Abstract

A Marine Oil Pollution Index (MOPI) is presented to characterize the hydrocarbon burdens of marine tissues or sediments. The index incorporates the ratios of unresolved to resolved components, even n-alkanes to odd n-alkanes, and branched hydrocarbons to n-alkanes, plus the total recoverable aliphatic and aromatic hydrocarbon concentrations from gas chromatographic analysis, to yield a single value that can be used to compare the relative magnitude of oil contamination in a series of tissue or sediment samples. Several examples of tissue samples from the intertidal mussel Mytilus californianus are presented, along with results from the 1975-78 BLM Southern California Baseline Study and MMS-sponsored Georges Bank Monitoring Program, to demonstrate the usefulness of generating single index values for time-series or spatial trend analyses. MOPI values calculated for analyzed tissue samples reflect varying degrees of exposure, ranging from pristine to heavily petrogenic conditions. A MOPI value calculated for a drilling fluid sample containing diesel oil residues also reflects the heavily petrogenic contamination.

海洋油污指数

提出了海洋油污染指数(MOPI)来表征海洋组织或沉积物的碳氢化合物负荷。该指数结合了未解析组分与已解析组分、连正构烷烃与奇数正构烷烃、支链烃与正构烷烃的比值，再加上气相色谱分析得出的总可回收脂肪烃和芳烃浓度，从而产生一个单一的值，可用于比较一系列组织或沉积物样品中油污染的相对程度。本文介绍了潮间带贻贝(Mytilus californianus)的几个组织样本，以及1975-78年BLM南加州基线研究和mms赞助的乔治银行监测计划的结果，以证明生成单一指标值对时间序列或空间趋势分析的有用性。为分析的组织样本计算的MOPI值反映了不同程度的暴露，从原始到严重含岩条件。对含有柴油残留物的钻井液样品计算的MOPI值也反映了严重的岩石污染。
