WebFeb 1, 2009 · Chlorinated polycyclic aromatic hydrocarbons (CIPAHs) are a class of halogenated contaminants found in the urban atmosphere; they have toxic potential similar to that of dioxins. Information on the sources of CIPAHs is limited. Chlorinated polycyclic aromatic hydrocarbons are generated by combustion of organic compounds. Cl-PAHs enter the environment from a multiplicity of sources and tend to persist in soil and in particulate matter in air. Environmental data and emission sources analysis for Cl-PAHs reveal that the dominant … See more Chlorinated polycyclic aromatic hydrocarbons (Cl-PAHs) are a group of compounds comprising polycyclic aromatic hydrocarbons with two or more aromatic rings and one or more chlorine atoms attached to the ring … See more One of the well-established mechanisms by which chlorinated polycyclic aromatic hydrocarbons can exert their toxic effects is via the function of the aryl hydrocarbon receptor (AhR). The AhR-mediated activities of Cl-PAHs have been determined by … See more Some Cl-PAHs have structural similarities to dioxins, they are suspected of having similar toxicities. These types of compounds are known to be carcinogenic, mutagenic, and teratogenic. Toxicological studies have shown that some Cl-PAHs possess greater … See more
