IRIS Toxicological Review of Libby Amphibole Asbestos (Final Report)
Overview
Citation
Background
The final health assessment of the toxicity of Libby amphibole asbestos was prepared by staff in both EPA’s Region 8 Office and Office of Research and Development's National Center for Environmental Assessments (NCEA). The assessment is focused on a specific type of asbestos found as a consequence of the mining and processing of vermiculite in Libby, Montana. The assessment is also included on EPA's IRIS data base.
The project supports OSWER and Region 8 site clean-up and related risk management initiatives at the Libby Superfund site. As with all IRIS assessments, the development of the external peer review draft document required internal EPA review and OMB/interagency review. After an independent external peer review, the draft final document underwent a second round of EPA and OMB/interagency review before being finalized and included in the IRIS data base.
