Air Quality Advisory, Polk County, Iowa

Polk County, IA — Early Tuesday morning Polk County Public Works, Air Quality Division observed elevated hourly ambient levels of fine particulate matter that are above the daily air quality health standard of 35 micrograms per cubic meter. 

A change in meteorological conditions in central Iowa reduced the particulate levels below the unhealthy level.  At 7AM this morning Polk County was in the moderate category and we will continue to monitor the Canada wildfire smoke impacts in Polk County.  Polk County continuously monitors local air quality and we will provide updates as necessary over the next 24 hours. 

At these levels, the general population may find air quality to be acceptable. However, people sensitive to air pollution should consider reducing prolonged or heavy exertion outdoors. This may include people with lung or heart disease. Children active outdoors can also be sensitive to particle pollution. 

Fine and coarse particles can cause a variety of serious health problems. When exposed to these particles, people with heart or lung diseases and older adults are at increased risk for hospital and emergency room visits and in some cases, even death. These effects have been associated with short-term exposures lasting 24 hours or less. Particles can also aggravate heart disease such as congestive heart failure and lung diseases such as asthma and bronchitis.

During this period, you may reduce your exposure to particles by 1) planning strenuous activity when particle levels are forecast to be lower, 2) reducing the amount of time spent at vigorous activity, or 3) choosing a less strenuous activity (e.g., going for a walk instead of a jog).

Tips for reducing particle pollution on days when levels are expected to be high:

  • Reduce the number of trips you take in your car.
  • Avoid using gas-powered lawn and garden equipment.
  • Avoid burning leaves, trash and other materials.
