Test results by chemical family (see each chemical)

bisphenol a & badge

2 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: 28 ng/mL (wet weight) in blood serum
  • High vs 41 tested in EWG/Commonweal studies (76th %ile)
0ng/mL (wet weight) in blood serum174


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)
0ng/mL (wet weight) in blood serum8.61


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)
0.222ug/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.

  • level found: 2.31 ug/L (wet weight) in whole blood
  • 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)
0ug/L (wet weight) in whole blood25.9


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)
2.63ng/mL (wet weight) in blood serum77.7


Total Perfluorochemicals (PFCs)

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: 150 ug/g creatinine in urine
  • Low vs 72 tested in EWG/Commonweal studies (14th %ile)
  • Low vs 8,020 tested in CDC biomonitoring [1] (23rd %ile) (comparison based on congeners tested by CDC)
102ug/g creatinine in urine10800


Total Phthalates

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)
1.11ng/g (lipid weight) in blood serum314


Total Polybrominated diphenyl ethers (PBDEs)
