Abstract
ABSTRACT A state-of-the-art review is provided describing specific parameters of petroleum oils that are used by various investigators to demonstrate the presence of oil pollution in water, sediments, and biological tissues. Several representative publications are discussed with regard to the techniques used for distinguishing between petroleum hydrocarbons and organics that are of recent biological origin. The techniques include chromatographic procedures using alumina and silica gel for separating hydrocarbons from other organics, followed by instrumental methods such as gas chromatography, fluorescence spectroscopy, ultraviolet absorption spectroscopy, et al. The various oil parameters that are used to demonstrate the presence of petroleum oils are discussed, and the most effective ones are recommended. In addition, a recent study is also described in which several of the parameters were used to demonstrate the presence of oil pollution in sediments from a mangrove swamp in Puerto Rico.
