Participant: Michael Goodstein
Found 8 of 14 tested chemicals

Michael Goodstein's blood contained 8 of 14 industrial compounds, pollutants and other chemicals tested, including chemicals linked to cancer, birth defects and developmental delays, and endocrine system toxicity.

  • Mercury exposure above the federal government's safe level
  • This participant's samples show above average levels of Methylmercury, Perfluorochemicals (PFCs), compared to all others in EWG studies

perfluorochemicals (pfcs)

7 of 13 found — see each chemical

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

  • cumulative level found: 38.4 ng/g (wet weight) in blood serum
  • Moderate vs 8 tested in EWG/Commonweal studies (75th %ile)
8.51ng/g (wet weight) in blood serum59.7

Total Perfluorochemicals (PFCs)


1 of 1 found

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: 5.99 ug/L (wet weight) in whole blood [A]
  • High vs 88 tested in EWG/Commonweal studies (79th %ile)
  • High vs 8,373 tested in CDC biomonitoring [1] (98th %ile) (comparison based on congeners tested by CDC)
ug/L (wet weight) in whole blood25.9

Chemicals not found in Michael Goodstein

6 chemicals
