Test results by chemical family (see each chemical)

polybrominated diphenyl ethers (pbdes)

19-21 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: 41.1 ng/g (lipid weight) in blood serum
  • Moderate vs 116 tested in EWG/Commonweal studies (72nd %ile)
  • Moderate vs 2,337 tested in CDC biomonitoring [1] (54th %ile) (comparison based on congeners tested by CDC)

Total Polybrominated diphenyl ethers (PBDEs)

perfluorochemicals (pfcs)

4 of 13 found — see each chemical

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

  • cumulative level found: 15.4 ng/mL (wet weight) in blood serum
  • Low vs 55 tested in EWG/Commonweal studies (22nd %ile)
  • Low vs 3,959 tested in CDC biomonitoring [1] (18th %ile) (comparison based on congeners tested by CDC)

Total Perfluorochemicals (PFCs)


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 ug/dL (wet weight) in whole blood
  • High vs 71 tested in EWG/Commonweal studies (82nd %ile)
  • High vs 8,373 tested in CDC biomonitoring [1] (86th %ile) (comparison based on congeners tested by CDC)
0.222ug/dL (wet weight) in whole blood4.7

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 (71st %ile)
  • High vs 8,373 tested in CDC biomonitoring [1] (97th %ile) (comparison based on congeners tested by CDC)
ug/L (wet weight) in whole blood25.9


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: 376 ug/g creatinine in urine
