Iowa Air Quality Hits 'Very Unhealthy' Levels
13 Feb
Summary
- Air quality in Iowa reached 'very unhealthy' levels on Thursday morning.
- Over 150,000 people were impacted by the severe air pollution.
- The exact cause of the widespread poor air quality remained unclear.
Air quality across parts of Iowa and Illinois was deemed "very unhealthy" on Thursday morning, necessitating advisories for residents to remain indoors. The Environmental Protection Agency's (EPA) AirNow website reported elevated pollution levels, particularly affecting Davenport, Iowa, and extending into northwestern Illinois, a region encompassing over 150,000 individuals.
The Air Quality Index (AQI) in Davenport reached a high of 281, a level indicating a significant increase in health risks for all populations. The EPA recommended that everyone, especially those with pre-existing heart or lung conditions, older adults, children, and teenagers, limit outdoor activities. Everyone else was advised to avoid strenuous exertion outside.
Despite the "very unhealthy" air quality being reported by various agencies, including the Iowa Department of Natural Resources (DNR), the precise cause of the pollution was not immediately identified. While prescribed burns were conducted the previous day, officials had not received specific communications linking them to the current air quality concerns.
Further analysis revealed elevated levels of nitrogen dioxide, particulate matter, and fine particulate matter. Exposure to these pollutants can lead to coughing, breathing difficulties, aggravated asthma, and the development of chronic respiratory diseases. As of midday Thursday, Davenport's air quality monitors indicated the poorest conditions nationwide, with other cities like Phoenix and St. Louis experiencing "unhealthy for sensitive groups" levels.
