“…In China, a total diet study was also conducted in Hong Kong in 2010 (FEHD, 2011), the mean exposure of adult population, 0.73 pg TEQ kg À1 bw day À1 (WHO-TEF of 1998), was concordant with average exposure of Chinese adult population in present study. Moreover, other methods, including market basket study, and monitoring program, were also applied to evaluate the dietary intake for residents in many countries (Arisawa et al, 2008;Perelló et al, 2010;Marin et al, 2011;Törnkvist et al, 2011;Rauscher-Gabernig et al, 2013;Husain et al, 2014). Some studies have indicated that cooking process might be a source of PCDD/Fs and dl-PCBs Wu et al, 2011).…”

“…In C. aceratus, we found that the BEQs were comparable to the TEQs calculated on the basis on the WHO PCB -TEFs for salmonid fish species (Van den Berg et al, 1998). In comparison to fish from the northern hemisphere (Husain et al, 2014), Antarctic fish had about twenty times lower BEQ values in their muscle. In contrast, the BEQs in the ovaries of C. gunnari were much higher than the WHO PCB -TEQs calculated for their ovaries.…”

Persistent organic pollutants in tissues of the white-blooded Antarctic fish Champsocephalus gunnari and Chaenocephalus aceratus

The global occurrence of persistent organic pollutants (POPs) continuously contributes to their accumulation also in remote areas such as the Antarctic Ocean. Antarctic fish, which hold high trophic positions but appear to possess low endogenous elimination rates for chemicals, are expected to bioaccumulate POPs with rising anthropogenic pollution. Using a chemical-analytical method, we measured concentrations of PCBs, PBDEs, HCBs, HCH and DDTs and determined toxic equivalents (TEQs) and bioanalytical equivalents (BEQs) in muscle and ovaries of Antarctic icefish caught in the Southern Ocean around Elephant Island. We used two species with different feeding habits and trophic web positions: the planktivorous Champsocephalus gunnari and the piscivorous Chaenocephalus aceratus. Our results revealed higher contaminant levels in ovary than in muscle tissues of both species. Most analytes concentrations and the TEQs (0.2-0.5) and BEQs (0.2) were lower as in temperate species. Comparison with literature data points to higher PCB (20-22 ng g(-1) lipid weight (lw)) and DDT (7-19.5 ng g(-1) lw) concentrations than those measured in icefish in the 90's. For the other contaminants, we could not identify temporal trends. We found a higher bioaccumulation of contaminants, particularly HCB and DDTs, in C. aceratus (6.2 & 19.5 ng g(-1) lw, respectively) than in C. gunnari (3.8 & 7.0 ng g(-1) lw, respectively). However, there was no general species-specific accumulation pattern of the different toxicant classes between the two icefish. Thus, the expected link between contaminant burdens of C. aceratus and C. gunnari and their ecological traits was only weakly supported for these species.

“…Sample preparation and analysis of dioxins and dioxinlike compounds were performed according to the standard procedure of the manufacturer (Bio Detection Systems BV, Amsterdam, The Netherlands; Stronkhorst et al 2002;Husain et al 2014). Briefly, an aliquot of homogenized fish muscle samples (≤0.5 g lipid) was mixed with 30 ml ultra-pure water and isopropanol (1:1 v. v.) followed by an extraction with 30 ml of hexane with 3 % diethyl ether.…”

The dioxin and dioxin-like compounds are regarded as one of the most toxic group of environmental contaminants. Food for the commercial market is regularly monitored for their dioxin levels and the concentration allowed in food is strictly regulated. Less is known about locally caught fish from recreational fishing, which is often brought home for consumption. This can be fish caught from nearby lakes or streams or fish with marine origin close to industrial areas or harbours that are not regularly monitored for their dioxin levels. In this study, we established collaboration with schools in 13 countries. We received 203 samples of 29 different fish species of which Atlantic cod was the most abundant followed by brown trout and pollock. In general, the majority of samples from the participating countries had low concentrations (between 0.1 and 0.2 pg/g chemical-activated luciferase gene expression toxic equivalency wet weight (CALUX TEQ w.w.)) of dioxins and dioxin-like PCBs. Only 18 samples had concentrations above 1 pg/g CALUX TEQ w.w., and only 2 dab samples had concentration above maximum levels set by the European Commission. The Atlantic cod samples showed a significant reduction in the concentrations of dioxins with increasing latitude indicating less contamination of dioxin and dioxin-like compounds in the north of Norway. The results indicate that a moderate consumption of self-caught fish at presumed non-contaminated sites does not represent a major risk for exposure to dioxins or dioxin-like compounds at concentrations associated with adverse health effects. Recreational fishermen should, however, obtain knowledge about local fish consumption advice.
