## Abstract

ABSTRACT
(Biomedical Research) Research Project 1
Project 1 is one of two Biomedical Research (BMR) Projects for the proposed “Center for Environmental and
Health Effects of PFAS” being led by North Carolina State University (NC State). Per- and polyfluoroalkyl
substances (PFAS) are common drinking water contaminants in NC and around the United States. Little is known
about how long these chemicals stay in the body or what the human health impacts are. These chemicals have
been detected in the drinking water of communities living along the Cape Fear River in NC. Working with three
community groups along the Cape Fear River, we will evaluate PFAS exposure and thyroid health effects to
people whose drinking water has been contaminated with PFAS. Disruption of thyroid hormones as well as
metabolic outcomes such as obesity have been associated with PFAS in other populations. The three
communities have exposure to different types of PFAS in their drinking water. Pittsboro, located on the Haw
River in the upper region of the Cape Fear River basin, is exposed to historically used PFAS as a result of
upstream use of firefighting foam, wastewater discharges, and land application of biosolids. The Fayetteville
private well community is located near a fluorochemical plant that discharged PFAS to both air and water (Cape
Fear River) since 1980; their wells are believed to be contaminated as a result of air transport. Wilmington, at
the mouth of the Cape Fear River and downstream of the chemical plant, is exposed to both historically used
PFAS (e.g., PFOA, PFOS) as well as a number of newly identified PFAS (e.g., GenX, Nafion byproduct 2). To
study these diverse communities, we plan to recruit 1,200 individuals in the region (300 from Pittsboro, 200 from
the Fayetteville private well community, and 700 from Wilmington) to evaluate how PFAS levels change over
time, whether personal characteristics influence PFAS level as well as excretion from the body, and whether
PFAS, either individually or as a group, influence thyroid outcomes. We plan to include individuals ages 6 and
over who have lived in the region since July 2016. We will invite participants to clinic visits in Years 1 and 3 to
collect blood and urine samples for PFAS and clinical analyses, administer questionnaires to obtain information
on water use history, demographic characteristics, and medical and health outcomes. Working with our
community partners, we will report back individual and community-level results on a regular basis. We will have
Community Science Advisory Boards in each community to provide input to the study and ensure that the study
investigators are well informed about community concerns. We anticipate finding PFAS mixtures in each
community; we will use statistical approaches that allow us to evaluate individual PFAS while taking into account
the complex mixture present. This study, with its complex mix of PFAS and racially diverse sample, will provide
key insights to the human ...
