“…Birds, to the contrary, show a very efficient biotransformation of pp'-DDT, p,p′-DDD and their o,p′ isomers, with a selective high bioaccumulation of p,p′-DDE. Very slow decreasing trends were observed for p,p′-DDE over a 1971-2001 time interval (16% for year) by Jörundsdóttir et al (2006). The same authors found in guillemot (Uria aalge) eggs MeSO 2 -derivatives of DDTs and PCBs that are even more persistent than the parent compound and highly accumulable as well because of their lipophilicity (only slightly lower than the parent compound) and because of their ability to bind specifically to proteins.…”

Fish and piscivorous bird eggs collected in 2003 from Lake Maggiore (Italy), were analysed for PCB and DDT contamination. Lake Maggiore has been severely polluted by DDT through production of the pesticide within its catchment. Although agricultural application of DDT was banned in Italy in the 1978, industrial production continued until 1996, with enough contamination of water and soil for serious bioaccumulation in the lake biota. PCB and DDT concentrations in a whitefish (Coregonus macrophthalmus Nusslin 1882) were seen to be dependent on season and fish age, but not on sex. The average increase of the lipid-normalised concentration of DDTs and PCBs was two-fold across season and also across age, resulting in an overall increase of four fold. The seasonal variation was related to the ecophysiological cycle of the fish and to the contamination dynamic of the lake, while the effect of the fish age was explained on the base of biomagnificationrelated mechanisms. A fugacity model was applied to predict the age-dependent bioaccumulation potential of PCBs, whose concentrations were rather stable in recent years in the lake. Predicted values for compounds with negligible biotransformation were in good agreement with experimental data (calculated vs. experimental mean difference of 14%), and a relationship between the increase of experimental agedependent concentration and K ow was observed. The good correspondence between the predicted and the measured values for most PCB congeners confirmed the general inability of fishes to biotransform these compounds. On the contrary, the importance of biotransformation processes was recognised in birds; eggs of a fish eating bird (Podiceps cristatus) from the same area selectively bioaccumulated p,p′-DDE. For PCBs, congener 149 appears to be completely metabolized by the bird species, and congeners 95, 101, 132, 151 and 174 were reduced as well. The role of the meta-para free position on at least one phenyl ring of PCB congeners in biotransformation processes was confirmed.

“…Only non-coplanar PCBs with three or four ortho -chlorine substituents possess sufficient torsional strain to facilitate the formation of stable atropisomer pairs that can be separated chromatographically (Kaiser, 1974, Norstrom et al, 2006, Haglund, 1996). PCBs 84, 91, 95, 132, 136, 149, 174 and/ or their metabolites have been shown to accumulate enantioselectively in mammalian tissues (Lehmler et al, 2010), in birds (Jörundsdottir et al, 2006), in plants (Zhai et al, 2011) and in humans (Ellerichmann et al, 1998, Hovander et al, 2004). …”

The metabolism of polychlorinated biphenyls (PCBs) is complex and has an impact on toxicity and thereby assessment of PCB risks. A large number of reactive and stable metabolites are formed in the processes of biotransformation in biota in general and in humans in particular. The aim of this document is to provide an overview of PCB metabolism and to identify metabolites of concern and their occurrence. Emphasis is given to mammalian metabolism of PCBs and their hydroxyl, methylsulfonyl, and sulfated metabolites, especially those that persist in human blood. Potential intracellular targets and health risks are also discussed.

“…The methyl sulfone metabolites appear to be more persistent than the PCBs [6]. In addition, MeSO 2 -PCBs possess slightly lower lipophilicity than the corresponding parent PCB congeners, and are still sufficiently hydrophobic to accumulate in the food chain [5].…”

Abstract-Great concerns have been raised about the fate and effects of polychlorinated biphenyls (PCBs) and other organic contaminants contained in electronic waste (e-waste) exported from industrialized countries at midlatitudes to subtropical and tropical regions. Information on the metabolites of these chemicals, for example, methylsulfonyl-PCBs (MeSO 2 -PCBs) in wildlife from the later regions is scarce. In the present study, 17 MeSO 2 -PCBs, including five chiral congeners, were detected in the muscle, liver, and brain tissues of two benthic fish species-northern snakehead and mud carp-from a small pond near an electronic waste recycling site in South China. The mean concentrations of the sum of the MeSO 2 -PCBs ranged from 80 to 340 ng/g lipid weight in the tissues, with relative higher levels in the liver than the muscle and brain tissues. These levels were one order of magnitude greater than the highest levels of MeSO 2 -PCBs previously reported in fish. The 3 0 -MeSO 2 -CB 87, 3 0 -and 4 0 -MeSO 2 -CB 101, 4-MeSO 2 -CB 110, and 4-MeSO 2 -CB 149 were dominant, collectively comprising more than 55% of the total MeSO 2 -PCBs. Except for 4-MeSO 2 -
