Abstract/OtherAbstract:
The concentrations of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), as well as those of 18 polychlorinated biphenyls (PCBs), including 12-dioxin like (DL)-PCBs, were measured in foodstuffs randomly acquired in Catalonia (Spain) in November-December 2008. A total of 65 composite samples, belonging to various food groups were analyzed by HRGC/HRMS. The dietary intakes of PCDD/Fs and PCBs were subsequently estimated for four age groups of the population of Catalonia: children, teenagers, adults, and seniors, which were in turn divided according to sex. The highest dietary exposure to PCDD/Fs corresponded to fish and seafood (28.0%), dairy products (15.4%), and oils and fats (10.6%), while that of PCBs corresponded to fish and seafood (58.6%), and dairy products (8.9%). In contrast, the lowest contributions of PCDD/Fs and PCBs corresponded to vegetables, fruits and pulses. Concerning the sum of PCDD/Fs plus DL-PCBs, the current total intake expressed in pg WHO-TEQ/kg per day (0.60) showed a notable decreasing trend with respect to those found in previous surveys performed also in Catalonia in 2000 (3.51) and 2006 (1.12pg/kg per day). The current dietary intake of PCDDs plus DL-PCBs is similar or lower than that recently reported in studies performed in a number of regions and countries.
