Bibliography

Provides a procedure for the determination of polychlorinated dibenzo-[roh]-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), (together termed 'dioxins') and dioxin-like and non dioxin-like PCBs (dl-PCBs and ndl-PCBs) in animal feeding stuffs. Collaborative studies have been carried out. The method is suitable for the determination of dioxins, dl-PCBs and ndl-PCBs at the appropriate MRL in compound feed and ingredients e.g. oil, mineral clay. The method is applicable to samples containing residues of one or more of the following dioxins, dioxin-like PCBs and indicator PCBs. The limit of quantification (LOQ) for the relevant individual congeners of dioxins/furans is 0,05 pg/g (OCDD/F = 0,1 pg/g), of non-ortho PCBs 0,05 pg/g, of mono-ortho PCBs 10 pg/g and of indicator PCBs 100 pg/g.
