Abstract

Samples of frozen fish available in Kirkuk markets Shad Tenualosa ilisha (Hamilton), Mackerel Trachurus trachurus (Linnaeus), Rainbow trout Oncorhynchus mykiss (Walbaum) and striped catfish (Pangasianodon hypophtholmus (Sauvage). They collected for the period 1st May 2015o 30th January 2016 at weights average between 650-1250 g. The results showed many of carcinogenic and non-carcinogenic hydrocarbons compounds; Rainbow trout contained seven and nine of hydrocarbons compounds in the extracts of hexane and ethanol respectively, among them, there were five carcinogenic hydrocarbons in the ethanol extract and three in the hexane, their values ranged between 0.234-19.707 and 0.419-2.972 ng.g-1 dry weight respectively. Numbers of the hydrocarbons ranged between 4-6 in other fish species. This may due to the differences of nature of feeding among the fish species and the differences in their fat content. In Shad fish, the results have recorded one carcinogenic compound in the ethanol and five in the hexane, the concentration of Benzo (a) pyrene reached 24.23 ng.g-1 dry weight which is the most dangerous component among carcinogenic compound. Mackerel containsive compounds of hydrocarbons in the hexane; Four of them belong to the non-carcinogenic group and sixn ethanol, ive of them are non- carcinogenic. This study showed that differences in the numbers and concentrations of aromatic hydrocarbons in the studied fish. This is  due to several reasons such as occurrences of fish near to the sources of hydrocarbons pollution the nature of fish feeding and living.
