North and Baltic Sea. The internal standard 4,5-DCCD was not added to the samples of 2002.
Therefore, frans-nonachlor, which elutes in the fractions FI and F2 was not quantifiable 123

Table 49: Survey over analysed fish samples (cod: Gadus morhua, flounder: Platychtus flesus, North Sea
dab: Limanda limanda) from the North and Baltic Sea. EI-MS/MS was applied for screening
and ECNI-MS for quantification of PCAs and chlordanes. Only sample NS1 was analysed by
CH4/CH2CI2-NICI as part of method development 146

Bear Island (Lake Ellasjpen). Information is also given about the applied methods for the
determination of PCAs 147
