SIOUX FALLS, S.D. (KELO) – The South Dakota Department of Agriculture and Natural Resources (DANR) and Department of Health have issued an air quality alert for areas of South Dakota where smoke from wildfires in Canada is forecasted to settle. 

Smoke may cause low visibility and increased fine particulate matter (PM2.5) pollution, according to a press release from state officials.

The alert will be in effect starting on Saturday and continue through Sunday, or until conditions improve. 

The DOH advises these levels may be a concern to public health. Elderly citizens, young children, and individuals with respiratory problems are the most susceptible to the smoke.

All people should avoid excessive physical exertion and minimize outdoor activities during periods of low visibility caused by the wildfire smoke. The DOH encourages people to keep indoor air clean by closing windows and doors. 

Air pollution can aggravate heart and cardiovascular disease as well as lung diseases like asthma and COPD. When the air quality is unhealthy, people with these conditions may experience symptoms like chest pain, shortness of breath, wheezing, coughing, or fatigue.

Anyone concerned about health effects related to poor air quality should contact their health care provider. 

DANR provides air quality data on the department’s website for several locations in South Dakota. Hourly PM2.5 values greater than 35 microgram per cubic meter (ug/m3) are a concern to public health.
