Oil spills have drawn the attentions of the researchers for their potential threats as well as direct influences to the environment and human beings. Once oil is spilled that goes through various reactions such as biodegradation and photodegradation, so that chemical compositions of the spilled oil are changed by weathering process. Besides, those reactions produce various toxic materials. Petroleomics using ultra-high resolution mass spectrometer(UHR-MS) has emerged as a powerful technique for analyzing petroleum and its product. ESI, APPI, and APCI are the most common ionization techniques for characterization of petroleum products. Even though those are very useful techniques, there are some limitations associated with solvent selection, sample amount and clogging problem. Therefore, application of new ionization technique can be beneficial. Recently developed paper spray ionization (PSI) is fast and convenient ionization method for the direct analysis of complex mixtures with minimum sample preparation. In addition, ionization and subsequent MS analysis can be done with small amount of sample when compared with aforementioned ionization techniques. In this study, weathered oil and soil extract from Hebei Spirit oil spill site in Taean have been characterized by paper spray ionization mass spectrometry.
