Résumé
Food safety is currently recognized as a global concern. POPs are among the most hazardous chemicals for human and environmental health. In this study concentration of PCDD/Fs, DL-PCBs, non dioxin like-PCBs (NDL-PCBs) and PAHs have been determined in dairy products, fish/seafood and meat using GC/HRMS. In addition samples of vegetables and cereals have been screened for 113 pesticides and quantified for 68, using HRGC/HRMS ; and samples of plant origin and of animal origin have been analysed for the content of Cd and Pb as toxic elements, and Cr, Zn and Cu as essential elements using AAS. The PCDD/Fs dietary intake ranged from 3.69 to 4.0 pg WHO-TEQ/kg bw/day for PCDD/Fs and from 6.04 to 6.68 pg WHO-TEQ/kg bw/day, if DL-PCBs were included. A recalculation of the intake to include non measured groups (based on EU data), yielded a total intake of 4.06-6.38 pg TEQ/kg bw/day for PCDD/Fs and a range of 6.59-9.98 pg TEQ/kg bw/day including PCBs. Dairy products were the main contributor to the intake of PCDD/Fs and DL-PCBs. The dietary intake of seven indicator PCBs and pesticides were of lower to comparable to the intake in EU countries respectively. The international recommended doses for essential elements are supplied by the diet. The weekly dietary intake for Cd and Pb was estimated as 4.02 and 20.4 µg/kg b.w., corresponding to 49.1 % and 81.2 % of the PTWI respectively. Bread is the foodstuff that provided the highest rate of Pb and Cd intake to adults in Ismailia city
