March 5, 2010 by editor


High fine particulate pollution in eastern Iowa has prompted the Iowa Department of Natural Resources (DNR) to issue an air quality alert for east central Iowa Thursday (3/4) and extending into late today (3/5).
The U.S. Environmental Protection Agency’s (EPA) 24-hour health standard of 35 micrograms per cubic meter was exceeded Thursday in Waterloo (36) and Iowa City (40). Readings as high as 50 were recorded during the period in Cedar Rapids, Iowa City and Muscatine.
Because of the high particulate levels, residents with respiratory or heart disease, the elderly and children were warned to limit prolonged outdoor activity.

MUSCATINE, Iowa – Fine particle pollution levels were recorded above the Environmental Protection Agency health threshold in Muscatine and other Iowa cities this morning.
Elevated fine particle levels are expected to persist until late Friday morning, according to the Iowa Department of Natural Resources.
Iowans living in east central Iowa with respiratory or heart disease, the elderly, and children should limit prolonged outdoor exertion until air quality conditions improve, the DNR said.
EPA’s 24-hour health threshold for fine particles is 35 micrograms per cubic meter. As of noon today, fine particle levels averaged in the high 30s to low 40s across parts of east-central Iowa. Monitors recorded fine particulate levels at 45 in Cedar Rapids, 50 in Iowa City, 50 in Muscatine and 49 in Waterloo.
An air monitor in Waterloo recorded a 24-hour fine particle level Wednesday of 36, and a monitor in Iowa City recorded a level of 40.
Fine particles are emitted by vehicle traffic and other combustion sources, and are formed by chemical reactions in the atmosphere. Stagnant air masses confine fine particles, and pollutant levels rise. 
The fine particle levels in the state have been following a pattern of rising rapidly during the evening and nighttime hours, and falling back to levels below the standard in late morning or early afternoon. This cycle is expected to continue until winds pick up Friday afternoon.
