文摘
A field bioremediation assay using the oleophilic fertilizerS200 was carried out 10 months after the Prestigeheavy fuel-oil spill on a beach of the Cantabrian coast(North Spain). The field survey showed that S200 significantlyenhanced the biodegradation rate, particularly of highmolecular weight n-alkanes, alkylcyclohexanes, and benzenes,and alkylated PAHs, paralleling the results previouslyfound in vitro. The most significant molecular bioremediationindicators were the depletion of diasteranes and C-27sterane components. Enhanced isomeric selectivity wasalso observed within the C1-phenanthrenes and dibenzothiophenes. Through the analysis of some target aliphaticand aromatic hydrocarbons a number of chemicalindicators for assessing the efficiency of field bioremediationas well as identifying the source of highly weatheredsamples collected in the area after the spill are defined.
