The 2010 National Training Conference on the Toxics Release Inventory (TRI) and Environmental Conditions was attended by over 250 participants representing federal, state, and tribal agencies, as well as non-governmental and other organizations. Presentations were relevant, dynamic, and addressed critical topics around toxics in communities, including environmental justice, toxic chemicals in air and water, public health, community engagement and partnerships, and tools for making environmental information accessible and easy to use.
