“…The concentrations of ∑PAHs in muscle tissues of the investigated fish (12.5-22.0 ng g −1 ww) were comparable to the concentrations in fish muscle collected from other locations in China, such as: freshwater fish collected from markets in Hong .4 ng g −1 ww, Cheung et al, 2007), fishponds in Pearl River .1 ng g −1 ww, Kong et al, 2005), Poyang Lake (53.9-513 ng g −1 ww, Zhao et al, 2014) and Mai Po Marshes Nature Reserve in Hong ng g −1 dw, Liang et al, 2007). The concentrations were also comparable to those in fish muscle from coast of Europe, Asia, Africa and Latin America (Musa Bandowe et al, 2014;Soclo et al, 2008;Rojo-Nieto et al, 2014;Mashroofeh et al, 2015).…”

“…The high level of lipid in muscle tissue of grass carp may be the reason of such variety. Cheung et al (2007) also reported that grass carp showed a lowest level of ∑ PAHs among their investigated freshwater fish from Hong Kong markets. The feeding habit of grass carp on grass and other submerged higher plants may partly explain its relatively lower enrichment of PAHs in its muscle.…”

“…Relative higher concentrations of PAH congeners with lower octanol-water partition coefficients (Log Kow less than 5.0) in fish are due to their higher gill-water transfer efficiencies as suggested by Cheung et al (2007), while lower residues of compounds with higher molecular weight (HMW) and higher Kow (Log Kow larger than 5.0) might be mainly attributed to the enhanced biotransformation as well as decreased gut assimilation in fish (Liang et al, 2007). Thus the finding of PAH congeners pattern in fish of the present study may suggest that the investigated fish in TGR can metabolize HMW PAHs more readily than the LMW PAHs (e.g., naphthalene, phenanthrene).…”

“…Compared with published data, the total DDT concentrations in mitten-handed crabs from this study were comparable to those (mean, 12.8 ng g −1 ww) in sea crabs (Scylla serrata and Ovalipes punctatus) collected from South China [25], but were less than those in river crabs (526−821 ng g −1 lw) collected from Qiangtang River of China [26], and also less than those in most of sand crabs (43-13000 ng g −1 lw) along the California coast [20,27,28]. Moreover, the total DDT contents in loaches determined in this study were found to be less than those (125−127 ng g −1 ww) in rice field eel (Monopterus albus) obtained from Hong Kong markets [29].…”

In order to assess the influence of long-term irrigation of polluted river water on the ecological health of the rice fields in the low reach of Liaohe River Plain, a series of environmental samples and biological samples in rice fields, including sediments, paddy soils, mitten-handed crabs (Eriocheir sinensis), loaches (Misgurnus anguillicaudatu) and frog (Hoplobatrachus tigerinus), were collected from the area far away from industrial zones, and polychlorinated biphenyls (PCBs) and organochlorine pesticides (HCH, DDT, HCB and Mirex) were analyzed by high resolution gas chromatography coupled with high resolution mass spectrometry (HRGC/HRMS). The comparison of pollutant concentrations and profiles verified that the significant contribution of river water irrigation to PCBs contaminations in paddy soils and the mutual influence of organochlorine pesticide contamination between river sediments and paddy soils. Bioaccumulations of PCBs and organochlorine pesticides in mitten-handed crabs and loaches were site-specific, suggested that they were both the good indicators of ecosystem health. Mitten-handed crabs had the highest capacity to accumulate PCBs and organochlorine pesticides, and also they had the strong ability to degrade these pollutants in their bodies, especially for DDT and HCH. The biota-soil accumulation factors (BSAF) of HCH, DDT, Mirex, HCB Σ Σ and PCB Σ s in mitten-handed crab were calculated to be 24.5, 15.3, 122.2, 28.1 and 54.6, respectively. In view of the strong bioaccumulation ability, the health risk should be concerned for the cultivation of mitten-handed crabs in paddy fields in the low reach of Liaohe River Plain.

“…For chicken wing, skin or meat were dissected and were analyzed separately. All samples were freeze-dried and extracted as described previously (Cheung et al, 2007). Briefly the freeze-dried sample (3 g) was mixed with 50 ml of dichloromethane:acetone (1:1), and was Soxhlet extracted in a shaking incubator (JULABO Labortechnik, GMBH, Seelbach, West Germany) at 40 1C for 18 h. The organic phase was collected and was then concentrated using a rotary evaporator (BÜ CHI) at 60 1C until 2 ml of solution was left.…”

Endocrine disrupting chemicals (EDCs) consist of a diverse group of industrial chemicals and pharmacological agents. The use of instrumental analyses as the first screening tool might not be cost-effective to identify the existence of enormous numbers of chemical contaminants in environments. Also, knowledge of the concentration of individual residues is difficult to use to evaluate biological impacts of contaminants to wildlife and humans. The primary objective of the present study was to develop and to test the feasibility of using a battery of exposure biomarkers for the rapid-screening of various endocrine disrupting activities present in food. The measurement of the EDC-elicited activities involved various (i) receptor-mediated responses, including androgenic, estrogenic, dioxin-like, glucocorticoid-like, progesterone-like, peroxisome proliferator-like and retinoid-like as well as (ii) the non-receptor mediated responses through modulation of cellular reactive oxygen species (ROS) and ATP content. Samples of both local and imported pork, beef and chicken as well as freshwater and seawater fishes were collected. Extracts of different foods exhibited various dioxin-like and ''hormonal'' activities. Fish and chicken skin were found to be the major source of exogenous ''hormonal'' and dioxin-like substances in diets. Extracts of beef and pork contained lesser potencies of hormonally-active agents. Our data suggest that the proposed EDC-screening platform may be useful in a risk assessment for the routine monitoring of EDCs in foods. Continuous monitoring and research is warranted to assess the physiological consequences of the consumption.
