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.
