ASSESSMENT OF LEVELS OF POLYCYCLIC AROMATIC-HYDROCARBONS IN THE OIL FROM KUWAIT OIL LAKES

In an attempt to assess the potentials impacts resulting from the oil fires started during the Gulf War, levels of polycyclic aromatic hydro carbons (PAHs) were determined in Kuwaiti oil lakes. Samples were coll ected from two oil lakes within each of the four oil fields heavily da maged during the 1991 Gulf War. The oil samples were fractionated and the aromatic fraction analyzed quantitatively by gas chromatography/ma ss spectrometry (GC/MS). In addition, the effect of weathering on the PAH content was monitored over a 21-month period. The results indicate d that total PAH contents initially ranged from 52.4 to 425.7 mg/kg in oil lakes. Phenanthrene and chrysene were the major PAHs in most of t he samples. Benzo(a)pyrene was detected in all samples in varying amou nts (0.46 to 5.3 mg/kg). Total PAH contents were higher, after 21 mont hs, ranging from 59.55 to 616.9 mg/kg. Concentration of benzo(a)pyrene also increased considerably (from 0.16 to 22.2 mg/kg). The hazard pot ential of these compounds in Kuwait's environment was assessed and ind icated that large amounts of the remaining oil will continue to have s erious ecological implications unless immediate measures are taken to deal with the problem.
