Participant: Participant #2
Found 8 of 14 tested chemicals

Participant #2's blood contained 8 of 14 industrial compounds, pollutants and other chemicals tested, including chemicals linked to cancer, birth defects and developmental delays, and behavioral effects.

Summary of chemicals found in Participant #2

chemical family level found health effects exposure routes
Methylmercurylow Dietary sources, particularly seafood
Perfluorochemicals (PFCs)lowCancer, Birth defects and developmental delays, Endocrine system Stain- and grease-proof coatings on food packaging, couches, carpets, pans

Test results by chemical family (see each chemical)

metals

1 of 1 found

Forms from mercury, a pollutant from coal-fired power plants and other sources. Methylmercury accumulates in seafood and harms brain development and function.

  • level found: 0.106 ug/L (wet weight) in whole blood
  • Low vs 88 tested in EWG/Commonweal studies (7th %ile)
  • Low vs 8,373 tested in CDC biomonitoring [1] (14th %ile) (comparison based on congeners tested by CDC)
0ug/L (wet weight) in whole blood25.9


perfluorochemicals (pfcs)

7 of 13 found — see each chemical

Includes Teflon, Scotchgard, Stainmaster. Linked to cancer and birth defects.

  • cumulative level found: 8.51 ng/g (wet weight) in blood serum
  • Low vs 8 tested in EWG/Commonweal studies (13th %ile)
8.51ng/g (wet weight) in blood serum59.7


Total Perfluorochemicals (PFCs)

Chemicals not found in Participant #2

6 chemicals

PFBS (Perfluorobutane sulfonate), PFDoA (Perfluorododecanoic acid), PFHxA (Perfluorohexanoic acid), PFPeA (Perfluoro-n-pentanoic acid), PFTA (Perfluorotetradecanoic acid), PFBA (Perfluorobutyric acid)
