    ABSTRACT: PCBs including “indicator” and “dioxin-like” congeners were measured in a marine gastropod, Hexaplex trunculus, from Mediterranean areas exposed to anthropogenic pressure, to evaluate their compliance with European Union (EU) legislation. Total PCB concentrations showed location-dependent variation, and were higher in samples from Ionian Sea-Taranto (1001 ng g−1 lipid weight) compared with those from Adriatic Sea-Bari (519 ng g−1 lipid weight) and Adriatic-Sea-Brindisi (253 ng g−1 lipid weight). All sample concentrations were compliant with EU regulation limits for the sum of six “indicator” PCBs (Ionian Sea-Taranto: 40.7 ng g−1 wet weight; Adriatic Sea-Bari: 24.0 ng g−1 wet weight; Adriatic Sea-Brindisi: 11.0 ng g−1 wet weight). Also “dioxin-like” PCBs content expressed as toxic equivalent (TEQ) values, in samples from Adriatic Sea (Adriatic Sea-Bari: 2.48 pg WHO-TEQ/g wet weight; Adriatic Sea-Brindisi: 2.14 pg WHO-TEQ/g wet weight), were below the limit, while the specimens from the Ionian Sea (Ionian Sea-Taranto: 3.53 pg WHO-TEQ/g wet weight) showed levels exceeding the maximum threshold.

    ABSTRACT: Concentrations of 11 polycyclic aromatic hydrocarbons (PAHs) and toxic metals (Hg, Cd and Pb) were measured in three fish species [(Raja miraletus (brown ray), Lepidorhombus whiffiagonis (megrim) and Lophius piscatorius (angler)] from Mediterranean Sea (Adriatic Sea). No significant difference in PAHs and metal concentrations was encountered among the fish species examined. Total PAH concentrations ranged from 209.9 ng g�1 wet weight to 227.2 ng g�1 wet weight. Low-molecular weight (two and three rings) PAHs were observed dominating over the high molecular weight (from four to six rings) PAHs. With regard to metals, Hg exhibited the highest concentrations (0.68–0.98 mg g�1 weight wet), followed by Pb (0.08–0.12 mg g�1 weight wet) and Cd (0.05–0.10 mg g�1 weight wet). The health risks by consumption of these species were assessed and did not present threat to public health concerning PAH, Pb and Cd intakes. However, the estimated exposure from Hg illustrates the importance of limiting the dietary consumption of larger-sized fish.

    ABSTRACT: Concentrations of 7 polychlorinated dibenzo-p-dioxins (PCDDs), 10 polychlorinated dibenzofurans (PCDFs) and 22 polychlorinated biphenyls (PCBs), including 12 dioxin like-PCBs (non- and mono-ortho PCBs) were measured in 80 sheep milk samples from farms located in an industrialized area of Sardinia, Italy. PCDDs and PCDFs mean concentrations were 2.45 and 3.69 pgg(-1) fat basis, respectively. The mean dl-PCB concentration was 2.01 ngg(-1) fat basis, while cumulative ndl-PCB levels ranged from 1.02 to 20.42, with a mean of 4.92 ngg(-1) fat. The results expressed in pg WHO-TEQ/g fat showed that contamination level of milk was below the limit values for human consumption established by EC legislation. In the same way, all the investigated milk exhibited PCDD/Fs concentrations below EU action levels, while dl-PCBs concentrations exceeded the action level of 2.0 pg WHO-TEQ/g fat. These findings point to the need to continue to conduct general monitoring programmes, including also milk samples from areas not close to the contaminant-emitting industries, in order to better evaluate the impact of industrial activities on surrounding environment.

