a Eight aquatic biota species were collected from an e-waste dismantling area in East China to investigate bioconcentration and trophic transfer of polychlorinated biphenyls (PCBs), polychlorinated dibenzo-pdioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs). The mean concentrations of PCBs varied widely from 6.01 Â 10 4 to 2.27 Â 10 6 pg per g dry weight (dw). The P 25 PCB concentrations in eels were significantly higher than those in other species. The levels of PCDD/Fs changed from 8.13 pg per g dw in toads to 617 pg per g dw in stone snails. World Health Organization-toxic equivalents (WHO 2005 -TEQs) ranged from 2.57 to 2352 pg WHO-TEQ per g dw with a geometric mean value of 64.7 pg WHO-TEQ per g dw, which greatly exceeded the maximum levels of 4 pg per g ww set by the European Commission. The log-transferred bioconcentration factors (BCFs) of 25 PCB congeners ranged from 1.0 to 6.6, with the highest value for CB-205 in crucian carp and the lowest value for CB-11 in frog. A parabolic correlation was observed between log BCF and log K ow (R 2 ¼ 0.53, p < 0.001), where the maximum value occurred at a log K ow of approximately 7. A similar correlation was also found in the plot of log BCF against the number of chlorine atoms of PCBs (R 2 ¼ 0.57, p < 0.001), indicating that mediumhalogenated congeners of PCBs are more easily accumulated by aquatic biota species. There were no significant correlations between the log-transferred concentrations and trophic levels of aquatic species, suggesting that trophic magnification for PCBs and PCDD/Fs was not observed in this study. Environmental impactE-waste dismantling regions have been the subject of great concern in recent years due to the serious environmental contamination associated with e-waste dismantling activities. As a notorious e-waste recycling area in East China, Taizhou has been a hot spot for persistent organic pollutant (POP) research. The present study was conducted to investigate the bioconcentration and trophic transfer tendencies of PCBs and PCDD/Fs in various aquatic biota species in this ewaste area. The high concentrations of POPs in these species reected the lasting impact of e-waste recycling activities on the local environment over more than three decades. Bioconcentration of PCBs was ubiquitously observed in all the species, and signicant parabolic relationships were found between log BCFs and the number of chlorine atoms of PCB congeners as well as their log K ow s. The present results provided important information about the bioaccumulation tendency of POPs in aquatic biota species.

“…Residues of POPs, such as dichlorodiphenyltrichloroethane (DDT), hexachlorobenzene (HCB), hexachlorocyclohexane (HCH), chlordane, polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs), and polychlorinated biphenyls (PCBs) have been found in marine fish, mollusks, crabs, and shrimp in the coastal areas of China (Yang et al 2006;Jiang et al 2007;Liu et al 2007;Miyake et al 2008). Residents of coastal areas who have a habit of consuming sea fish are more exposed to POPs (Leng et al 2009).…”

“…The dietary surveys conducted in 100 families indicated that the amount of fishes consumed ranged from 20 to 200 g/day, with a mean value of 40 g/day. The mean consumption of fish in this study compares with the dietary surveys conducted in China where the consumption of fish increased from 27.5 g/day in 1989 to 30.5 g/day in 1997 [28]. In a survey conducted in 325 families in Coimbatore city, India, Muralidharan et al [29] also reported a fish consumption of 47 g/day.…”

ABSTRACT. Catfish (Chrysichthys nigrodigitatus) and mullet (Liza grandisquamis) were sampled from Lagos Lagoon and Agboyi Creek and analysed for alpha-BHC, beta-BHC, lindane, delta-BHC, heptachlor, heptachlorepoxide (B), aldrin, dieldrin, endrin, endrin aldehyde, endrin ketone, cis-chlordane, trans-chlordane, endosulfan 1, endosulfan 11, endosulfan sulphate, methoxychlor, p,p´-DDE, p,p´-DDD and p,p´-DDT. Sampling was conducted four times at the designated sites during the dry season months of December 2008 and February 2009 and the wet season months of May and September 2009. The muscle tissues and organs of the finfishes were subjected to cold extraction with petroleum ether/acetone (1:1 v/v) mixture and clean-up on silica gel adsorbents. A gas chromatograph coupled with electron capture detector (GC-ECD) was used to detect and determine the organochlorines. The residue levels of the fishes were higher in the Lagos Lagoon than in Agboyi Creek while a higher concentration of the residues was observed during the dry season. The female fishes accumulated higher organochlorines than the male fishes. The order of residue accumulation in the organs of the fishes was gills > livers > large intestines > small intestines > kidneys > muscles. The dietary surveys indicated that the amount of fishes consumed ranged from 20 to 200 g/day, with a mean value of 40 g/day. The estimated daily intakes of the organochlorines were within the acceptable daily intakes while the levels of residues in the fishes were within the permissible residue limits.
