Research paper thumbnail of Congener Specific Analysis of Polychlorinated Dibenzo- p -dioxins and Dibenzofurans in Crabs and Sediments from the Venice and Orbetello Lagoons, Italy

On average, 95 PCB congeners were detected in whole blood samples. The mean of total PCB concentration in whole blood was 771.9 pg g )1 whole blood (139.6 ng per g-lipid). Congener-specific analysis identified the predominant PCB congeners as #153 (22.2%), #180 (11.6%), #138 (8.4%), #182/187 (6.6%), #118 (5.6%), #163/164 (5.0%), #99 (3.9%), #74 (3.6%), #146 (3.3%), #170 (3.0%) and #156 (2.2%), representing 75.6% of all PCBs detected in the human blood samples. Among the predominant PCB congeners, #153, #180, #138, #187 #118, #99 and #74 had chlorine as the substituent at the 2-, 4-and 5-positions of the phenyl-ring. In human blood in Japanese individuals, it is assumed that these congeners would be characteristic of the entire population, based on the relation between PCB ingestion and metabolism. Measuring 209 PCB congeners has the advantage of providing detailed information regarding the congener distribution within the blood samples, which can be compared to congener patterns in other matrices. Congener-specific analysis of 209 PCB congeners is especially useful in evaluating human exposure to PCBs.

Research paper thumbnail of Evaluation of 2,3,7,8 specific congener and toxic potency of persistent polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans in cetaceans from the Mediterranean Sea, Italy

Liver samples of a variety of cetaceans species found stranded along the Italian coasts during the period of 1987-1992 were analyzed for PCDDs and PCDFs. The main aims were to scrutinize levels and patterns of PCDDs and PCDFs for the first time in cetaceans from the Mediterranean Sea and to estimate whether chlorinated compounds mentioned are implicated in the exceptionally high mortality of dolphins that occurred in the Mediterranean Sea during 1990-1992. PCDD and PCDF profiles were dominated by congeners OCCD and OCDF. The new toxic equivalency factors recommended by WHO in 1997 were used for calculation of dioxin-like toxicity. On the basis of our previous study of PCBs, the overall TEQ calculated from the 2,3,7,8substituted PCDDs and PCDFs do not contribute as much dioxin-like toxicity as PCBs.