    ABSTRACT: The most popular brands of salted anchovies (Engraulis encrasicolus) from the Mediterranean Sea and Atlantic Ocean were purchased from several Italian supermarkets and grocery stores. Heavy metal (Hg, Cd, and Pb) and polychlorinated biphenyl (PCB) levels were determined and assessed by comparing the concentrations in these samples with the maximum permissible limits set by the European Union (Reg EC 629/2008 and Reg EC 1881/2006 [Off. J. Eur. Union L 173:3-9 and 364:5-24, respectively]). The Hg and Cd levels were higher than those of Pb in all samples examined. For Hg and Pb, the concentrations recorded in this study were below the authorized limits, while an appreciable percentage of samples from both locations (Mediterranean Sea, 35%, and Atlantic Ocean, 25%) showed Cd levels exceeding the threshold recommended for human consumption. Concerning PCBs, the results of principal component analysis showed that samples from the two different marine areas appeared to be discriminate, with Mediterranean anchovies more contaminated than the others, in spite of their lower lipid content. However, anchovy samples from both locations had dioxinlike-PCB levels (Mediterranean Sea, 0.011 pg World Health Organization toxic equivalency [WHO-TEQ] g(-1), wet weight, and Atlantic Ocean, 0.007 pg WHO-TEQ g(-1), wet weight) that were below the WHO-TEQ maximum concentration set by European regulation. The results of this study will help in generating data needed for the assessment of heavy metal and PCB intake from this food.

    ABSTRACT: Liver of blue shark (Prionace glauca) specimens from the South-Eastern Mediterranean Sea were analyzed for the presence of polychlorinated biphenyls (PCBs), including coplanar congeners, polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs). PCBs were the dominant chemicals, followed by PCDFs and PCDDs. The pattern of PCB congener concentrations in the hepatic tissue was dominated by higher chlorinated compounds. The specific profile of toxic PCDD/F congeners was characterized mainly by 2,3,7,8-TCDF and 2,3,7,8-TCDD, followed by 1,2,3,6,7,8-HxCDD and 2,3,4,6,7,8-HxCDF. The total 2,3,7,8-TCDD toxic equivalent (TEQs) was 149 pg g⁻¹ lipid wt. The profile of TEQ shows that PCDDs present the greatest risk to this species contributing to total toxicity with a percentage approximately of 60%, while the contribution of PCDFs and DL-PCBs is almost the same being 22.4% and 21.6%, respectively. Further investigations are urgently needed to characterize the PCDD/Fs contamination levels not only in elasmobranch fish but in all Mediterranean marine biota.

    ABSTRACT: Polychlorinated biphenyls (PCBs), polychlorodibenzo-p-dioxin (PCDDs) and polychlorodibenzofurans (PCDFs) were determined in the muscle tissue of Polyprion americanus (wreckfish) from the Adriatic Sea (Mediterranean Sea). PCB concentrations ranged from 2 to 189 ng/g l.w. (mean: 92 ng/g l.w.), while PCDD/F levels were between 1 and 3 pg/g l.w. (mean: 1.9 pg/g l.w.). Among PCB congeners the most abundant compounds in all the examined samples were PCB 153 (35.9%) and PCB 138 (27.4%), while 2,3,7,8-TCDF (53.6%) and 2,3,7,8-TCDD (17.9%) were predominant among PCDD/Fs. The estimated intake (0.17 pg/TEQs/body weight/week) was well below the maximum permissible level set by WHO (14 pg TEQs/kg body weight/week).

    ABSTRACT: PCB and DDT concentrations were determined in the adipose tissue of cats and dogs from Southern Italy. In cats p,p'-DDE was the most abundant DDT component (95.0%), while in dogs these compounds were absent, except in two specimens. PCB concentrations were higher in cats (199.02 ng g(-1) lipid weight) than in dogs (41.61 ng g(-1) lipid weight). Also there were inter-specific differences in the contribution of the different congeners to PCBs, although PCB 138, PCB 153 and PCB 180 were the most representative congeners in both species. Animals from one location, Taranto City, had significantly elevated concentrations of dioxin-like PCBs compared to the other locations. Consequently the estimated mean 2,3,7,8-tetrachlorodibenzo-p-dioxin toxic equivalents (TEQs) of coplanar PCBs were higher in these animals (cats: 0.65 pg g(-1) lipid weight; dogs 0.29 pg g(-1) lipid weight) than in the other ones (cats: 0.12 pg g(-1) lipid weight; dogs: 0.001 pg g(-1) lipid weight).

