(5Z)-5-pyrrol-2-ylidene-1,2-dihydrotetrazole manufacturer Unfortunately, PFAS are considered forever chemicals” because they don’t naturally degrade, Bruton said. Instead, they accumulate in the bodies of humans and animals. It’s believed that every single American has a detectable level of PFAS in their bodies.
Some PFAS chemicals have been shown to be toxic, potentially contributing to high cholesterol levels, low infant birth weights, immune deficiencies and thyroid gland disruptions, according to the EPA.
“The problem with these chemicals is they last a long time in the environment as well as in your body,” said Dr. Maaike van Gerwen, an assistant professor in the Institute of Translational Epidemiology at Mount Sinai in New York City. “We do not know exactly what the harm is of exposure to very low levels of these chemicals over a very long period of time, because these are a relatively new kind of chemical.
