The potentially toxic PAHs present in sediment samples were acenaphthene, acenaphthylene, anthracene, benz(a)anthracene, benzo(a)pyrene, benzo(e)pyrene, benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(g,h,i)perylene, chrysene, dibenz(a,h)anthracene, fluoranthene, fluorene, indeno(l,2,3-c,d)pyrene, naphthalene, phenanthrene, and pyrene. Among the 17 PAHs in the priority list of potential hazardous compounds, 7 of these PAHs are considered as potential human carcinogens, namely benzo(a)pyrene, benz(a)anthracene, chrysene, benzo(b)fluoranthene, benzo(k)fluoranthene, dibenzo(a,h)anthracene, indeno (1,2,3-c,d) pyrene. Seventeen different alk-PAHs found in high level in the sediment samples were 1-methylnaphthalene, 2-methylnaphthalene, 1,2-dimethylnaphthalene, 2,3,5-trimethylnaphthalene, 1-methylfluorene, 4-methyldibenzothiophene, 4,6-dimethyldibenzothiophene, 1-methylanthracene, 1-methylphenanthrene, 2-methylphenanthrene, 2,3-dimethyanthracene, 2-methylfluoranthene, 1-methylpyrene, 1-methylbenz(a)anthracene, 4-methylchrysene, 7,12-dimethylbenz(a)anthracene, and 7-methylbenzo(a)pyrene. Oyster, squid and fish samples collected and analyzed were found to contain relatively low level of PAHs and some alk-PAH compounds. There are 9 PAH compounds detected in the biological samples namely; naphthalene, acenaphthylene, fluorene, dibenzothiophene, phenanthrene, fluoranthene, pyrene, benz(a)anthracene and chrysene and 6 alk-PAHs; 1-methylnaphthalene, 2-methylnaphthalene, 1,2-dimethylnaphthalene, 4-methyldibenzothiophene, 4,6-dimethyldibenzothiophene, and 1-methylphenanthrene.}, pages = {11--16}, title = {Early Monitoring of Potentially Toxic Hydrocarbon Species in Sediment and Biological Samples from Southern Guimaras, Philippines After Oil spill}, volume = {59}, year = {} }
