Detailed report by chemical (return to summary)

metals

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: 1.17 ug/L (wet weight) in whole blood
  • Moderate vs 88 tested in EWG/Commonweal studies (40th %ile)
  • Moderate vs 8,373 tested in CDC biomonitoring [1] (71st %ile)
0ug/L (wet weight) in whole blood25.9


perfluorochemicals (pfcs)

8 of 13 found

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

  • cumulative level found: 23.4 ng/g (wet weight) in blood serum
  • Moderate vs 8 tested in EWG/Commonweal studies (50th %ile)
8.51ng/g (wet weight) in blood serum59.7


Total Perfluorochemicals (PFCs)

Breakdown product of stain- and grease-proof coatings on food packaging, couches, carpets. A 10-carbon version of PFOA; persistent; bioaccumulative.

  • level found: 0.403 ng/g (wet weight) in blood serum
  • Moderate vs 8 tested in EWG/Commonweal studies (38th %ile)
0.2ng/g (wet weight) in blood serum2.03


Breakdown product of stain- and grease-proof coatings on food packaging, couches, carpets, including Stainmaster. Highly persistent and bioaccumulative.

  • level found: 0.111 ng/g (wet weight) in blood serum
  • High vs 8 tested in EWG/Commonweal studies (88th %ile)
0ng/g (wet weight) in blood serum0.168


Breakdown product of stain- and grease-proof coatings on food packaging, couches, carpets. A 7-carbon version of PFOA; persistent.

  • level found: 0.093 ng/g (wet weight) in blood serum
  • Moderate vs 8 tested in EWG/Commonweal studies (63rd %ile)
0.044ng/g (wet weight) in blood serum0.127


Breakdown product of stain- and grease-proof coatings on food packaging, couches, carpets. A 9-carbon version of PFOA; persistent; bioaccumulative.

  • level found: 1.02 ng/g (wet weight) in blood serum
  • Low vs 8 tested in EWG/Commonweal studies (25th %ile)
0.591ng/g (wet weight) in blood serum5.24


Used to make Teflon pan coatings; breakdown product of stain- and grease-proof coatings. Likely human carcinogen. Found in most people. Being phased out of some products.

  • level found: 4.89 ng/g (wet weight) in blood serum
  • Moderate vs 8 tested in EWG/Commonweal studies (75th %ile)
2.92ng/g (wet weight) in blood serum7.83


Breakdown product of stain- and grease-proof coatings on food packaging, couches, carpets. An 11-carbon version of PFOA; persistent; bioaccumulative.

  • level found: 0.699 ng/g (wet weight) in blood serum
  • Moderate vs 8 tested in EWG/Commonweal studies (63rd %ile)
0.115ng/g (wet weight) in blood serum1.49


In fire fighting foams and carpet treatments. Phased out of consumer products by 3M in 2000 over health concerns.

  • level found: 2.52 ng/g (wet weight) in blood serum
  • Moderate vs 8 tested in EWG/Commonweal studies (75th %ile)
0.633ng/g (wet weight) in blood serum3.5


Active ingredient in Scotchgard prior to 2000. Phase out forced by EPA because concentrations in human blood close to levels that harm lab animals.

  • level found: 13.7 ng/g (wet weight) in blood serum
  • Moderate vs 8 tested in EWG/Commonweal studies (38th %ile)
3.96ng/g (wet weight) in blood serum47
