"The Trump administration has approved three new pesticides that may be considered “forever chemicals” under an international definition, though the Environmental Protection Agency (EPA)  is disputing the characterization.

This week, the EPA approved pesticides that contain molecules with carbon-fluorine bonds, which can be very strong and therefore difficult to break down over time.

“They’re all breaking down into things that are going to stick around forever,” said Nathan Donley, environmental health science director at the Center for Biological Diversity. 

He added that the chemicals are considered “forever chemicals” under a definition put forward by the Organization for Economic Cooperation and Development (OECD)."
