Line 1: {{~~Refimprove~~Ref improve\|date=February 2009}} A '''~~Polyhalogenated~~polyhalogenated ~~compounds~~compound''' (~~PHCs~~'''PHC''') ~~are~~is any ~~compounds~~compound with multiple substitutions of [[halogen]]s. 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. [[Polybrominated diphenyl ethers\|PBDE]]s, [[Polychlorinated biphenyl\|PCB]]s, [[Polychlorinated dibenzodioxins\|dioxins (PCDDs)]] and [[Perfluorinated compounds\|PFC]]s are all polyhalogenated compounds. They are generally non-[[miscible]] in organic solvents or water, but miscible in some [[hydrocarbons]] from which they often derive. ==Uses== PHCs are used in a vast array of manufactured products, from wood treatments, to cookware coatings, to non-stick, waterproof, and fire-resistant coatings, cosmetics, medicine, electronic fluids, food containers, and wrappings, in everything from [[furniture]] and furnishings, [[automobiles]], [[airplanes]], [[plastics]], [[clothing]] and cloth, surgery, insulation, adhesives, paints, sealants, lubricating oils, polyurethane foams, cancer therapy, and medical imaging. They are also heavily used in [[pest control]].▼ ~~PHCs are used in a vast array a~~ ▲manufactured products, from wood treatments, to cookware coatings, to non-stick, waterproof, and fire-resistant coatings, cosmetics, medicine, electronic fluids, food containers and wrappings, in everything from [[furniture]] and furnishings, [[automobiles]], [[airplanes]], [[plastics]], [[clothing]] and cloth, surgery, insulation, adhesives, paints, sealants, lubricating oils, polyurethane foams, cancer therapy and medical imaging.
