“…Another approach is in active biomonitoring for example with caged fish (Besse et al, 2012;Verweij et al, 2004), allowing them to accumulate chemicals both from the water (bioconcentration) and the food web (biomagnification). Fish can also be monitored for relatively polar contaminants, such as endocrine disrupting compounds, for example through examining the contents of their gall bladders (Fenlon et al, 2010).…”

J. 2013. The presence of EU priority substances mercury, hexachlorobenzene, hexachlorobutadiene and PBDEs in wild fish from four English rivers.Contact CEH NORA team at noraceh@ceh.ac.ukThe NERC and CEH trademarks and logos ('the Trademarks') are registered trademarks of NERC in the UK and other countries, and may not be used without the prior written consent of the Trademark owner.-1 - AbstractSince 2007 about 200 to 300 fish per year (generally roach (rutilus rutilus) but also a few bleak (alburnus alburnus) and eels (anguilla anguilla)) have been collected from a number of English river sites and stored at -80°C to build up a Fish Tissue Archive as a resource for the monitoring of pollutants. Some of the fish from the Fish Tissue Archive from the years 2007-2011 were analyzed for substances in current and proposed European legislation regarding environmental quality standards (EQS) in biota. It was found that mercury exceeded the EU EQS of 20 µg/kg in 79 % of samples with an average and median of 31 and 29 µg/kg. The legacy fungicide hexachlorobenzene (HCB) was below the EQS of 10 µg/kg in all fish analyzed, with a maximum of 6 µg/kg in some eels. The legacy solvent hexachlorobutadiene (HCBD) was below the EQS of 55 µg/kg, being < 0.2 µg/kg in all samples where it was measured. The sums of six polybrominated diphenyl ethers (PBDEs) were several orders of magnitude higher than the new proposed 0.0085 µg/kg biota EQS. This study showed that the regular collection and analysis of whole body homogenate samples of relatively small native pelagic fish is suitable for the monitoring of contaminants capable of bioaccumulation. With regard to current or proposed EQS for EU countries, mercury and potentially PBDE in fish are of some concern in these English rivers.-2 - KeywordsEnvironmental quality standards UK fish mercury PBDE hexachlorobenzene priority substances rivers 1 Background and introduction LegislationThe Priority Substances Directive of the EU (Directive 2008/105/EC), which entered into force in January 2009, has the objective of protecting wildlife and humans from harmful effects of chemicals identified as priority substances in surface waters and to monitor trends of these chemicals. It aims to set environmental quality standards (EQS) for a number of chemical pollutants below which no harmful effects are expected to wildlife, or humans. There is an option for member states to set biota, or sediment, standards which offer "at least the same level of protection" as the water standards. For mercury, hexachlorobenzene (HCB) and hexachlorobutadiene (HCBD), the legislation states that water standards alone do not offer sufficient protection and therefore limits have been set for both water and biota and the legislation specifies that member states which choose not to apply the biota standard should set more stringent levels than those set out in the directive for the water standard. The EQS is set for prey tissue (wet weight) with member states being able to choose "the most appropriate indicator from among...

“…The DGT-labile metallic fraction, which is composed of free inorganic metals and weak organic complexes, has been shown to be close to the bioavailable fraction for freshwater organisms exposed only by aqueous route (Ferreira et al, 2009;Pellet et al, 2009). In terms of biological tools, bioaccumulation studies using encaged organisms have gained importance for environmental risk assessment (Bervoets et al, 2005;Besse et al, 2012). Indeed, metal determination in organisms provides an integrative measurement of local metal bioavailability at the transplantation site insofar as the different exposure routes of transplanted organisms and their ability to regulate internalized metals and geochemical effects on metal uptake are taken into account in the bioaccumulation process (Rainbow, 2007;Verschoor et al, 2012;Lebrun et al, 2014).…”

-Dredging generates remobilisation of sediments contaminated by non-degradable compounds such as metals, to which aquatic organisms can be exposed. This study aims at assessing the environmental impact of sediments remobilised in the Rhine River (France) during the dredging of Marckolsheim dam by pumping/dilution in 2013 on metal speciation and organisms' exposure. The monitoring coupling chemical and biological tools was performed 2 years before dredging operation on 2 sampling sites, upstream and downstream from the discharge of pumping/dilution, to acquire data on the natural variability of labile (DGTas passive samplers), dissolved and particulate concentrations of Cd, Co, Cr, Cu, Ni, Mn, Pb and Zn in Rhine during full hydrological cycles. In parallel, size-calibrated zebra mussels were transplanted at both sites to monitor continuously metal bioavailability from particulate and dissolved fractions. This long-term monitoring allowed the establishment of reference baselines of Rhine water and mussels' contamination levels and subsequently, the detection of averred environmental changes due to the dredging. Indeed, Co and Mn accumulations in mussels exposed to the discharge were consistent with increasing labile species in Rhine whereas ones of Cr and Pb were likely due to an enhanced particulate bioavailability. Whatever the exposure route, the mussels recovered their basal metal contents 2 weeks after the end of dredging, suggesting a transient impact of sediment remobilisation on bioaccumulation. This long-term monitoring highlights the interest of coupling chemical and biological time-integrated tools for a better assessment of environmental risks because metallic exchanges between organisms and their media are complex and metal-specific.Keywords: active biomonitoring / Dreissena polymorpha / DGT / metal bioavailability / natural variability Résumé -Évaluation de la remobilisation de sédiments contaminés par des métaux dans le Rhin au cours du dragage d'un barrage grâce à un suivi chimique et biologique à long terme.

“…The use of biota to monitor levels and trends of chemical contamination in water (i.e., chemical biomonitoring) has been used in several monitoring programs in coastal and continental waters (Besse et al 2012). Biota reflects the bio-accumulative and bioavailable fraction of contaminants in receiving waters, which are of direct eco-toxicological relevance.…”

The aim of this study was to investigate the relevance and the robustness of active and passive approaches used in freshwater biomonitoring with the ecologically relevant gammarid amphipod Echinogammarus veneris. To assess the contaminant bioavailability in two rivers of Latium (Central Italy), we measured the genotoxic potential in haemocytes by comet assay and metal bioaccumulation in tissues by analytical methods. We adopted an active strategy of exposure in situ and a passive method of sampling in situ. In the first case, the gammarids were exposed in cages in several sampling sites selected along two rivers, while in the sampling in situ, individuals were collected directly in the same sampling sites and then analyzed. The results indicate that the comet assay carried out on haemocytes from caged individuals proved to be a sensitive tool for freshwater genotoxicity monitoring. However, the sampling in situ is more appropriate for a realistic understanding of the presence of trace metal in E. veneris.
