“…Contamination levels in horse mackerel samples show values, in terms of total DDT concentration, similar to those found by Coelhan et al (2006) in horse mackerel and lower than those reported by Tanabe et al (1997a), but in whiting higher than those reported from the Marmara Sea in Turkey (Coelhan et al, 2006) and lower than those reported by Tanabe et al (1997a) from the Black Sea. This study about contamination in horse mackerel shows values, in terms of total indicator PCB concentration, lower than those found in horse mackerel from the Marmara Sea in Turkey (Coelhan et al, 2006) but in whiting higher than those reported by Coelhan et al (2006) and lower than those reported by Tanabe et al (1997b).…”

“…Our results are also in accordance with this finding. In particular, the ranges of total PCB (∑ICES7) p,p'-DDE/∑p,p'-DDTs (∑p,p'-DDTs=p,p'-DDT+ p,p'-DDE+p,p'-DDD) below 0.6 has been considered as fresh DDT exposure (Aguilar, 1984;Coelhan et al, 2006). In the present study, the ranges of this value in fish samples was 0.50-0.70 in whiting and 0.43-0.86 in horse mackerel respectively.…”

“…Indicator PCBs and total DDTs were determined in different fish species caught from Marmara Sea, Turkey. The results were 209.36 and 455.09 ng/g fat weight for horse mackerel, 363.85 and 577.43 ng/g fat weight for whiting respectively (Coelhan et al, 2006). In another study PCBs and DDTs were determined in different fish species in Black Sea.…”

The concentrations of indicator polychlorinated biphenyls (PCBs) and 1,1,1-trichloro-2,2-bis-chlorophenyl-ethane (DDT) and its metabolites were determined in whiting (Merlangius merlangus euxinus N. 1840) and horse mackerel (Trachurus mediterraneus S. 1868) from the İzmit Bay, Turkey. The results showed that the levels of the total PCBs ranged from 1.49 to 39.69 ng/g fresh weight in whiting, and from 5.61 to 58.61 ng/g fresh weight in horse mackerel. Total DDTs concentrations were found from 1.08 to 66.73 ng/g fresh weight in whiting, and 4.69 to 116.25 ng/g fresh weight in horse mackerel. Concentrations of PCBs and DDTs in horse mackerel were found higher than those in whiting. Congeners IUPAC Nos. 52, 101, 153 were found frequently in whiting and horse mackerel samples. Analysis of DDT and its metabolites showed that p,p'-DDE was dominant in both of the fish species. Total PCB and DDT concentrations in fish samples were found lower than the maximum residue limits fixed by legislations.Keywords: Fish, organochlorine contaminants, Marmara Sea.

Total PCB'lerin konsantrasyonları mezgit balıklarında 1,49-39,69 ng/g yaş ağırlık olarak bulunurken, istavrit balıklarında ise 5,61-58,61 ng/g yaş ağırlık olarak tespit edilmiştir. Total DDT konsantrasyonları ise mezgit balığında 1,08-66,73 ng/g yaş ağırlık olarak bulunurken, istavrit balıklarında 4,69-116,25 ng/g yaş ağırlık olarak bulunmuştur. PCB ve DDT konsantrasyonları istavrit balığında mezgit balığına kıyasla daha yüksek bulunurken, her iki balık türünde de tespit edilen en baskın bileşenler PCB52, PCB101, PCB153 ve p,p'-DDE'dir. Sonuç olarak total PCB ve DDT konsantrasyonları tebliğlerde belirtilen maksimum kalıntı limitlerinin altında bulunmuştur.Anahtar Kelimeler: Balık, organik klorlu bileşikler, Marmara Denizi.

“…Levels of indicator PCBs determined are lower than the levels found in the same fish species in the Marmara Sea by Coelhan et al (2006). Contamination levels in anchovy and horse mackerel show values, in terms of total PCDD/Fs (TEQ) concentration, similar to those found by Bayarri et al (2001) at the Adriatic Sea.…”

Samples of three mainly consumed three edible fish species, whiting, horse mackerel and anchovy, from the Black Sea were analyzed for PCDD/Fs, dioxin-like PCBs and indicator PCBs. The results showed that PCDD/F-TEQ, dl-PCBs-TEQ and indicator PCBs concentrations ranged between 0.28-0.91 pg/g fresh weight product, 0.56-1.89 pg/g fresh weight product and 3.05-10.94 ng/g fresh weight product, respectively. It is observed that with increasing fat content of the fishes most of congeners' concentrations increased. Measured values were below the maximum residue levels indicated in the EU Commission Regulation "Setting maximum levels for certain contaminants in foodstuffs".

Abstract.Concentrations of organochlorine compounds such as polychlorinated biphenyls (PCBs), DDT and its metabolites, hexachlorobenzene (HCB) and hexachlorobutadiene (HBDE) were determined in three fish species: goby (Neogobius melanostomus), golden grey mullet (Mugil auratus) and silverside (Atherina boyeri). Samples were collected from the Lake Varna and the Lake Beloslav in 2014. The edible fish tissues were analyzed in order to investigate the presence of pollutants in species from the lakes near Varna City, Bulgaria and compared the results to the levels in other aquatic ecosystems. The fifteen congeners of PCBs, HCB, HCBD, DDT and its two main metabolites DDE and DDD were determined by capillary gas chromatography system with mass spectrometry detection. The OCPs levels in the wild fish were found in the order DDTs > PCBs. The other contaminants HCB and HCBD were not detected or were below the analytical detection limit. Among the pesticides, essentially only the metabolites p, p'-DDE and p, p'-DDD were found.The concentrations of DDTs were determined from 2.66 to 17.97 ng/g wet weight and PCBs concentrations were found from 0.43 to 8.05 ng/g ww (in goby and golden grey mullet, respectively). The sum of the six Indicator PCBs did not exceed the European maximum limit 75 ng/g wet weight. The concentrations of DDTs and PCBs were found lower compared to those in similar fish species from other aquatic ecosystems.
