The stability of hydrocarbon samples sorbed from water onto two types of solid phases was examined. The two solid phases, XAD-2 macroreticular resin and octadecane bonded on silica gel, were found to have a preservative effect which prevented the breakdown of sorbed hydrocarbons by bacteria. Hydrocarbons stored on these solid phases for periods of up to 100 days in the presence of an oleophilic bacterial population showed no evidence of biological degradation as indicated by changes in chromatographic pattern or degradation of a radiolabeled hydrocarbon. In contrast, hydrocarbons stored in water samples containing the same bacteria showed pronounced degradation over much shorter storage periods. The macroreticular or pore structure of the solid phases is thought to be the mechanism by which the extracted hydrocarbons are preserved from bacterial attack.
