Regrettable Substitutions

In an eye-opening report, Sharon Lerner describes how DuPont concealed the dangers of a chemical created to replace the chemical known as C8 used to make Teflon—a case of what environmentalists term “regrettable substitutions.”

After lawsuits revealed a cancer link with C8 (perfluorooctanoic acid), DuPont agreed to phase it out. But evidence collected by EPA investigators along the Cape Fear River in North Carolina suggests similar composition, toxicity and environmental persistence among its replacements.

Bills currently before Congress fail to address two key issues: requiring companies to submit specific safety data before new chemicals are approved for use, and trade secret provisions that protect companies at safety’s expense.
