  Dioxins & PCBs

Dioxins, a collective term for a group of environmental contaminants 
that includes certain dioxin, furan, and dioxin-like PCB 
(polychlorinated biphenyl) congeners, are found throughout the world.  
Dioxins and furans are released into the air from combustion processes. 
The wide use of PCBs as dielectric and coolant fluids in the past has 
resulted in thier presence in the environment. FDA has has been 
monitoring specific foods with the goal of identifying ways to reduce 
dietary exposure to dioxin.
