• The analysed birds had also a considerable s+mPCA burden, which was in the 
same range as for DDT-compounds, PCB and toxaphenes (see Table 28). 
However, no other study of PCA in birds is currently available for comparison. 
• s+mPCA concentrations expressed in wet weight were quite similar for liver and 
muscle from Arctic char despite a ca. six times lower lipid content of muscle. This 
is also valid for the bird samples, where the lipid content of both tissues was more 
similar (Table 26). 
• The mPCA concentrations were higher than those for sPCA in many samples 
from the Baltic Sea and in birds. No clear picture was observed for the North Sea 
and northern North Atlantic. 
Table 28: Comparison of concentrations of s+mPCA, DDT-compounds, PCBs and toxaphenes in biota 
from the European Arctic. Literature data were given in ng/g ww. Therefore, also s+mPCA levels were 
expressed similarly.
