TCEQ derived oral reference doses (RfDs) for various Perfluoro Compounds (PFCs)

On June 15, 2011, the TCEQ derived oral reference doses (RfDs) for various PFCs using among other uncertainty factors, an animal-to-human UFA value of 3. However, since that time the TCEQ has finalized the 2012 TCEQ Guidelines to Develop Toxicity Factors (RG-442). Consequently, the RfDs derived in 2011 have simply been revised to reflect final TCEQ guidance concerning use of a UFA value of 1. This page contains the revised derived RfDs.
