Title: Air Quality Advisory, Linn County, Iowa
Cedar Rapids, IA — Beginning at 2 pm Monday afternoon, Linn County Public Health observed elevated ambient levels of fine particulate matter above the daily air quality standard of 35 mg/m3. A peak hourly level of 55 mg/m3 was observed around midnight. Levels have since slowly declined to less than 35 mg/m3.
It is projected that particulate matter concentrations will remain at moderate levels for the next 24-48 hours. At these levels, the general population will find air quality to be acceptable. However, people unusually sensitive to air pollution should consider reducing prolonged or heavy exertion outdoors.
Real-time and historic ambient air quality monitoring data is posted on the Linn County Public Health Air Quality Website at www.linncleanair.org. For further questions, please contact the air quality branch at 892-6000.
