Participant: Landon Gellert
Found 30-33 of 70 tested chemicals
Landon Gellert's blood and urine contained 30-33 of 70 industrial compounds, pollutants and other chemicals tested, including chemicals linked to reproductive toxicity and fertility problems, brain and nervous system toxicity, and immune system toxicity.
- This participant's samples show above average levels of Perfluorochemicals (PFCs), Methylmercury, compared to all others in EWG studies

Test results by chemical family (see each chemical)
1 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: 9.31 ng/mL (wet weight) in blood serum
- Moderate vs 41 tested in EWG/Commonweal studies (47th %ile)
|0||ng/mL (wet weight) in blood serum||174|
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: 1.3 ug/dL (wet weight) in whole blood
- Moderate vs 71 tested in EWG/Commonweal studies (37th %ile)
- Moderate vs 8,373 tested in CDC biomonitoring  (46th %ile) (comparison based on congeners tested by CDC)
|0.222||ug/dL (wet weight) in whole blood||4.7|
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: 2.42 ug/L (wet weight) in whole blood
- Moderate vs 88 tested in EWG/Commonweal studies (54th %ile)
- High vs 8,373 tested in CDC biomonitoring  (90th %ile) (comparison based on congeners tested by CDC)
|0||ug/L (wet weight) in whole blood||25.9|
5 of 13 found — see each chemical
Includes Teflon, Scotchgard, Stainmaster. Linked to cancer and birth defects.
- cumulative level found: 43.5 ng/mL (wet weight) in blood serum
- High vs 55 tested in EWG/Commonweal studies (84th %ile)
- High vs 3,959 tested in CDC biomonitoring  (76th %ile) (comparison based on congeners tested by CDC)
|2.63||ng/mL (wet weight) in blood serum||77.7|
Total Perfluorochemicals (PFCs)
5 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: 119 ug/g creatinine in urine
- Low vs 72 tested in EWG/Commonweal studies (7th %ile)
- Low vs 8,020 tested in CDC biomonitoring  (16th %ile) (comparison based on congeners tested by CDC)
|102||ug/g creatinine in urine||10800|
17-20 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: 8.29 ng/g (lipid weight) in blood serum
- Low vs 116 tested in EWG/Commonweal studies (17th %ile)
- Low vs 2,337 tested in CDC biomonitoring  (16th %ile) (comparison based on congeners tested by CDC)
|1.11||ng/g (lipid weight) in blood serum||314|
Total Polybrominated diphenyl ethers (PBDEs)
