Participant: Jessica Welborn
Found 27-29 of 70 tested chemicals
Jessica Welborn's blood and urine contained 27-29 of 70 industrial compounds, pollutants and other chemicals tested, including chemicals linked to reproductive toxicity and fertility problems, brain and nervous system toxicity, and immune system toxicity.
- This participant's samples show above average levels of Bisphenol A, BADGE-4OH, Polybrominated diphenyl ethers (PBDEs) and Methylmercury compared to all others in EWG studies

Test results by chemical family (see each chemical)
polybrominated diphenyl ethers (pbdes)
13-15 of 46 found — see each chemical
Fire retardants in furniture foam, computers, and televisions. Accumulate in human tissues. May harm brain development.
- cumulative level found: 26.3 ng/g (lipid weight) in blood serum
- Moderate vs 116 tested in EWG/Commonweal studies (58th %ile)
- Moderate vs 2,337 tested in CDC biomonitoring [1] (39th %ile) (comparison based on congeners tested by CDC)
1.11 | ng/g (lipid weight) in blood serum | 314 |

Total Polybrominated diphenyl ethers (PBDEs)
perfluorochemicals (pfcs)
3 of 13 found — see each chemical
Includes Teflon, Scotchgard, Stainmaster. Linked to cancer and birth defects.
- cumulative level found: 6.69 ng/mL (wet weight) in blood serum
- Low vs 55 tested in EWG/Commonweal studies (11th %ile)
- Low vs 3,959 tested in CDC biomonitoring [1] (9th %ile) (comparison based on congeners tested by CDC)

Total Perfluorochemicals (PFCs)
metals
2 of 2 found
Neurotoxic heavy metal linked to IQ deficits and behavioral problems. Found in dust from chipping lead paint in older homes, and in some tap water.
- level found: 1.6 ug/dL (wet weight) in whole blood
- Moderate vs 71 tested in EWG/Commonweal studies (44th %ile)
- Moderate vs 8,373 tested in CDC biomonitoring [1] (58th %ile) (comparison based on congeners tested by CDC)
0.222 | ug/dL (wet weight) in whole blood | 4.7 |
![]() |
Forms from mercury, a pollutant from coal-fired power plants and other sources. Methylmercury accumulates in seafood and harms brain development and function.

- Moderate vs 88 tested in EWG/Commonweal studies (52nd %ile)
- High vs 8,373 tested in CDC biomonitoring [1] (89th %ile) (comparison based on congeners tested by CDC)
ug/L (wet weight) in whole blood | 25.9 | |

bisphenol a & badge
2 of 2 found
Detected in polycarbonate plastic, dental sealants, and resins that line metal cans. Linked to hormone disruption, birth defects, cancer with effects at very low doses.
- level found: 2.61 ng/mL (wet weight) in blood serum
- High vs 51 tested in EWG/Commonweal studies (91st %ile)
ng/mL (wet weight) in blood serum | 8.61 | |
![]() |
Metabolite of BADGE, used to make metal food can linings. Linked to hormone activity, skin and immune system toxicity and cancer.
- level found: 28 ng/mL (wet weight) in blood serum
- High vs 41 tested in EWG/Commonweal studies (76th %ile)
ng/mL (wet weight) in blood serum | 174 | |
