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: 29.9 ng/g (lipid weight) in blood serum
  • Moderate vs 116 tested in EWG/Commonweal studies (63rd %ile)
  • Moderate vs 2,337 tested in CDC biomonitoring [1] (43rd %ile) (comparison based on congeners tested by CDC)
1.11ng/g (lipid weight) in blood serum314

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: 129 ng/mL (wet weight) in blood serum
  • High vs 41 tested in EWG/Commonweal studies (93rd %ile)
ng/mL (wet weight) in blood serum174


6 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: 210 ug/g creatinine in urine
  • Moderate vs 72 tested in EWG/Commonweal studies (32nd %ile)
  • Moderate vs 8,020 tested in CDC biomonitoring [1] (36th %ile) (comparison based on congeners tested by CDC)

4 of 13 found — see each chemical

Includes Teflon, Scotchgard, Stainmaster. Linked to cancer and birth defects.

  • cumulative level found: 46 ng/mL (wet weight) in blood serum

Total Perfluorochemicals (PFCs)


2 of 2 found

Forms from mercury, a pollutant from coal-fired power plants and other sources. Methylmercury accumulates in seafood and harms brain development and function.

  • Low vs 88 tested in EWG/Commonweal studies (6th %ile)
  • Low vs 8,373 tested in CDC biomonitoring [1] (14th %ile) (comparison based on congeners tested by CDC)
ug/L (wet weight) in whole blood25.9

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: 2.7 ug/dL (wet weight) in whole blood
  • Moderate vs 71 tested in EWG/Commonweal studies (74th %ile)
