Abstract
AbstractThe 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.
Highlights
Polychlorinated biphenyls (PCBs), dioxins, furans and derivatives of these compounds arise as by-products of many industrial processes and during uncontrolled combustion in households
Most PCDDs, PCDFs and PCBs occur in low concentrations in the environment, but chronic exposure in animals ingesting them with feed can result in their bioconcentration in the food chain
We analysed the content of PCDDs, PCDFs and polychlorinated biphenyls with dioxin-like properties (PCBs) in selected natural sorbents used in animal feed
Summary
Polychlorinated biphenyls (PCBs), dioxins, furans and derivatives of these compounds arise as by-products of many industrial processes and during uncontrolled combustion in households. Due to their origin (they are sedimentary rocks) and the high possibility of binding with metal ions in the environment, there is a risk that they may contain excessive amounts of harmful admixtures in the form of dioxins or furans and their derivatives [11,14] Their use as feed additives requires careful control in accordance with applicable EU regulations 644/2017 and 771/2017. Most PCDDs, PCDFs and PCBs occur in low concentrations in the environment, but chronic exposure in animals ingesting them with feed can result in their bioconcentration in the food chain This poses a threat to every organism above this trophic link. We analysed the content of PCDDs, PCDFs and polychlorinated biphenyls with dioxin-like properties (PCBs) in selected natural sorbents used in animal feed
