Abstract




Epidemiological studies in several countries have indicated that exposure to polynuclear aromatic hydrocarbons especially benzo(a)pyrene increases the risk of cancer. A study by the World Health Organization recommended a guideline value of 0.7ug/liter for benzo(a)pyrene in drinking water, corresponding to an excess life time cancer risk of 10-5. Benzo(a)pyrene being a component of crude oil, we studied 18 water samples from crude oil polluted Niger Delta region for the presence of this compound. The analysis was carried using a gas chromatograph coupled with ion trap mass spectrometer (GC-MS). Two – third of the studied samples were found to contain benzo(a)pyrene. The highest concentration found in samples was 4.0ug/liter.
