PFHpA (Perfluoroheptanoic acid)

Breakdown product of stain- and grease-proof coatings on food packaging, couches, carpets. A 7-carbon version of PFOA; persistent.

• level found: 0.058 ng/g (wet weight) in blood serum
• Low vs 8 tested in EWG/Commonweal studies (25th %ile)

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: 1.29 ng/g (wet weight) in blood serum
• Moderate vs 8 tested in EWG/Commonweal studies (38th %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: 3.07 ng/g (wet weight) in blood serum
• Low vs 8 tested in EWG/Commonweal studies (25th %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: 0.363 ng/g (wet weight) in blood serum
• Low vs 8 tested in EWG/Commonweal studies (25th %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: 1.3 ng/g (wet weight) in blood serum
• Moderate vs 8 tested in EWG/Commonweal studies (38th %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: 12.3 ng/g (wet weight) in blood serum
• Low vs 8 tested in EWG/Commonweal studies (25th %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: 0.636 ug/L (wet weight) in whole blood
• Moderate vs 88 tested in EWG/Commonweal studies (29th %ile)
• Moderate vs 8,373 tested in CDC biomonitoring [1] (50th %ile)

	ug/L (wet weight) in whole blood	25.9
