The Multi-Site PFAS Health Study

About

Researcher Erin Bell, discusses the study with local residents outside of the Hoosick Falls study clinic.

The Multi-Site PFAS Health Study (MSS), a national health study, examined the role per- and polyfluoroalkyl substances (PFAS) may play in various health outcomes. The MSS began data collection in the City of Newburg and in the Hoosick Falls area in the winter of 2021. Study visits took place at local study clinics from the Winter of 2021 through Fall of 2023. A total of 523 adults and children in the City of Newburgh and in the Hoosick Falls area participated in the study. The success of the study would not have been possible without input and assistance from our Community Advisory Panel (CAP) and numerous community members and groups.

The study was funded by the Centers for Disease Control and Prevention (CDC) and the Agency for Toxic Substances and Disease Registry (ATSDR). New York’s effort was led by researchers at the University at Albany and the New York State Department of Health (NYSDOH). 

 

Study Investigators

Dr. Erin Bell, PhD 

Dr. Bell is a Professor of Environmental Health Sciences at the University at Albany College of Integrated Health Sciences. Her research interests include examining the association of environmental exposures and adverse birth and child health outcomes, including neurodevelopment. She is particularly interested in the relationship between social factors and environmental exposures and their combined impact on child development. For more information, please visit Dr. Bell's faculty page.

Steven Forand, MS

Mr. Steven Forand is the Section Chief, Research Scientist IV in the Bureau of Environmental and Occupational Epidemiology (NYSDOH). Mr. Forand has extensive experience working on environmental health studies and surveillance projects and community health investigations related to environmental exposures. He holds a MA in Biology from Binghamton University and a MS in Epidemiology from the University at Albany. 

Dr. Elizabeth L. Lewis-Michl (former NYSDOH Co-Principal investigator)

Dr. Lewis-Michl was the Director of the Division of the Environmental Health Assessment within the Center for Environmental Health at the New York State Department of Health (NYSDOH).

Study Analysis Updates

Our original clinic sites in the City of Newburgh and the Hoosick Falls area closed in May of 2023. In a final effort to allow more opportunity for residents in the City of Newburgh to participate, a summer clinic was in operated from July 2023-Spetember 2023. A total of 12,722 invitation letters were sent out to both communities. 750 people called into our office to be screened for eligibility. 652 of those individuals were eligible and 98 were ineligible. We had a total of 526 clinic visits and collected 519 urine samples, 515 blood samples and interviewed 523 participants!

The MSS PFAS study tested for the following PFAS:

  • MeFOSAA
  • PFHxS
  • PFOA (linear and branched isomers)
  • PFDA
  • PFUnDA
  • PFOS (linear and branched isomers)
  • PFNA in serum

As information from data collection becomes available, it will be provided on this website as well as at presentations provided in affected communities.

PFAS Test Results Information

The National Academies of Sciences, Engineering, and Medicine (NASEM) provides independent and trustworthy advice and solutions to complex problems by using expert knowledge from the science, engineering, and medicine field. NASEM guidance divided the serum PFAS levels into three different categories: <2 (ng/mL), 2 - <20 (ng/mL), and ≥20 (ng/mL). This guidance was made to help clinicians interpret the results and inform clinical care. No adverse health effect is expected below 2 (ng/mL), and a potential for adverse health effects is expected between2 - <20 (ng/mL) especially among sensitive populations, whereas an increased risk of adverse effects is seen above 20 (ng/mL). In the tables provided we used the three categories created by NASEM and divided the PFAS serum levels measured in adult participants from the NY site of the Multi-site PFAS Health Study (MSS study) total as well as by area. The National Health and Nutrition Examination Survey (NHANES) provides information on the general population. Table 1 shows 45.4% of participants in our MSS study had a level above 20 ng/mL which was almost 3.39 times as many as in the general population (14.7%). These people are more likely to have adverse health effects compared to the other groups. 52.7% of MSS participants had moderate PFAS levels, compared to 82.9% in the general population. This is largely due to the large number of MSS participants in the higher category (≥20ng/mL). Only 1.9% of MSS participants had PFAS level below 2 ng/mL which is similar to the NHANES population. Table 2 includes PFAS levels for MSS study participants by area.  

The PFAS levels of child participants were not included due to low participation, but results were similar to children in the general population.

Community

 

Community Advisory Panel

As part of this study, UAlbany and the New York State Department of Health have established a Community Advisory Panel (CAP). CAP members are voluntary, unpaid individuals from the Village of Hoosick Falls and Newburgh communities. The CAP for each community advises us on our study progress and communication of study progress and results, relays community questions and concerns, and encourages community outreach and participation. The CAPs are a critical partner in this study!

 

All CAP meetings are open to the public.

Resources

What are PFAS?
Per- and Polyfluorinated Substances (PFAS)

PFAS are a group of chemicals used to make coatings and products that can resist heat, water, oil, grease, and stains. These coatings can be found in many products, such as clothing, furniture, adhesives, food packaging, non-stick cooking surfaces, and electrical wire insulation. Many PFAS, including PFOS and PFOA, are a concern because they do not break down in the environment, they can contaminate drinking water, and they can buildup in fish and wildlife.

PFAS have been found in bodies of water and in many types of animals, both aquatic and on land.

PFAS Exposure

PFAS exposure can occur by consuming PFAS-contaminated water or food. Use of products containing PFAS may also lead to exposure. Common items with PFAS can include:

  • Food packaging: microwave popcorn, fast food wrappers, takeout containers
  • Household items: makeup, floss, waxes, paints, stains
  • Stain-resistant products: carpets, rugs, and furniture
  • Non-stick cookware, such as Teflon pans
  • Outdoor gear or clothing with water repellent coatings
  • Firefighting foams

How PFAS Affect Our Health

Human health effects from exposure to low levels of PFAS are uncertain. Studies in animals exposed to higher levels of PFAS indicate that some PFAS may affect growth and development, reproduction, thyroid function, immunity, and liver function. Studies on the effects of PFAS exposure can also be found under the Research tab. More research is necessary, however, to further assess the human health effects of exposure to varying levels of PFAS.

How is the Multi-site PFAS Health Study different from other blood testing programs conducted in the Newburgh and Hoosick Falls Area communities?

The purpose of the MSS PFAS Health Study was to learn more about PFAS levels and health effects in study participants from across the United States. Participants were asked to complete a health clinic visit that included health evaluations along with blood testing to explore if PFAS could be related to health outcomes. Data collected has been combined with those from other participants in California, Colorado, Massachusetts, Michigan, New Jersey, and Pennsylvania to create a larger study population. Other NYS Department of Health blood testing programs in the Newburgh and Hoosick Falls Area have focused on measuring PFAS levels in participants related to drinking water with PFOA or PFOS contamination.

Hoosick Falls Medical Monitoring Program

The Hoosick Falls Medical Monitoring Program is being conducted as part of the Hoosick Falls Settlement. Please visit the Hoosick Falls PFOA Settlement website for more information.

PFAS Biomonitoring

The NYSDOH Biomonitoring program measured how much PFAS you have been exposed to and compared PFAS blood levels in the village of Hoosick Falls and Hoosick area, and the City of Newburgh and to levels in the general population. If you would like to request a copy of your previous test results, please call NYSDOH at 518-402-7950.

ATSDR PFAS Exposure Assessment

The CDC and ATSDR assessed the PFAS exposure in communities near current or former military installations, including the City of Newburgh. For information on the findings, please visit ATSDR PFAS Exposure Assessment.
