Table 38: Concentrations of chlordanes [ng/g dry weight respective in ng/g TOC] for sediments from the 
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 39: Concentrations of sPCAs und mPCAs in surface water in Germany (WFIO, 1996) 126 
Table 40: Composition and source of the sPCA and mPCA reference mixtures employed for 
quantification or for composition characterisation 130 
Table 41: Manufacturer and concentrations chlordane solutions used for quantification. The purity was 
>99 % except for MC8 and 4,5-dichlorchlordene 132 
Table 42: Mass-to-charge ratios of the [M-Cl]" ions (abbreviated as X in the table) of the two most 
abundant isotope signals of sPCA and mPCA congeners used for quantification and 
identification in the ECNI-MS mode 136 
Table 43: Mass-to-charge ratios of ion selected for the internal standards e-HCH and 13 Q 0 -trans- 
chlordane as well as for other polychlorinated compounds included during method 
development. The ECNI-MS mode was applied 137 
Table 44: Selected precursor and product ions for the determination of the total PC A content by EI- 
MS/MS with an ion trap and triple quadrupole mass spectrometer. Important instrument 
parameters and the masses for the internal standard ’C1 0 -rrc//?,v-chIordane are also given 140

identification in the ECNI-MS mode 142 
Table 46: Selected precursor and product ions for the determination of selected chlordanes by EI-MS/MS 
with a triple quadrupole mass spectrometer. Important instrument parameters and the masses for 
the internal standard 13 Cio-frani-chlordane are also given 143 
Table 47: Average molar mass and average chlorine content of PC As present in fish liver from the North 
and Baltic Sea and of the reference standards used for quantification according to Tomy et al. 
(1997). ECNI was applied for determination 144 
Table 48: C H4/C H2CI2-NICI-M S determination of average molar mass and average chlorine content of 
PCAs present in sediments from the Baltic and North Sea and of the reference standards used 
for quantification (see Tomy et al. (1997)). This procedure required sediments with levels >50 
ng/g dw 145 
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 
Table 50: Survey over analysed biota from the northern North Atlantic and Bear Island. Sampling sites: 
Cod (Gadus morhua) from NW Europe, Arctic char (Salvelinus alpinus) and seabirds (little 
auk: Alle alle, kittiwake: Rissa tridactyla, glaucous gull: Larus hyperboreus) from the Arctic 
Bear Island (Lake Ellasjpen). Information is also given about the applied methods for the 
determination of PCAs 147
