Participant: Martha Davis
Found 38-42 of 70 tested chemicals
Martha Davis's blood and urine contained 38-42 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.
- Mercury exposure above the federal government's safe level
- This participant's samples show above average levels of BADGE-4OH, Methylmercury, Lead and Polybrominated diphenyl ethers (PBDEs) compared to all others in EWG studies

Test results by chemical family (see each chemical)
polybrominated diphenyl ethers (pbdes)
22-26 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: 33.9 ng/g (lipid weight) in blood serum
- Moderate vs 116 tested in EWG/Commonweal studies (69th %ile)
- Moderate vs 2,337 tested in CDC biomonitoring [1] (48th %ile) (comparison based on congeners tested by CDC)
| 1.11 | ng/g (lipid weight) in blood serum | 314 |

Total Polybrominated diphenyl ethers (PBDEs)
bisphenol a & badge
1 of 2 found
Metabolite of BADGE, used to make metal food can linings. Linked to hormone activity, skin and immune system toxicity and cancer.
- level found: 135 ng/mL (wet weight) in blood serum
- High vs 41 tested in EWG/Commonweal studies (96th %ile)
| ng/mL (wet weight) in blood serum | 174 | |

perfluorochemicals (pfcs)
6 of 13 found — see each chemical
Includes Teflon, Scotchgard, Stainmaster. Linked to cancer and birth defects.
- cumulative level found: 22.8 ng/mL (wet weight) in blood serum
- Moderate vs 55 tested in EWG/Commonweal studies (40th %ile)
- Moderate vs 3,959 tested in CDC biomonitoring [1] (34th %ile) (comparison based on congeners tested by CDC)
| 2.63 | ng/mL (wet weight) in blood serum | 77.7 |

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: 3.6 ug/dL (wet weight) in whole blood
- High vs 71 tested in EWG/Commonweal studies (91st %ile)
- High vs 8,373 tested in CDC biomonitoring [1] (91st %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.
- level found: 8.72 ug/L (wet weight) in whole blood
- High vs 88 tested in EWG/Commonweal studies (93rd %ile)
- High vs 8,373 tested in CDC biomonitoring [1] (99th %ile) (comparison based on congeners tested by CDC)
| ug/L (wet weight) in whole blood | 25.9 | |

phthalates
7 of 7 found — see each chemical
In cosmetics, paint, and plastics. Linked to sperm damage and birth defects of male reproductive system.
- cumulative level found: 372 ug/g creatinine in urine
- Moderate vs 72 tested in EWG/Commonweal studies (57th %ile)
- Moderate vs 8,020 tested in CDC biomonitoring [1] (60th %ile) (comparison based on congeners tested by CDC)
| 102 | ug/g creatinine in urine | 10800 |
