at the two stations. Note that the PCT fingerprints of AMOCO CADIZ and 

 TANIO oils are quite distinct (Fig. 3.6), notably in the ratios of 

 compounds 1, 2 and 5, 6. Thus it appears that PCT fingerprints offer a 

 good means to trace AMOCO oil in highly weathered samples when most 

 other identifiable molecular characteristics have been lost.
