Two different samples of shells were collected from some locations distributed along Toubrouk City coast (Libya). The shell samples including (Patella S.p and Monodenta S.P.). The poly aromatic hydrocarbons which obtained and detected by GC-Mass instrument in this study including (Naphthalene, Acenaphthylene, Acenaphthene, Fluorene, Phenanthrene, Anthracene, Fluoranthene, Pyrene, Benzo(a)anthracene, Chrysene, Benzo(b)fluoranthene, Benzo(k)fluoranthene, Benzo(a)pyrene, Dibenzo(a,h)anthracene, Benzo(ghi) Perylene, and indeno, (1,2,3-cd) Pyrene). The results recorded that the concentrations of PAHs in the shell samples were fluctuated as following: The contents of PHAs in the patella. Sp shell samples were ranged between (0.0024-1.5 µg/g), (0.0039-3.40 µg/g) and (0.0054- 4.11 µg/g). Whereas the contents of PAHs in Monodenta. Sp shells were ranged between (7.40 and 5.23 µg/g). The study concluded that the shell samples containing high levels of aromatic hydrocarbons which maybe indicating the contribution of the petroleum industry to these concentrations.
