5.7 Appendix 2: Average molar mass and Cl content of sample 
PCAs 
Table 47 summarises the average molar mass and chlorine content of PCAs present in 
the biota OS 1-OS 15 and NS1-NS7 to enable a comparison with future data. Table 48 
gives the same survey for sediment samples. 
Table 47: Average molar mass and average chlorine content of PCAs 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.
