Concentrations of polychlorinated dibenzo- p-dioxins (PCDDs), dibenzo- p-dioxins (PCDFs) and dioxin-like coplanar PCBs and 2,3,7,8-tetrachlorodibenzo- p-dioxin equivalents (TEQs) were measured in domestic animal related samples such as feed ingredient, mixed feed and animal fat from Japan. The mean concentration of total PCDDs, PCDFs and coplanar PCBs in fish oil was 17 000 pg g −1 lipid wt, which 9- to 30-fold greater than that from other animal originated ingredients. Mixed feed for chicken and chicken fat contained greater total PCDDs, PCDFs, coplanar PCBs concentrations (190 and 2100 pg g −1 lipid wt) compared to those for pig (120 and 320 pg g −1 lipid wt). WHO-TEQs were ranged 0.39–13, 0.15–0.22 and 0.73–2.8 pg g −1 lipid wt for ingredients, mixed feeds and animal fats, respectively. Greater biomagnification factor was noticed for congeners 1,2,3,7,8-PeCDD, 1,2,3,6,7,8-HxCDD, 2,3,7,8-TCDF and 1,2,3,4,7,8-HxCDF in chicken and pig fat. Biomagnification factors for both mono- and non- ortho coplanar PCBs were greater in chicken fat compared to those in pig fat.
