No full textThe present study provides novel data regarding levels of polychlorinated biphenyls (PCBs) and organochlorine pesticides (DDTs) in muscle tissue of European conger eel (Conger conger) from Ionian Sea (Mediterranean Sea). The mean concentration of PCBs (891 ng g(-1) lipid weight) was higher than those of DDTs (543 ng g(-1) lipid weight). PCB pattern was dominated by higher chlorinated congeners (hexa-CBs: 69.3 %, penta-CBs: 17.2 %, hepta-CBs: 13.3 %). Regarding DDT pattern, p,p'-DDE was prevalent in all samples (85.5 %), suggesting no recent DDT input. The total 2,3,7,8-TCDD toxic equivalent (TEQs) of coplanar PCBs, including mono-and non-ortho congeners was 0.41 pg g(-1) wet weight (29.92 pg g(-1) lipid weight). The PCB and DDT levels, as well as TEQ concentrations were lower than most of the corresponding published data for fish from Mediterranean and non-Mediterranean regions, probably reflecting a moderately contaminated area
Residui di policlorobifenili (PCBs) nel tessuto muscolare di Anguilla anguilla.
No full textMuscle 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

Full text linkPolychlorinated 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)