    ABSTRACT: Muscle tissue of bluefin tuna (Thunnus thynnus) was analysed for PCBs to ascertain whether the concentrations exceeded the levels fixed by the European Commission and whether this fish was suitable for human consumption. PCB concentrations were comprised between 96 and 6571 ng/g l. w. (mean: 764 ng/g l.w.). Isomer-specific analysis revealed a profile dominated by hexa- (65.4%) and pentachlorobiphenyls (18.0%), followed by hepta- (15.4%) and tetrachlorobiphenyls (1.2%). The dietary intake was below the limit of 14 pg TEQs/kg body weight/week set by European Commission. The results obtained are not to underestimate, considering that the daily intake do not include other food which might also pass these contaminants to man.

    ABSTRACT: Polybrominated diphenyl ethers (PBDEs) were investigated in 15 composite liver samples from two deep-sea fish species, the hollowsnout grenadier (Trachyrinchus trachyrinchus, TT) and the roughsnout grenadier (Coelorhynchus coelorynchus, CC). Mean concentrations of sum tri- to hepta-BDEs were higher in CC species than in the TT species (16.9 vs. 4.5 ng/g lipid weight (lw), respectively). BDE 47 and BDE 100 were the major congeners in both species. Methoxylated PBDEs (MeO-PBDEs), reported as being naturally produced in marine environments, were also measured in all samples. Similar to those of PBDEs, mean concentrations of sum MeO-PBDEs (sum congeners 2'-MeO-BDE 68 and 6-MeO-BDE 47) were higher in the CC species (28.9 vs 6.6 ng/g lw, respectively). Interestingly, polybrominated hexahydroxanthene derivatives (PBHDs) had the highest contribution to the total load of organobromines in the deep-sea fish samples. Contraryto those of PBDEs and MeO-PBDEs, the mean concentrations of PBHDs were higher in the TT species (7040 vs. 530 ng/g lw, respectively). Furthermore, an unusual profile was seen in the TT species, for which a tetrabrominated BHD isomer was the predominant isomer (up to 98% of the sum PBHDs). This differs from the profiles of PBHDs dominated by a tribrominated BHD isomer reported until now in the literature. The mixed halogenated monoterpene (MHC-1) and 2,4,6-tribromoanisole (TBA) were detected as well, albeit at lower concentration (<5 ng/g lw), supporting the hypothesis that these two natural products are rather abundant in shallow waters.

    ABSTRACT: The muscle tissue of eel (Anguilla anguilla) was analysed for polychlorinated biphenyl (PCBs) to ascertain whether the concentrations exceeded the maximum levels fixed by the European Commission and whether the examined samples could be considered suitable for human consumption. Average contamination levels were 86 ng/g wet wt. Isomer-specific analysis revealed a profile dominated by hexa- and pentachlorobiphenyls, followed by heptaand tetrachlorobiphenyls. The mean PCB concentrations, calculated as the sum of the seven “target” congeners indicated by the European Commission, exceeded the established limit, while the dietary intake was below 8 pg TEQs/kg body weight/week recently set by European Commission.

    ABSTRACT: This study investigated the subcellular distribution of Cd, Cu and Zn in liver and kidney of green turtles (Chelonia mydas) stranded along the Italian coast of the South Adriatic Sea (Eastern Mediterranean). Cd and Zn mean concentrations did not differ significantly between liver (4.26microgg(-1) and 34.53microgg(-1), respectively) and kidney (5.06microgg(-1) and 26.39microgg(-1), respectively), whereas the levels of Cu were significantly higher in liver (32.75microgg(-1)) than in kidney (8.20microgg(-1)) (p<0.009). Most of Cd, Cu and Zn was present in hepatic and renal cytosol, and their concentrations increased with total levels in both organs, indicating that cytosol has a crucial role in metal accumulation. Cd and Cu in hepatic and renal cytosol were present mostly in metallothionein fractions (MTs), whereas Zn was fractionated into MTs and high-molecular-weight-substances (HMWS). The comparison with the results of other investigations on individuals of the same species collected in different marine areas shows good agreement relatively to essential metals. For Cd our data are comparable with those encountered in specimens from the Mediterranean Sea (Cyprus) confirming the homogeneity of the area comprising the south-eastern basin of the Mediterranean Sea from an ecological point of view.

