon Central Time on Thursday, as reported by the Wisconsin Department of Natural Resources (DNR).
The DNR describes the situation as “highly dynamic,” with the smoke spreading from north to south. The agency anticipates the most severe impact between noon on Tuesday and noon on Wednesday.
In a news release issued on Tuesday, the DNR emphasized the importance of closely monitoring air quality in one’s area and taking appropriate action, especially if experiencing discomfort. Both the DNR and the Wisconsin Department of Health Services advise limiting outdoor activities for all individuals and seeking indoor shelter or taking breaks if one experiences coughing and shortness of breath.
For sensitive groups, including those with heart or lung disease, older adults, children, pregnant individuals, and outdoor workers, the DNR recommends considering the relocation of all events indoors.
To stay informed about the situation, individuals can check the air quality in their area using the Environmental Protection Agency’s (EPA) Air Quality Index (AQI). The AQI measures the cleanliness or pollution levels of the air on a daily basis and focuses on five types of air pollutants. Of particular concern in this case is fine particle pollution, which can penetrate deeply into the lungs and bloodstream, causing short-term symptoms such as coughing and itchy eyes, and potentially affecting long-term lung and heart health.
The AQI ranges from zero to 500, with higher numbers indicating worse air quality. It is divided into six color-coded categories. Green or yellow (zero to 100 range) signifies relatively clear air, while orange indicates air quality concerns for sensitive groups such as children, older adults, or individuals with health conditions. Red and purple zones signify unhealthy air quality for everyone. Maroon (301 or above) represents hazardous pollution levels.
For areaspecific information, individuals can visit AirNow.gov, which provides an hourly update on air quality across the country. The website includes a real-time map and a forecast for the day ahead, gathering data from a network of air monitoring stations nationwide. Local guidance from states and cities may also offer additional information.
During periods of high pollution levels, it is advisable to take precautions such as reducing outdoor activities, using air purifiers indoors, and wearing well-fitting masks like N95 respirators when outside. Experts recommend exerting oneself less and staying properly hydrated in such conditions.
By staying informed about air quality and following the recommended measures, individuals can safeguard their health and well-being amidst the challenges posed by Canadian wildfire smoke.
