The Environmental Protection Agency said Wednesday that GenX is less toxic than the chemical it replaced, but exposure could carry a risk of cancer.
The EPA released a draft toxicity assessment of GenX and another compound. A statement related to the assessment said animal studies on GenX especially showed effects on the liver following oral exposure. Other health effects were in the kidney, blood, immune system and developing fetus, it said.
“The data are suggestive of cancer,” the statement said.
GenX is manufactured at the Chemours plant in Bladen County near the Cumberland County line. The compound also is a byproduct of other processes there.
GenX, which is used to make nonstick cookware and other products, has been found in hundreds of private wells around the Chemours facility and in lakes and creeks nearby. It replaced PFOA, which also is known as C8 because it has eight carbon atoms.
The EPA’s draft toxicity assessment lists a draft reference dose for GenX of .00008 milligrams daily per each kilogram of weight. That’s four times the dose for PFOA and PFOS, a similar compound, according to the assessment.
The reference dose estimates how much of a chemical a person could ingest daily over a lifetime without the likelihood of adverse health effects, according to Enesta Jones, an EPA spokeswoman. The dose is only a part of the risk assessment for a compound and is not directly comparable to the measurement of parts per trillion, she said.
