Last summer, the U.S. Environmental Protection Agency conducted an air quality survey at Union Station in Chicago. The results showed elevated concentrations of respirable particulate matter (PM2.5) in ambient air on train platforms and nearby streets.
PM2.5 is a mixture of liquid droplets and particles measuring 2.5 micrometers in diameter or smaller. These tiny particles can be inhaled deep into the lungs where they can enter the bloodstream and cause serious health problems. The risk is even more severe for youth, the elderly and those with respiratory conditions like asthma.
Do workers in your offices suffer from long bouts of sneezing, sniffling, cough, sore throat, itchy or red eyes and skin, or fatigue — for no explainable reason?
The mold and pollen counts are low. But workers complain of headaches, stuffed noses, itchy eyes, and breathing problems. Do they say they feel better at home in the evenings or on weekends, or when they leave the office during lunch? Is it just cold season, or an environmental illness caused by exposure to respirable particles or chemicals?
