“…The best datasets exist for eels, which often have higher contamination than other freshwater species from the same site (eg. Downs et al, 1999;Edwards et al, 1999;Noel et al, 2013;Yamaguchi et al, 2003). Noel et al (2013) provided an overview for recent European monitoring data in several species of fish including roach and eel: For eel the overall range in concentrations was very large from about 10 to 800 µg/kg but most studies had average concentrations around 100-200 µg/kg, whereas in roach the concentrations were mostly between 50 and 100 µg/kg with the exception of some higher values in Slovakia and the Czech Republic.…”

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...

“…Eels in two Spanish rivers had comparable mean mercury concentrations between 0.155 and 0.533 mg/kg [42], and in Portuguese lagoons, eels contained between 0.55 and 0.285 mg Hg/kg [43]. Noël et al [25] reviewed further data from the studies in other countries including Poland, the Czech Republic, Germany, UK, Slovenia and Hungary and reported a range of values between 10 and 800 μg/kg. In their study of French rivers, they found mean concentrations of 0.199 mg/kg and reported a strong positive correlation between Hg concentration and the condition factor (p < 0.0001) but no correlation between Hg levels and body weight or length.…”

Contaminant levels in the European eel (Anguilla anguilla) in North Rhine-Westphalian rivers

2014

Background: Populations of the European eel (Anguilla anguilla) are declining rapidly and are now considered below safe biological limits. High pollution levels are one of the possible reasons for this decline. Contaminant levels are also of concern with regard to human consumption. This study examined the contamination levels of eels from the North Rhine-Westphalian catchment area of the Rhine and from adjacent rivers. A total of 119 eels from 13 sampling sites were analysed for polychlorinated dibenzo-p-dioxins and furans (PCDD/PCDFs), polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), mercury, perfluorooctane sulfonate (PFOS) and hexachlorobenzene (HCB). Results: North Rhine-Westphalian eels had very high levels of contaminants comparable to eels from other European water bodies which are strongly influenced by anthropogenic activities. Mean values for PCDD/PCDFs ranged between 0.5 and 5.4 pg WHO 2005 toxicity equivalents (TEQ)/g, for PCDD/PCDF + dl-PCBs between 6.3 and 44.7 pg WHO 2005 TEQ/g, for indicator PCBs between 165 and 1,630 ng/g wet weight (ww), for 6 PBDEs between 9.2 and 242 μg/kg ww, for mercury between 0.069 and 0.314 mg/kg ww, for PFOS between 8.3 and 49 μg/kg ww and for HCB between 3.4 and 50 μg/kg ww. For certain sampling sites, high contamination contents of the eels could be attributed to local sources. Congener patterns for PCBs and PBDEs were described, and biota to suspended matter ratios were calculated. Conclusions: Pollution levels in eels from North Rhine-Westphalia are declining with regard to some contaminants but are still very high. Due to the high contaminant contents, eels from the rivers investigated are not suitable for human consumption. Furthermore, the concentrations of endocrine disrupting contaminants such as PCBs, PCDD/PCDFs and PBDEs in the eels are in a range which might have deleterious effects on the eel populations.

“…However, in the case of higher concentrations of those metals, they also become toxic and considered as pollutants. The results of many researches show bioaccumulation of metal pollutants from the water in various tissues of aquatic organisms [12][13][14][15]. Various species of fi sh can be bioindicators of contamination with heavy metals and others pollutants [16].…”

The aim of this study was the investigation of water, sediments and fi sh tissues contamination with heavy metals. All samples were taken from the Danube River in Belgrade region, a location upstream from Batajnica. Concentrations of Cd, Hg and Pb in water samples were not detected, while concentrations of Zn, Fe, Cu and As were in the range of 0.004 -0.330 mg L -1. Iron was the most deposited metal in sediment samples in contrast to water samples where all investigated metals were detected. For the purpose of heavy metals determination in fresh fi sh tissue, fi fteen samples of three different fi sh species, silver carp (Hypophthalmichthys molitrix), common carp (Cyprinus carpio) and wels catfi sh (Silurus glanis) were collected. Concentrations of Pb, Cd, As and Hg were determined in the digestive tract, liver and muscle by absorption spectroscopy. The highest concentration of Pb was in the digestive tract in all three fi sh species, ranging from 0.036 to 1.518 μg g -1 , while Cd was mostly deposited in the liver. Concentrations of As were in the range of 0.36 -0.73 μg g -1 in Hypophthalmichthys molitrix, 0.013 -0.18 μg g -1 in Cyprinus carpio and 0.003 -0.005 μg g -1 in Silurus glanis tissues, while the content of Hg was equal in all tested tissues of carp. Concentrations of all metals were found to be present in the fi sh samples at different levels, but these values are under the maximum residual levels prescribed by the European Union (EU) and the maximum allowed concentrations (MAC) for Serbia, so the fi sh meat is acceptable for the human consumption.
