Background:

PFOA and PFOS are persistent chemicals that are widely distributed in the environment in part because of high stability and little to no expected degradation in the environment. In terms of toxicity and exposure, PFOA and PFOS are the best studied perfluoroalkyl acids, a group of compounds used extensively over the last 50 years in commercial and industrial applications including food packaging, lubricants, water-resistant coatings, and fire-retarding foams. Through voluntary agreements, the primary manufacturer of PFOS phased out production in 2002, and PFOS is no longer manufactured in the United States. Similar arrangements have been made for PFOA, and eight companies that manufacture PFOA have committed to eliminate emissions and product content by 2015. Although emissions have been dramatically reduced, the persistence and bioaccumulation of both PFOA and PFOS result in detectable levels in the U.S. population and, therefore, these chemicals are of potential human health relevance. Several recent publications from 2012-2014 have linked PFOA and PFOS exposure to functional immune changes in humans, which are consistent with evidence of PFOA- and PFOS-related immunotoxicity in animal studies.

NTP is conducting a systematic review of the evidence for an association between exposure to PFOA or PFOS and immunotoxicity or immune-related health effects. The NTP evaluation concept for immunotoxicity associated with exposure to PFOA or PFOS was initially presented and discussed at the NTP Board of Scientific Counselors (BSC) meeting on December 10, 2014 (79 FR 62640). The NTP evaluation concept, related presentation, and BSC meeting minutes are available at http://ntp.niehs.nih.gov/go/9741. The protocol for conducting this systematic review is available at http://ntp.niehs.nih.gov/go/749926.

Request for Information:

OHAT invites the public and other interested parties to submit information on PFOA and PFOS including immune-related effects from completed and ongoing epidemiology studies, non-human animal studies, and mechanistic or in vitro studies. This information will be considered in evaluating the potential immune-related health effects of exposure to PFOA and PFOS. Information should be submitted to Dr. Yun Xie.

Request for Nomination of Scientific Experts:

OHAT invites nominations of qualified scientists to serve as members of an ad hoc expert panel to peer review the draft NTP monograph resulting from the systematic review of the evidence for an association between exposure to PFOA or PFOS and immunotoxicity. Scientists serving on the peer review panel will represent a wide range of expertise including, but not limited to, epidemiology, immunotoxicology, general toxicology, exposure assessment, and biostatistics. Each nomination should include (1) contact information for the nominee (name, affiliation, telephone number, and email), (2) curriculum vitae, and (3) a short description of the individual’s expertise such as formal academic training and experience in a relevant scientific field, publications in peer-reviewed journals, and membership in relevant professional societies. Nominations should be forwarded to Dr. Yun Xie. 

DATES:

The deadline for receipt of information and nominations of scientific experts is September 30, 2015.

ADDRESS:

Information can be submitted to xiey4@niehs.nih.gov
