“…The total PAH aqueous concentrations ranged from 17 to 381 ng g − 1 in 2009 (Table S1) which were comparable to those in 2008 of 15 to 354 ng L − 1 in the same area (Wang et al, 2013b). The total PCB aqueous concentrations ranged from non-detectable to 44 pg L − 1 (Table S1) which were also comparable with the results in the same area in 2008 of 14.9 to 92.6 pg L − 1 (Wang et al, 2013b) and in 2004 of non-detectable to 5.9 pg L − 1 (Chen et al, 2008).…”

“…Chlorinated contaminants such as polychlorinated biphenyls (PCBs) and chlorinated benzenes (CBs) have been detected in the Yangtze River water and sediments in low concentrations (Jiang et al 2000;Wang et al 2009). PCBs are anthropogenic environmental pollutants, which originate from the recycling procedures or dumping of electronic wastes (Shen et al 2009;Liu et al 2008).…”

Several groups of bacteria such as Dehalococcoides spp., Dehalobacter spp., Desulfomonile spp., Desulfuromonas spp., or Desulfitobacterium spp. are able to dehalogenate chlorinated pollutants such as chloroethenes, chlorobenzenes, or polychlorinated biphenyls under anaerobic conditions. In order to assess the dechlorination potential in Yangtze sediment samples, the presence and activity of the reductively dechlorinating bacteria were studied in anaerobic batch tests. Eighteen sediment samples were taken in the Three Gorges Reservoir catchment area of the Yangtze River, including the tributaries Jialing River, Daning River, and Xiangxi River. Polymerase chain reaction analysis indicated the presence of dechlorinating bacteria in most samples, with varying dechlorinating microbial community compositions at different sampling locations. Subsequently, anaerobic reductive dechlorination of tetrachloroethene (PCE) was tested after the addition of electron donors. Most cultures dechlorinated PCE completely to ethene via cis-dichloroethene (cis-DCE) or trans-dichloroethene. Dehalogenating activity corresponded to increasing numbers of Dehalobacter spp., Desulfomonile spp., Desulfitobacterium spp., or Dehalococcoides spp. If no bacteria of the genus Dehalococcoides spp. were present in the sediment, reductive dechlorination stopped at cis-DCE. Our results demonstrate the presence of viable dechlorinating bacteria in Yangtze samples, indicating their relevance for pollutant turnover.

“…First results of POP concentrations (Wang et al 2009a) back-calculated to water concentrations showed obvious regional variations of PAH, PCB, and OCP levels in the Fig. 2 Potential holistic experimental and theoretical approaches to characterize environmental exposomes by means of chemical analysis, biomarkers of exposure, bioassay, and risk/effect modeling of tentative mixtures including translational comparisons between species and chemicals reservoir and are compared to other matrices as well as effectoriented investigations such as Ah receptor and ER receptor agonists or antagonists.…”

“…The comparison of chemical-oriented and effect-oriented analyses revealed large differences between known and unknown compounds, which caused EROD activity and ER antagonits of sample extracts. Unknown compounds in TGR are suspected to be responsible for the high anti-estrogenic and EROD activity in extracts of suspended particles (Wang et al 2009b). To complement the exposome of TGA at the current conditions, a second matrix sediment has been selected (Bi et al, this issue).…”

Exposomic studies of the rapidly changing environment of the Three Gorges Reservoir (TGR) after its impounding is elaborated as a novel field of human and environmental research. Molecular exposomics is focused on the measure of all exposures to molecules and especially persistent organic pollutants-like compounds are of emerging interest due to their lifetime existence in the environment and humans. Theoretical considerations in general and particular for the TGR are deduced and presented using quantitative approaches for this research field. Since exposomics is strongly time-dependent, a theory is presented to link extension of exposure, time, and related effects. Similarity to the first law of thermodynamics is outlined. On top of this, the integrated use of biomarkers is presented employing chemical analysis for biomarkers of exposure and effects, biomarkers in vivo, in vitro approaches and the link between chemical mixtures, and the onset of disease and lethality. Besides real organisms, also virtual organisms are favored to act as well-defined subcompartments such as fat of biota and with respect to time of exposure. Exposomics is the perspective of risk evaluation and chronic exposures in the running century. It needs novel theories, approaches, and integrated action between medical and environmental disciplines. The existing knowledge about molecular stressors has to be assembled and put into a context especially with respect not only to time resp. lifetime exposure of humans but also eco-toxicological findings by using highly conserved phylogenetic mechanisms to enable links between human and risks of environmental biota. The TGR is a good example not only to employ biomonitoring of real but also virtual organisms due to the lack of established ecotopes in this changing environment so far. Progress in understanding long-term risks requires a proper theory as well as novel tools such as virtual organisms. On top, multidisciplinary approaches and the utilization of existing knowledge about the exposure of the environment and humans have to be merged and directed into mutual concepts. Effect-oriented and chemical analysis must be designed time-oriented to determine lifetime exposures of mankind and nature. Perspectively, a first attempt about exposomic theory and concepts is proposed and has to be developed experimentally further enclosing virtual besides of real organisms and compartments. Environmental and human exposomics have to be considered as a Res (2013) 20:7057-7062 DOI 10.1007/s11356-012-1319 unified global issue in order to effectively utilize their mutual existing knowledge most effectively. The TGR is a challenging model system aiming this objective.
