Further concern over perfluorinated chemicals

Thermal degradation products found to be persistent, contribute to ozone depletion, global warming

Canadian researchers have found that widely used fluorinated polymers can break down to produce chemicals that are persistent or which damage the ozone layer or contribute to global warming. Reported in today's edition of the science journal, Nature, the findings add to growing international concern over fluoropolymers.

Fluoropolymers are used in a range of applications, from polytetrafluoroethylene (PTFE) to some engineering plastics, and Teflon, the non-stick material used in frying pans. Global consumption is thought to be rising fast.
