Analysis of dioxins, furans and DL-PCBs in food and feed samples from Lithuania and estimation of human intake

The methods, validated for determination of dibenzo-p-dioxins, dibenzofurans and dioxin like-polychlorinated biphenyls were applied for investigation of food and feed matrixes. Validation criteria on repeatability and reproducibility conditions comply with the requirements of European Commission. Validated methods were successfully applied for determination of PCDD/F and DL-PCB in fish, meat and feed using HRGC–HRMS. Statistical data was evaluated. One focal point of this work was to determine a fit for dioxins, furans and DL-PCBs of fatty fish for human consumption from the Baltic Sea ICES 26. Daily intake was found to be in the range of 2–4 TEQ pg/kg body weight and it is in the range of recommended TDI of 1–4 TEQ pg/kg body weight. The range of Baltic cod liver was 2–4 pg TEQ kg bw−1 d−1 WHO-TEQ(1998) PCDD/F, PCB and its consumption was forbidden in Lithuania in 2011. Baltic fish represents 97.9% of human daily intake. Other matrixes like meat, eggs and feed did not exceed the maximum limit set by EU during the period of 2005–2011.
