Wildfire Smoke Impacts Air Quality in Wisconsin
Wildfire smoke from Canada and Minnesota has significantly impacted air quality in Wisconsin, with particulate matter levels rising to dangerous levels. According to Bart De Stasio, professor emeritus of biology at Lawrence University, particulate matter smaller than 2.5 micrometers can penetrate deep into the lungs, causing respiratory issues. The U.S. Environmental Protection Agency warns that an air quality index (AQI) of 200 or higher is considered unhealthy for outdoor activities. This summer, Green Bay officials even closed Bay Beach Amusement Park for two days due to hazardous air conditions. Experts note that the frequency and intensity of wildfires have increased, exacerbating the problem. Prescribed burns, used for land management, also contribute to the smog, which can cross state and national borders, further deteriorating air quality.
