| Abstract | ||
| The study was carried out on gold fish Carassius auratus to determine the bioaccumulation of petroleum hydrocarbons in different tissues ( livers , gills and muscles ) exposed to sub lethal effects . Experiments were conducts in out-doors basin size (2x1x1) m3 and filled with fresh water containing (1200) letter. One of three concentrations of Basrah crude oil (1.2 , 2.4 ,3.6) letter was added to each basin besides control while three of the remaining basins were used for restoring process. Bioaccumulation for petroleum hydrocarbons were determined for livers, gills and muscles of fish exposed in three concentrations used besides control after exposure period of (12,4) days during winter and summer seasons respectively using spectroflourometer . Fat were determined in different tissues for winter and summer period . Livers and gills tissues were shown the highest values of accumulation for petroleum hydrocarbons, while muscles tissues recorded the lowest value . The results shown that the bioaccumulation values in summer seasons were higher than winter . Restoring processes shown a sharp decline of petroleum hydrocarbons in the levels of bioaccumulation in different tissues of fish exposed after transferred to clean water for (7) days compared with those exposed directly . . | ||
