The Nelson A. Rockefeller Center at Dartmouth College The Center for Public Policy and the Social Sciences The Class of 1964 Policy Research Shop PFCs Regulations in New Hampshire Estephanie Aquino Ruben Gallardo Josie Yalovitser This report was written by undergraduate students at Dartmouth College under the direction of professors in the Rockefeller Center. Policy Research Shop (PRS) students produce non-partisan policy analyses and present their findings in a non-advocacy manner. The PRS is fully endowed by the Dartmouth Class of 1964 through a class gift in celebration of its 50 th Anniversary given to the Center. This endowment ensures that the Policy Research Shop will continue to produce high-quality, non-partisan policy research for policymakers in New Hampshire and Vermont. /19

The Nelson A. Rockefeller Center at Dartmouth College The Center for Public Policy and the Social Sciences The Class of 1964 Policy Research Shop What are Perfluorinated Compounds? ● PFCs are an additive that have been widely used in the manufacturing process. ● Made of carbon-fluorine bonds that increase resistance to degradation of natural processes. ● Estimated elimination half-life of 3. 5 years in human body. ● PFOAs and PFOSs are PFCs /19

The Nelson A. Rockefeller Center at Dartmouth College The Center for Public Policy and the Social Sciences The Class of 1964 Policy Research Shop Potential Health Effects of PFCs ● Low birth weights, accelerated puberty, reduced immunity. ● Possible correlation between PFOA exposure and testicular cancer, kidney cancer, increased cholesterol, changes in thyroid hormones. ● Findings are still limited due to extrapolation and epidemiological data /19
