Halogenated aromatic compounds bioaccumulation

Synonyms Pentachloro(trichloroethenyl)-benzene Chemical/Pharmaceutical/Other Class Octachlorostyrene is a persistent, bioaccumulative, halogenated aromatic compound. Related compounds include other chlorinated styrenes that... 

Another entry point for accumulation of organic in animal tissue and animal food products is direct ingestion of contaminated soil by grazing animals [44]. The compounds of main concern are the halogenated aromatics, including PCBs, organochlorine pesticides, PCDDs and PCDFs, which are resistant to metabolization and tend to accumulate in animal fat. The bioaccumulation factor (the ratio of the concentration of animal tissue or produce to the concentration in the diet) can be as high as 5-6 [43]. Compounds such as PAHs and phthalate esters are readily metabolised and excreted by the animals and thus do not accumulate in animal tissue or products.
