Polychlorinated biphenyls (PCB), dibenzo-p-dioxins (PCDD) and dibenzofurans (PCDF) in human milk from three geographic areas in Norway.

32 samples of human breast milk taken in winter 1985/86 in three regions were analyzed for PCB, PCDD and PCDF. Study design and analytical procedures are described. No regional differences in PCB or toxic PCDD/ PCDF equivalent were found. Several PCDFs were higher in one region. All detected concentrations rank between the medium levels found in other countries.
