Nora Pouillon's blood contained 9 of 14 industrial compounds, pollutants and other chemicals tested, including chemicals linked to cancer, birth defects and developmental delays, and endocrine system toxicity.

• This participant's samples show the highest levels of Perfluorochemicals (PFCs), PFDA (Perfluorodecanoic acid), PFDoA (Perfluorododecanoic acid), PFNA (Perfluorononanoic acid), PFOA (Perfluorooctanoic acid), PFUnA (Perfluoroundecanoic acid) compared to all others in EWG studies
• This participant's samples show above average levels of PFOS (Perfluorooctanesulfonate), Methylmercury, compared to all others in EWG studies

0.044	ng/g (wet weight) in blood serum	0.127

PFNA (Perfluorononanoic acid)

Breakdown product of stain- and grease-proof coatings on food packaging, couches, carpets. A 9-carbon version of PFOA; persistent; bioaccumulative.

• level found: 5.24 ng/g (wet weight) in blood serum
• High vs 8 tested in EWG/Commonweal studies (99th %ile)

0.591	ng/g (wet weight) in blood serum	5.24

PFOA (Perfluorooctanoic acid)

Used to make Teflon pan coatings; breakdown product of stain- and grease-proof coatings. Likely human carcinogen. Found in most people. Being phased out of some products.

• level found: 7.83 ng/g (wet weight) in blood serum
• High vs 8 tested in EWG/Commonweal studies (99th %ile)

2.92	ng/g (wet weight) in blood serum	7.83

PFUnA (Perfluoroundecanoic acid)

Breakdown product of stain- and grease-proof coatings on food packaging, couches, carpets. An 11-carbon version of PFOA; persistent; bioaccumulative.

• level found: 1.49 ng/g (wet weight) in blood serum
• High vs 8 tested in EWG/Commonweal studies (99th %ile)

0.115	ng/g (wet weight) in blood serum	1.49

PFHxS (Perfluorohexanesulfonate)

In fire fighting foams and carpet treatments. Phased out of consumer products by 3M in 2000 over health concerns.

• level found: 3.2 ng/g (wet weight) in blood serum
• High vs 8 tested in EWG/Commonweal studies (88th %ile)

0.633	ng/g (wet weight) in blood serum	3.5

PFOS (Perfluorooctanesulfonate)

Active ingredient in Scotchgard prior to 2000. Phase out forced by EPA because concentrations in human blood close to levels that harm lab animals.

• level found: 39.7 ng/g (wet weight) in blood serum
• High vs 8 tested in EWG/Commonweal studies (88th %ile)

3.96	ng/g (wet weight) in blood serum	47

metals

1 of 1 found

Methylmercury

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: 4.98 ug/L (wet weight) in whole blood
• Moderate vs 88 tested in EWG/Commonweal studies (72nd %ile)
• High vs 8,373 tested in CDC biomonitoring [1] (97th %ile)

	ug/L (wet weight) in whole blood	25.9

Chemicals not found in Nora Pouillon

5 chemicals

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