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|
|Methylmercury||low||Dietary sources, particularly seafood|
|Perfluorochemicals (PFCs)||low||Cancer, 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)
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  (14th %ile) (comparison based on congeners tested by CDC)
|0||ug/L (wet weight) in whole blood||25.9|
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)
|8.51||ng/g (wet weight) in blood serum||59.7|
Total Perfluorochemicals (PFCs)
Chemicals not found in Participant #2
