Abstract:

This study was conducted in Iraqi marine waters, It include 10 species of fishes and two species of shrimps ,sample were collected extent to ( 18 ) month in the period of May, 2010 to September, 2011 . The concentration of total petroleum hydrocarbon were determined spectroflourometrically and the mean concentration of total petroleum hydrocarbons in fish samples were in Otolithesruber muscles varied between ( 1.44 ) μg/gd.w. in September 2011 and ( 31.15 ) μg/gd.w. in July 2010 and in Johnieopssina muscles between ( 4.14 ) μg/gd.w. in January 2011 and (38.69) μg/gd.w. in May 2010 and in Tenualosailisha muscles between ( 1.72 ) μg/gd.w. in May 2011 and ( 54.46 ) μg/gd.w. in May 2010 and in Nematalosanasus muscles between ( 3.28 ) μg/gd.w. in January 2011 and ( 30.01 ) μg/gd.w. in July 2010 and in Synapturaorientalis muscles concentrations varied between ( 4.06 ) μg/gd.w. in May 2011 and  ( 37.11 ) μg/gd.w. in July 2011 and in Alepesmelanoptera muscles between (7.33) μg/gd.w. in November 2010 and (31.58) μg/gd.w. in May 2010 and in Scomberomoruscommerson muscles concentrations varied between ( 0.23 ) μg/gd.w. in January 2011 and ( 31.72 ) μg/gd.w. in May 2010 and in Chirocentrusnudus muscles between ( 6.34 ) μg/gd.w. in November 2010 and ( 35.65 ) μg/gd.w. in May 2011. and in Pampus argenteusmuscles concentrations varied between ( 10.82 ) μg/gd.w. in September2011 and (31.22) μg/gd.w. in July 2011 and in Liza subviridis muscles between (2.29 ) μg/gd.w. in January 2011 and ( 31.01 ) μg/gd.w. in July 2010 . and in Acanthopagrus latus muscles concentrations variedbetween (1.29 ) μg/gd.w. in May 2011 and ( 29.02 ) μg/gd.w. in July 2010 . In shrimpMetapenaeusaffinis concentrations variedbetween ( 9.11 ) μg/gd.w. in January 2011 and ( 21.06 ) μg/gd.w. in July 2011 and in shrimpThenusorientalis between ( 3.57 ) μg/gd.w. in January 2011 and ( 36.26 ) μg/gd.w. in July 2010 . The present study T. ilisha was occur high ability to accumulate hydrocarbons in muscles compared with other fishes.
