Canada wildfire smoke: Cincinnati's air quality is worse than Beijing, Shanghai
Air quality in Cincinnati today is worse than in Beijing and Shanghai, cities notoriously plagued by air pollution.
The air quality index in Cincinnati on Wednesday is between 135-143, a level considered unhealthy for sensitive groups, according to the World Air Quality Index project. The project has more than 30,000 stations measuring air quality in 2,000 cities across the globe.
Shanghai's air quality is 109, which is unhealthy for sensitive groups. Beijing has a rating of 69, which is considered good. Heavy industry plants in China's major cities have caused dangerous smog levels for years.
Smoke from wildfires in Canada has drifted to parts of the U.S. The Southwest Ohio Air Quality Agency issued an air quality alert through Friday night.
The affected area includes Butler, Clermont, Hamilton and Warren counties in Ohio; Boone, Campbell and Kenton counties in Kentucky and Dearborn County in Indiana.
Cincinnati isn't the only U.S. city affected. The Federal Aviation Administration grounded flights headed to in New York until Wednesday afternoon due to low visibility, CNN reported. New York's air quality reached a hazardous level, with an index of 380.
