==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]].
==Safety==
PHCs include notoriously dangerous substances, including [[Agent Orange]], [[DDT]], and other [[pesticides]]. Many non-pesticide PHCs have the same safety issues as pesticides.
==Types==
* Polycholorinated, e.g. [[Polychlorinated biphenyl|PCB]]s, [[polychlorinated dibenzodioxins|dioxins]] (PCDDs), [[hexachlorophene]], [[dibenzofurans]] (PCDFs), [[polychloro phenoxy phenol]]s (PCPPs), [[polychlorinated diphenyl ethers]] (PCDEs).
* Polybrominated, e.g., [[PBDE]]s, [[polybrominated biphenyls]] (PBBs).
* [[Perfluorinated compounds]]
* Polyiodinated compounds
==Breakdown of compounds==
Despite bioaccumulating in humans, it has been claimed that a method during manufacture using anaerobic bacteria may be efficacious <ref>{{Cite journal |doi = 10.1038/368627a0|pmid = 8145847|title = Metabolism of polyhalogenated compounds by a genetically engineered bacterium|journal = Nature|volume = 368|issue = 6472|pages = 627–629|year = 1994|last1 = Wackett|first1 = Lawrence P.|last2 = Sadowsky|first2 = Michael J.|last3 = Newman|first3 = Lisa M.|last4 = Hur|first4 = Hor-Gil|last5 = Li|first5 = Shuying|bibcode = 1994Natur.368..627W|s2cid = 4315658}}</ref>
