Abstract:
1. A method of analyzing halogenated organic compounds, comprising the steps of: providing the following compounds 4′-fluoro-2,3′,4-tribromodiphenylether, 4′-fluoro-2,3′,6-tribromodiphenylether, 4′-fluoro-2,3′,4,6-tetrabromodiphenylether, 4′-fluoro-2,3,3′,4,5,6-hexabromodiphenylether, 2′3,3′,4,5,5′,6,6′-octabromo-2,4′-difluoro-diphenylether, 2,4,4′-trichloro-3′-fluorobiphenyl, 2′,4′,4-trichloro-3,5-difluorobiphenyl, 4-methyl-2,2′,5,6-tetrachloro-3′-fluoro-diphenylmethane, 4-methyl-2,2′,5,6-tetrachloro-3′,5′-difluoro-diphenylmethane, 4-methyl-2,2′,5,6-tetrachloro-3′,3′-difluoro-diphenylmethane, 1,2,3,7,8,9-hexachloro-4-fluoro-dibenzofuran 1,2,3,7,8,9-hexachloro-4,6-difluoro-dibenzofuran 2,3,7,8-tetrachloro-1-fluoro-dibenzo-p-dioxin 1,4,6,9-tetrachloro-2-fluoro-dibenzo-p-dioxin and 1,2,3,7,8,9-hexachloro-4,6-difluoro-dibenzo-p-dioxin; selecting at least one of the compounds; and analyzing a halogenated organic compound by using at least one of the selected compounds as intern standards or surrogate standards which together with their base compounds undergo physical, chemical and/or biological processes and are subsequently detected and/or analyzed together with the processes or separately from the processes,
