sPCA Standard 
(C, 0 -C,v 55.5% Cl content) 
Figure 15: Formula group patterns of sPCAs (Ci 0 -Ci 3 ) in selected samples from the Lofot Island (Al), the Baltic Sea (OS1, OS3, OS4) and the North Sea 
(NS1-NS3). The patterns for mPCAs (C14-Q5) are quite similar and are therefore only shown for the selected samples to the left. Two standard mixtures are 
shown for comparison (sPCA: C10-C13, 55.5 % chlorine content, mPCA: C14-Q7, 52 % chlorine content). Determination was carried out by ECNI.
