1The EPA has confirmed that Textron Inc., previously ranked at number two among the Toxic 100, has submitted data revising its 2007 TRI reporting. Based on the revision, Textron is no longer ranked among the Toxic 100. The next edition of the Toxic 100 will reflect the most current information from the EPA.

NOTE: The Toxic 100 index is based on air releases of hundreds of chemicals from industrial facilities across the United States. The rankings take into account not only the quantity of air releases, but the relative toxicity of chemicals, nearby populations, and factors such as prevailing winds and height of smokestacks. The data on chemical releases come from the U.S. Environmental Protection Agency's Toxics Release Inventory (TRI) for the year 2007, the latest data available. The data listed above was released in Aug. 2012.
