Elevated Respirable Particulate Levels on Train Platforms at Union Station


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.

While throwing the desktop version into a Pelican case or the other environmental enclosure works fine for short-term projects, the newer version is more rugged and designed specifically for long-term outdoor use.

Will we see stricter regulation of petroleum coke storage in the near future?

ImageAn ongoing story here in Chicago involves piles of refinery waste product known as petroleum coke, or petcoke.

For years, companies have stored uncovered piles of coal and petroleum coke on the Southeast Side near the now long gone U.S. Steel Southworks site, which was home to a number of steel mills and blast furnaces. Those mills and jobs are gone, but petcoke is still stored nearby. Most of the petcoke generated now comes from a BP refinery in Whiting which is just across the boarder in northwest Indiana.

Recently, there have been more complaints from local residents about chronic dust problems. They blame the piles of petcoke for leaving thick black grime on surrounding homes and have raised health and environmental concerns. A class-action lawsuit has even been filed alleging air pollution violations against KCBX and Beemsterboer, the companies storing the petcoke.
