The never-ending story: Chemicals that outlive—and harm—us

 "The researchers from Sweden, Switzerland, and the United States call for regulation of the entire class of highly fluorinated chemicals ( polyfluoroalkyl substances ). Exposure to the most well-studied of these substances has been linked to kidney and testicular cancer, elevated cholesterol, decreased fertility, thyroid problems and changes in hormone functioning in adults as well as adverse developmental effects and decreased immune response in children.
This class of chemicals does not break down—ever—and can remain in the environment for thousands of years. "I am concerned that researchers and regulators are continuing to focus on a few phased-out chemicals rather than the thousands of related substances in use today," said Dr. Ian Cousins, co-author of the paper and Professor at Stockholm University. "Unless we broaden our focus, future generations will be increasingly exposed via contaminated water, air, and food.""
