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.

  • geometric mean: 5.29 ng/mL in blood serum (vs. 9.33 in all EWG/Commonweal studies)
  • found in 1 of 2 people in the group (vs. 30 of 41 in all EWG/Commonweal studies)
  • found in: Jessica Welborn
3.02ng/mL 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.

  • geometric mean: 1.62 ng/mL in blood serum (vs. 0.456 in all EWG/Commonweal studies)
  • found in 1 of 2 people in the group (vs. 16 of 51 in all EWG/Commonweal studies)
  • found in: Jessica Welborn
0.445ng/mL 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.

  • geometric mean: 2.19 ug/dL in whole blood (vs. 1.33 in CDC biomonitoring [1])
  • found in 2 of 2 people in the group (vs. 7,896 of 8,373 in CDC biomonitoring)
  • found in: Jessica Welborn, Ann Hunter-Welborn
0.222ug/dL 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.

  • geometric mean: 3.38 ug/L in whole blood (vs. 0.56 in CDC biomonitoring [1])
  • found in 2 of 2 people in the group (vs. 7,584 of 8,373 in CDC biomonitoring)
  • found in: Jessica Welborn, Ann Hunter-Welborn
0.0735ug/L in whole blood25.9


perfluorochemicals (pfcs)

4 of 13 found — see each chemical

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

  • geometric mean: 10.2 ng/mL in blood serum (vs. 22.7 in CDC biomonitoring [1])
  • found in 2 of 2 people in the group (vs. 3,684 of 3,959 in CDC biomonitoring)
  • found in: Jessica Welborn, Ann Hunter-Welborn
2.63ng/mL 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.

  • geometric mean: 237 ug/g creatinine in urine (vs. 315 in CDC biomonitoring [1])
  • found in 2 of 2 people in the group (vs. 7,928 of 8,020 in CDC biomonitoring)
  • found in: Jessica Welborn, Ann Hunter-Welborn
102ug/g creatinine in urine10800


Total Phthalates

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.

  • geometric mean: 32.9 ng/g lipids in blood serum (vs. 26.3 in CDC biomonitoring [1])
      [excludes PBDE-154/PBB-153]
  • found in 2 of 2 people in the group (vs. 2,037 of 2,337 in CDC biomonitoring)
  • found in: Jessica Welborn, Ann Hunter-Welborn
1.11ng/g lipids in blood serum314


Total Polybrominated diphenyl ethers (PBDEs)
