Building a database to identify oil sourcesin oil pollution incidents in Vietnam
Abstract
Oil source identification was performed according to the method of comparing analysis results of spilled oils and suspected sources. The analysis results are based on the distribution characteristics of n-alkane, polycyclic aromatic hydrocarbons and biomarker compounds, then diagnostic ratios are calculated based on these distribution characteristics.
The oil source identification database was built by the Research and Development Centre for Petroleum Safety and Environment (Vietnam Petroleum Institute) for crude oils from fields in Vietnam and some imported crude oils. The identification database for each type of crude oil includes the chromatogram, 25 major diagnostic ratios following CEN/TR 15522-2:2012 standard, and 4 reference ratios for Southeast Asian crude oils.
The oil source identification database is a valuable reference to facilitate rapid identification of the suspected sources which cause pollution and help limit the number of analysis samples, thus saving time and costs. It is also one of the important scientific bases in the process of investigating and establishing evidence to penalise and requesting compensation for damages in oil spill incidents.
