PHILADELPHIA (CBS) – Pennsylvania is one of two states topping the list in a new study on toxic air levels.
Out of the "Toxic 20," Pennsylvania is #2 in air pollution from coal- and oil-fired plants. Ohio ranked as the state with the most toxic air, and Florida came in behind Pennsylvania at #3.
The study, which was released by the NRDC and Physicians for Social Responsibility, used data from the Environmental Protection Agency's Toxics Release Inventory, or TRI.
Among the other key findings of the study were that nearly half of all toxic air pollution from industrial sources in the US comes from coal- and oil-fired plants, and that power plants are the biggest source of air pollution in 28 states.
