Layman's explanation:
1,2-Dichloronaphthalene is a PCN (polychlorinated naphthalenes) which is synthesized in a mixture of several congeners, ranging from thin liquids to hard waxes to high melting point solids. PCNs have been used as waxes and impregnants (for protective coatings), water repellents, and wood preservatives. The major sources of release of chlorinated naphthalenes into the environment are likely to be from waste incineration and disposal of items containing chlorinated naphthalenes to landfill. PCNs are no longer produced due to their toxicity. Like related compounds (such as PCBs), chlorinated naphthalenes have been demonstrated to be inducers of the cytochrome P-450 (CYP) dependent microsomal enzymes. The environmental impact of PCNs has not been extensively investigated, and PCN concentrations have only been measured in the environment in a few rare cases. Chlorinated naphthalenes are expected to adsorb onto soil and sediments to a large extent, and have been identified to do as such in drainage ditches and sediments from Florida and the San Francisco bay. PCNs have also been identified in birds of prey in Britain and the Netherlands.
