molecular weight compounds which decreased relative to less volatile 

 n-alkanes (e.g., C-24) in the 8h and 48h weathered oil. Octane and 

 other compounds of similar volatility were nearly depleted after 48h of 

 evaporative weathering. Figure 10 shows the aromatic fractions of each 

 of the oils used. After 8h of evaporative weathering, toluene and sev- 

 eral other volatile aromatic compounds were significantly reduced, and 

 after 48h most of the predominant volatile aromatics were evaporated.
