Abstract The study aimed to assess the concentration of dioxins, furans, and dioxin-like polychlorinated biphenyls (PCBs) in natural feed additives used in animal nutrition. The research material consisted of four natural sorbents used as feed additives registered in the EU. The samples were analysed for the content of six octachlorodibenzo-p-dioxins (OCDDs) congeners, nine octachlorodibenzofurans (OCDFs) and fourteen dL-PCBs, and seven PCB congeners. Detailed analysis was performed using gas chromatography with high-resolution mass spectrometry. Analysing the results of congeners of individual sorbents, it was found that they were below the limit of detection or quantification and can be used as feed additives.
