SHOREVIEW, Minn., Nov. 10, 2015 /PRNewswire/ -- A recent study performed by the U.S. Environmental Protection Agency (EPA) this past summer outfitted scientists with the SidePak™ Personal Aerosol Monitor AM510 to collect and compare ambient air samples in various locations within Chicago's Union Station. The study was initiated in response to concerns about air quality on Union Station's train platforms.
The study, taking place over a three week period between the hours of 6 a.m. and 6 p.m, revealed elevated fine particulate matter (PM2.5) in the air on the train platforms. The highest concentrations were found during rush hour periods, the higher average concentrations were on the south platform than on the north and short-term localized peak concentrations were identified near locomotives.
With this study, the EPA, working with Metra, Amtrak and various impacting building ventilation representatives, is determining if there is a need to optimize existing ventilation systems, add additional systems or change operational procedures to reduce particulate emissions. The EPA recognizes fine particulate pollution (PM2.5) is a major contributor to serious health problems, including respiratory disease, cardiovascular disease, aggravation of asthma and lung cancer.
