Abstract
Five different fish samples (mackerel (Scomber scombrus), tilapia (Oreochromis niloticus), croaker (Micropogonias unduletus), herring
(Clupea harengus), horse mackerel (Trachurus trachurus) and blue whitting (Micromesistus pontassou)), fresh and smoked, bought from
Mushin market in Lagos State, Nigeria, were sampled for polycyclic aromatic hydrocarbon (PAH) contaminants. The levels of PAHs
ranged from 0.004 g/kg for acenaphthene in dry M. pontassou to 2.275 g/kg for phenathrene in dry S. scombrus. Florene, phenathrene,
anthracene and fluoranthene were detected in all the fish samples. Indeno (123) perylene, dibenzo (ah) anthracene and benzo (ghi)
perylene were not found in any of the fish samples. Smoking increased the levels of PAHs in the fish samples. These results show that
PAH levels in the fish samples are higher than the permissible limit set by the World Health Organization (WHO) and the Agency for
Toxic Substances and Disease Registry (ATSDR). The implications of these contaminants in the environment together with their associated
health hazards are also examined.
