Polyhalogenated compounds (PHCs) are any compounds with multiple substitutions of halogens. They are of particular interest and importance because they bioaccumulate in humans, and comprise a superset of which has many toxic and carcinogenic industrial chemicals as members. PBDEs, PCBs, dioxins (PCDDs) and PFCs are all polyhalogenated compounds. They are generally non-miscible in organic solvents or water, but miscible in some hydrocarbons from which they often derive.
Despite bioaccumulating in humans, patents have been filed for removal of halogen by electrolysis[1] during manufacturing, though toxic chlorinated compounds may be created as byproducts of chlorinated compounds. Another method during manufacture is to use anaerobic bacteria [2]
