Participant: Kelsey Wirth
Found 9 of 14 tested chemicals
Kelsey Wirth's blood contained 9 of 14 industrial compounds, pollutants and other chemicals tested, including chemicals linked to cancer, birth defects and developmental delays, and behavioral effects.
- This participant's samples show above average levels of Methylmercury, compared to all others in EWG studies
Summary of chemicals found in Kelsey Wirth
|chemical family||level found||health effects||exposure routes|
|Methylmercury||moderate||Dietary sources, particularly seafood|
|Perfluorochemicals (PFCs)||moderate||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: 1.17 ug/L (wet weight) in whole blood
- Moderate vs 88 tested in EWG/Commonweal studies (40th %ile)
- Moderate vs 8,373 tested in CDC biomonitoring  (71st %ile) (comparison based on congeners tested by CDC)
|0||ug/L (wet weight) in whole blood||25.9|
8 of 13 found — see each chemical
Includes Teflon, Scotchgard, Stainmaster. Linked to cancer and birth defects.
- cumulative level found: 23.4 ng/g (wet weight) in blood serum
- Moderate vs 8 tested in EWG/Commonweal studies (50th %ile)
|8.51||ng/g (wet weight) in blood serum||59.7|