    ABSTRACT: Polychlorinated biphenyl (PCBs) residues in the muscle tissue of Mugil cephalus and Mullus surmuletus have been determined in order to evaluate the risk for humans, resulting from the consumption of these marine species. Contamination levels were 1210 μg/kg lipid wt for M. cephalus and 252 μg/kg lipid wt for M. surmuletus. Isomer-specific analysis revealed a profile dominated by hexa- and pentachlorobiphenyls. The dietary intake was below to 8 pg TEQs/kg body weight/week recently set by European Commission. To educate the consumer to chose fish with low lipid content and of little size may constitute a valid tool to reduce the exposure risk to these contaminants.

    ABSTRACT: Polychlorinated biphenyl (PCBs) residues were tested in 137 (45.5%) of the 301 samples of raw milk in order to evaluate the risk for consumers. PCBs found varied from 0.25 to 72.52 μg/kg (aver.: 7.18 μg/kg). Predominant was the presence of PCB 95 and PCB 52, which were detected in 70.8% and 32.8% of the samples, respectively. Among the PCBs “dioxin-like“, non- and mono-ortho substituted, was present solely PCB 118, which was observed only in five samples in modest amount, comprised between 1.62 and 4.57 μg/kg (aver.: 2.52 μg/kg). The results highlight that the hygienic-sanitary aspect of the milk analysed is satisfying.

    ABSTRACT: Polychlorinated biphenyl (PCBs) residues in the muscle tissue of Arnoglossus laterna and Lepidorhombus whiffiagonis have been determined in order to evaluate the risk for humans, resulting from the consumption of these marine species. PCBs concentrations were 281 μg/kg for A. laterna and 409 μg/kg for L. whiffiagonis. Isomer-specific analysis revealed a profile dominated by hexa- and pentachlorobiphenyls. PCB dietary intake was below to 8 pg TEQs/kg per weekly recently set by European Commission. The results obtained are not to underestimate, considering that the weekly intake do not consider other food which might pass these contaminants to man.

    ABSTRACT: Cadmium and mercury concentrations were measured in the flesh and hepatopancreas of different species of cephalopod molluscs (European squid, common octopus, curled octopus, horned octopus, pink cuttlefish, common cuttlefish) in order to establish whether the concentrations exceeded the maximum levels fixed by the European Commission. In hepatopancreas, the levels of cadmium were substantially higher than those in flesh (flesh 0.11-0.87 microg g(-1) wet weight, hepatopancreas 2.16-9.39 microg g(-1) wet weight), whilst the levels of mercury (flesh 0.13-0.55 microg g(-1) wet weight, hepatopancreas 0.23-0.79 microg g(-1)) were approximately double those in flesh. Concentrations exceeding the maximum permitted limit of cadmium were found in 39.8 and 41.0% of common octopus and pink cuttlefish flesh, respectively. For mercury, concentrations above the limit were found only in octopuses, and precisely in 36.8, 50.0 and 20.0% of flesh samples of common, curled and horned octopus, respectively. In the hepatopancreas, concentrations of cadmium and mercury were above the proposed limits in all the samples examined. The estimated weekly intake of between 0.09 and 0.49 microg kg(-1) body weight for cadmium and between 0.05 and 0.24 microg kg(-1) body weight for mercury made only a small contribution to the provisional tolerable weekly intake (cadmium 1.3-7.0%, mercury 1.0-4.8%) set by the WHO.
