The difference is partly caused by an increased proportion of the mid-molecular weight congeners in the samples from Norway. The soils from southern Norway and the UK contained similar amounts of PCBs per unit area: those from northern Norway contained lesser amounts. The possible influence of long-term air-soil exchange, latitudinal fractionation processes and differences in land management practices on the observed patterns is discussed.
