2019 Great Bay Deer Hunt PFAS Testing

Why did we test deer for PFAS Chemicals?

 

Per- and Polyfluoroalkyl Substance (PFAS) contamination is a regional health concern. Pease Development Authority, a known PFAS contaminated site, is in close proximity to the Great Bay National Wildlife Refuge, where an annual 2 day deer hunt has historically taken place.  Therefore, deer taken during the annual Great Bay hunt constitute an informative sample source for the assessment of PFAS in the local deer population.

 

What are PFAS chemicals?
(Info obtained from EPA website)


These substances are a group of synthetic chemicals that have been in use since the 1940s. PFAS are found in a wide array of consumer and industrial products. Airports and military installations where PFAS products were tested and used for firefighting are potential contributors of PFAS releases into the air, soil, and water. Due to their widespread use and persistence in the environment, most people in the United States have been exposed to PFAS. There is evidence that continued exposure above specific levels to certain PFAS may lead to adverse health effects.

 

 

What did we find?

 

During the 2019 Great Bay Deer Hunt, successful hunters were asked to provide muscle and liver tissue samples from their harvested deer for PFAS testing.  US Fish and Wildlife Service staff assisted in collecting tissue samples for the Department during the registration process. These samples were then sent to a lab at the University of Connecticut to screen for PFAS chemicals.  Sixteen (16) deer were sampled, yielding 16 muscle samples and 15 liver samples for a total of 31 tissue samples collected and tested. Each sample was tested for 14 PFAS compounds with the following results:

 

  • PFOS was the only PFAS chemical detected in any of the 31 tissue samples.
  • 3 of 15 liver samples (20%) were positive for PFOS, 80% of liver samples were negative for PFOS.
  • 15 liver samples (100%) were negative for any of the other 13 PFAS compounds tested.
  • 16 muscle samples (100%) were negative for any of 14 PFAS compounds tested.

 

No PFAS chemicals were detected in any of the muscle tissue samples tested, suggesting venison consumption likely represents a low risk for PFAS exposure.  While PFAS levels detected in deer livers were considered moderately low, the Department still recommends hunters do not consume deer liver. The liver is a filtering organ and therefore has potential to have high levels of a number of contaminants.
