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
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).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
