The Minnesota Pollution Control Agency issued an air pollution health alert Saturday afternoon for the southern two-thirds of the state.
The MPCA says fine particle pollution levels are elevated at monitoring sites in Detroit Lakes, Brainerd, St. Cloud, Marshall, Rochester and the Twin Cities. Fine particle pollution may reach levels considered unhealthy for people who are sensitive to air pollution.
Exposure to high levels of fine particles may worsen pre-existing health conditions and may cause chest pain, shortness of breath, wheezing, coughing and fatigue.
Fine particles come from combustion sources such as vehicle exhaust and wood burning.
The alert is set to expire at noon Sunday. Air quality is expected to return to good conditions Monday as a cold front moves into the state.
