“…The PCDD/F profile in herring from the present study was similar to the profile of herring and herring products from northwest Europe (including the Baltic Sea [25]). A food web study of Baltic herring showed that the contamination profile for PCBs was similar to the profile in the diet of herring (mysis and zooplankton) [38]. It is likely that the North Sea herring contamination profile is also dictated by the diet, but contamination data of the diet were not available at the time of writing.…”

Fish from Dutch markets were analysed for concentrations of polychlorinated dibenzo-p-dioxins/dibenzofurans (PCDD/Fs) and dioxin-like polychlorinated biphenyls (DLPCBs) and compared with the new European maximum residue levels (MRLs), set in 2006. In a first study on 11 different fish and shellfish from various locations, concentrations of PCDD/Fs were nearly all below the MRL for PCDD/Fs [4 pg toxic equivalents (TEQ) per gram wet weight (ww)] and nearly all below 8 pg total TEQ/g ww, the new MRL for the sum of PCDD/Fs and DL-PCBs. Some samples exceeded the total TEQ MRL, such as anchovy, tuna and sea bass. Furthermore, 20 (out of 39) wild eel samples exceeded the specific MRL for eel (12 pg total TEQ/g ww), as the study revealed PCDD/F TEQ levels of 0.2-7.9 pg TEQ/g ww and total TEQ values of 0.9 to 52 pg/g ww. TEQ levels in farmed and imported eel were lower and complied with the MRLs. Smoking eel, a popular tradition in the Netherlands, only had marginal effects on PCDD/F and DL-PCB concentrations. Owing to volatilization, concentrations of lowerchlorinated PCBs were reduced to below the limit of quantification after smoking. DL-PCBs contributed 61-97% to the total TEQ in all eel samples. This also holds for other fish and shellfish (except shrimps): DL-PCB contributed (on average) from 53 (herring) to 83% (tuna) to the total TEQ. Principal-component analysis revealed distinctive congener profiles for PCDD/Fs and non-ortho PCBs for mussels, pikeperch, herring and various Mediterranean fish. The application of new TCDD toxic equivalency factors (TEFs) set by the World Health Organization in 2006 (to replace the 1997 TEFs) resulted in lower TEQ values, mainly owing to a decreased mono-ortho PCB contribution. This decrease is most pronounced for eel, owing to the relative high monoortho PCB concentrations in eel. Consequently, a larger number of samples would comply with the MRLs when the new TEFs are applied. The DR CALUX® assay may be used for screening total TEQ levels in eel, in combination with gas chromatography-high resolution mass spectrometry confirmation of suspected samples. An almost 1:1 correlation was found when the 1997 TEFs were applied, but, surprisingly, a 1.4-fold overestimation occurred with application of the 2006 TEFs.

“…OC pesticides are considered persistent pesticides. These pesticides have long environmental half-lives and tend to bioaccumulate in humans and other animals and thus biomagnify up to 70 000 times in the food chain (Niethammer et al 1984;Albanis et al 1996;Nendza et al 1997;Strandberg et al 1998;Borga et al 2001). Because migratory birds and other animals are at the top of the food chain, they carry these persistent compounds with them wherever they go and are then transferred to the very top of the food chain, humans (Bro-Rasmussen 1996).…”

“…This reflects the global scale of chemical pollution of the environment. Researches proved that organochlorine compounds have the ability to accumulate in organisms of the subsequent trophic levels (Strandberg et al 1998, Ebadi et al 2005, El-Mekkawi et al 2009). Organochlorine fungicides posed health hazards and put human life at risk many times in the past.…”

The aim of this project was to study the fate of chemically persistent organochlorine xenobiotics in the marine link of the food web, between penguins and herrings (Clupea harengus), which are the only food for Spheniscus demersus from the Gdańsk Zoo. Concentrations of hexachlorobenzene (HCBz), pentachlorobenzene (PCBz), trichlorobenzene (TCBz) and the γ-HCH isomer were determined in Baltic herrings, in muscles, fat and liver of penguins, unhatched eggs, contour feathers and guano. The highest concentrations of fungicides were observed for HCBz. Fungicides were not detected in the liver of penguins and herrings. The bioaccumulation factor (BAF) for fungicides reached the highest values in the penguin brain. The highest biomagnification factor (BMF) for PCBz was determined in the muscle tissue and for lindane -in liver. It was confirmed that detoxification of penguins occurred through deposition of fungicides and lindane in guano and through epithelial tissue and eggs.
