about this participant:

Participant #2, a journalist from Silver Spring, MD, participated in the 2006 biomonitoring investigation entitled "EWG Study #5, Teflon and mercury in blood in adults and teens." She gave blood for the study on November 17, 2004 at age 55.

Location:

Silver Spring, MD

Female, Adult

Study:

EWG Study #5, Teflon and mercury in blood in adults and teens

Sample Date:

November 17, 2004

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 endocrine system toxicity.

• This participant's samples show above average levels of PFHpA (Perfluoroheptanoic acid), compared to all others in EWG studies

Summary of chemicals found in Participant #2

Detailed report by chemical (return to summary)

perfluorochemicals (pfcs)

7 of 13 found

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)

8.51	ng/g (wet weight) in blood serum	59.7

PFDA (Perfluorodecanoic acid)

Breakdown product of stain- and grease-proof coatings on food packaging, couches, carpets. A 10-carbon version of PFOA; persistent; bioaccumulative.

• level found: 0.2 ng/g (wet weight) in blood serum
• Low vs 8 tested in EWG/Commonweal studies (13th %ile)

0.2	ng/g (wet weight) in blood serum	2.03

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: 0.095 ng/g (wet weight) in blood serum
• Moderate vs 8 tested in EWG/Commonweal studies (75th %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: 0.591 ng/g (wet weight) in blood serum
• Low vs 8 tested in EWG/Commonweal studies (13th %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: 2.92 ng/g (wet weight) in blood serum
• Low vs 8 tested in EWG/Commonweal studies (13th %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: 0.115 ng/g (wet weight) in blood serum
• Low vs 8 tested in EWG/Commonweal studies (13th %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: 0.633 ng/g (wet weight) in blood serum
• Low vs 8 tested in EWG/Commonweal studies (13th %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: 3.96 ng/g (wet weight) in blood serum
• Low vs 8 tested in EWG/Commonweal studies (13th %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: 0.106 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)

	ug/L (wet weight) in whole blood	25.9

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)
