A particulate detector is visible Dec. 16 on the property of Dave Meckel near the U.S. Steel Irvin Plant in Glassport. Organizations such as the Environmental Protection Agency and Carnegie Mellon University are conducting research into the air pollution in the region.

The state is advising young children, the elderly and people with respiratory problems to limit outdoor activities Thursday in certain parts of Allegheny County.

Fine particulate matter — microscopic materials that can be inhaled and cause health problems — are anticipated in Clairton, Glassport, Liberty Borough, Lincoln and Port Vue.

As a result, the Pennsylvania Department of Environmental Protection has declared a Code Orange air quality alert, which signifies unhealthy pollution levels for sensitive groups of people. The most dangerous alert, Code Red, means unhealthy pollution levels for everyone.

According to the state, strong overnight and morning temperature inversion and light winds will contribute to the concentration of fine particulate matter in the Susquehanna Valley Area and the Liberty-Clairton Area.

Residents and businesses can help reduce air pollution Thursday by reducing or eliminating fireplace and wood stove use, avoiding open burning of leaves and trash, and avoiding use of gas-powered lawn and garden equipment, the state said.
