“…Similarly, DP concentrations in liver of common carp were higher than those in muscle despite of the higher lipid contents of muscle (Zeng et al, 2014). The results were consistent with the present study and further suggested the sequestration of DP by hepatic proteins although this was not identified.…”

“…Zhang et al (2011a,b) reported high affinity of anti-DP to brain in fish. The liver of rat and common carp also show preference for anti-DP in two exposure experiments (Li et al, 2013a;Zeng et al, 2014). To date, no studies have reported a higher affinity to anti-DP for fat tissue in organisms to our best of knowledge.…”

“…Among the three tissues with relative high f anti values , fat and brain are poor blood perfusion organs. Serum exhibited lower f anti value than other tissues when common carp exposed to DP technical mixtures (Zeng et al, 2014). This could be a possible reason for the relative lower f anti for well blood perfusion organ such as kidney, lung, and heart (0.55-0.56), and relative higher f anti for poor blood perfusion organs observed in the present study.…”

“…Tissue-specific accumulation of DP could be one reason for this discrepancy (Peng et al 2012;Zeng et al 2014). In addition, fish sizes for both mud carp and northern snakehead in the study of Wu et al (2010b) (5-18.1 cm) were much smaller than those in the present study (23-32 cm).…”

Halogenated organic pollutants (HOPs)-including organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), polybrominated diphenylethers (PBDEs), polybromobiphenyls (PBBs), dechlorane plus (DP), tetrabromobisphenol A (TBBPA), and hexabromocyclododecanes (HBCDs) as well as PCB metabolites (methylsulfone [MeSO 2 -]) and hydroxylated (OH-) PCBs and OH-PBDEs-were determined in the serum of mud carp and northern snakehead from an electronic-waste (e-waste) site in South China. The average concentrations (mean ± SD) of RPCBs, RPBDEs, ROCPs, RPBBs, RTBBPA, RHBCDs, and RDP were 1410 ± 324, 70 ± 20, 3.0 ± 0.4, 2.8 ± 0.8, 1.6 ± 0.4, 1.0 ± 0.2, and 0.3 ± 0.03 ng/g wet weight (ww) in mud carp and 6430 ± 781, 468 ± 49, 22.4 ± 1.1, 7.0 ± 0.6, 2.9 ± 2.3, 5.5 ± 1.1, and 4.6 ± 0.6 ng/g ww in northern snakehead, respectively. MeSO 2 -PCBs, OH-PCBs, and OH-PBDEs were detected at a total concentration of 0.44 ± 0.03 and 9.7 ± 0.3 ng/g ww in mud carp and northern snakehead, respectively. The congener profiles of PCBs, PBDEs, OH/ MeSO 2 -PCBs, and OH-PBDEs were found to be significantly different between the two fish species, possibly as a result of species-specific bioaccumulation and/or metabolism of the HOPs. Chirality of ten PCB congeners and a-HBCD, as well as the f anti values of DP in the serum samples, supported the species-specific biotransformation of HOPs. Furthermore, the presence of covaried and counter-varied enantiomeric fractions of PCBs between the two fish species indicated species-and congener-specific enantiomer enrichment of PCBs.Halogenated organic pollutants (HOPs), such as polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs) (e.g., DDT and its metabolites DDD and DDE), and halogenated flame retardants (e.g., polybromobiphenyls [PBBs], polybrominated diphenylethers [PBDEs

“…If PCBs are absorbed at a lower rate than the food, then the PCB concentration in the feces will increase, and vice versa (Zeng et al, 2014b). The chemical losses from feces to water are insignificant (unpublished data) during 10-h feces accumulation because of the high lipophilic character of the PCBs (K OW > 10 4 ).…”
