Abstract


The method, validated for determination of dibenzo-p-dioxins, dibenzofurans and dioxin like-polychlorinated biphenyls, was carried out in fish and meat matrixes. Validation criteria on repeatability and reproducibility conditions complies with the requirements of the European Comission. Validated methods were successfully applied for determination of PCDD / F and DL-PCB in fish of the Baltic sea and meat. Concentrations of PCDD / F and DL-PCB were analysed in Baltic herring, salmon, sprats and cod liver. Exceedings of the maximum limit were determined in 9 of 25 Baltic herring, 2 of 9 salmon, 1 of 33 sprats and 9 of 10 Baltic cod liver samples. Concentrations in others fish and meat matrixes were in a “normal” level.

Keywords: PCDD, PCDF, DL-PCB, Baltic Sea, herring, sprat, validation
