Millions of Americans may be drinking water with unsafe levels of industrial chemicals, according to a study published Tuesday in the journal Environmental Science & Technology Letters. These chemicals, known as polyfluoroalkyl and perfluoroalkyl substances or PFASs, have been linked to high cholesterol, obesity, hormone suppression — and even cancer.
Introduced more than 60 years ago, PFASs are a category of man-made chemicals that degrade very slowly, if at all, in the environment.
“I do think that Americans should be concerned about these chemicals,” said Susan M. Pinney, a professor in the department of environmental health at University of Cincinnati. Pinney, who did not participate in the new research, explained that not enough time has elapsed to understand all the long-term health effects of these toxins.
