Volatile Organic Compounds (VOCs) and Polycyclic Aromatic Hydrocarbons (PAHs) in the Water-Soluble Fraction (WSF) of Kerosene and Aviation Fuel in Seawater
Detailed compositions of the water-soluble fraction (WSF) of kerosene and of aviation turbine kerosene (aviation fuel) were investigated. WSF was prepared by stirring kerosene and aviation fuel for 24 hrs with seawater. Three different temperatures (15o, 25o and 35oC) were used during the preparation. Volatile organic compounds in the WSFs were analyzed by purge & trap/GC and PAHs were determined in the concentrated extract by GC/MS in single ion monitoring mode. The results showed that WSF of kerosene contained 30 volatile organic compounds the total of which amounted to about 7 mg/l. Aromatics and naphthenes were the dominant groups. The concentration of VOCs in the WSF of aviation fuel was slightly less than kerosene (about 5 mg/l) but contained more compounds (39 compounds). VOCs consisted, almost entirely, of aromatic compounds. There were, however, significant differences, in the distribution and quantity of PAHs in the WSFs. The levels were relatively low (0.132 mg/l) in the WSF of kerosene. The WSF of aviation fuel, on the contrary, contained relatively large amounts of PAHs (about 4 mg/l). Naphthalene and its methylated homologs were the dominant PAHs in the WSF of both refined products.
