Scientists from North Carolina have found some pretty shocking information about PFAS, better known as “forever chemicals,” in blood samples. This recent research indicates that these substances might be gathering in our bodies in ways we didn’t expect.
What’s the Buzz?
A recent study published in Environmental Science and Technology analyzed blood samples from Wilmington residents collected between 2010 and 2016. To their surprise, researchers found elevated levels of ultrashort-chain PFAS—specifically perfluoromethoxyacetic acid (PFMOAA) and trifluoroacetic acid (TFA)—in a vast majority of the samples.
These chemicals are thought to have originated from the Chemours Fayetteville Works chemical plant, which has consistently released PFAS into the Cape Fear River, Wilmington’s key drinking water source, for many years. Interestingly, while GenX stirred up outrage in the area and showed up in about 20% of samples, both PFMOAA and TFA were found much more frequently—with PFMOAA hitting alarming median levels of 42 nanograms per milliliter.
As Jane Hoppin, one of the study’s authors, noted, “Conventional wisdom suggests that short-chain PFAS are not as concerning because they don’t accumulate in our bodies. However, the data indicates otherwise, showing high levels present in individuals.”
Why This Matters
PFAS, a group of chemicals often used in products such as non-stick cookware, water-repellent clothing, and firefighting foam, are tied to numerous health concerns. These range from higher risks for infections and liver or thyroid diseases to fertility issues and cancers.
Scientists had previously thought shorter PFAS chains were less likely to build up in human biology compared to longer chains like GenX. Thanks to recent advances, they are now able to detect these compounds in our blood, leading to new questions about their health implications.
Hoppin mentioned, “The sample we analyzed offers a snapshot into the past, and knowing the current levels can aid us in understanding how these chemicals accumulate and the potential health risks involved.”
What Steps Are Being Taken?
Since 2017, the Fayetteville Works facility has been mandated to reduce PFAS discharges into local water and air. However, it’s possible that the damage may have already extended far and wide. Researchers are looking to expand the GenX Exposure Study with fresh samples to better comprehend the effects of these contaminants.
In the meantime, measures to tackle PFAS pollution are increasing. As federal regulations regarding these substances in drinking water remain uncertain, many states are implementing stricter limits to safeguard drinking supplies.
For individuals, experts suggest using a water filter that can effectively remove PFAS, like those based on activated carbon or high-pressure membranes. Additionally, it’s wise to steer clear of non-stick cookware and any fabrics treated with PFAS.
