in sediments were rather high as well (station in the Eckernforde Bight). Here, even 
endosulfan II was detected. 
6.4.3.3 Biota 
25 liver samples from three different fish species (Dab (Limancla limanda), cod (Gadus 
tnorhua) and flounder (Platichtys flesus)), which had been collected during two cruises 
in the North Sea and western Baltic Sea in 2001 and 2002, were analysed, (see Table 
94, Appendix 6.6.8) 
Endosulfan I was found in most samples in the range of 0.1 to 1.4 pg/kg ww (0.26 to 7 
pg/kg lw) with a median of 0.44 pg/kg ww (1.9 pg/kg lw). The geographical 
distribution of the samples and their concentrations are shown in Figure 43. The high 
variability of the data may be considered normal. All samples from the Baltic Sea were 
below the LOD. Because of the limited data set presently available, it is difficult to 
interpret the results with respect to possible regional patterns, species differences or 
time variability. The concentrations of endosulfan II were always lower than those of 
endosulfan I, and often below the LOD.
