Summary
Background: The aim of this study was to determine 17 Polychlorinated Dibenzo-p-dioxin and Dibenzofuran (PCDD/F) and 12 Dioxin-like Polychlorinated Biphenyl (DL-PCB) concentrations in the tissues of Finnish terrestrial herbivore species, semi-domesticated reindeer (Rangifer tarandus tarandus L.), an...
