@Article{, title={Bioaccumlation Of Total Petrolum Hydrocarbons In Pseudodontopsis euphraticus And Bellamya bengalensis , In Euphrates River , Al-Nassiriyah City / Iraq.}, author={QASIM MOHAMMED AL-TAHER and MANAL MOHAMMED AKBAR and IMAD HADI Al-QAROONI}, journal={Journal of Basrah Researches (Sciences) مجلة ابحاث البصرة ( العلميات)}, volume={46}, number={2}, pages={115-127}, year={2020}, abstract={The current study was conducted for a full year (from December 2018 to November 2019) to study and determine the concentration of total petroleum hydrocarbons in the soft tissues of two species of Molluscs Snails Bellamya bengalensis and Clams Pseudodontopsis euphraticus whose samples were collected from four stations located on the Euphrates River in the city Nasiriyah, southern Iraq. The total petroleum hydrocarbon concentration was calculated in B. bengalensis, P. euphraticus, water and sediments using an ultra violet fluorescence apparatus, as it was found through the study that the highest concentration was recorded during the winter and the lowest during the summer, and the range from the average concentration of total hydrocarbons in B. bengalensis (1.52-12.96) µg /g dry weight , P. euphraticus (16.69 -1.46) µg/g dry weight , water (8.43-31.28) µg/l and for sediments(205-118) µg/g dry weight. The second and third stations also recorded the highest concentration .The lowest concentration levels in the first and fourth stations. It was noticed through the results that there is a seasonal and local variation in the concentration of total oil hydrocarbons in water, sediments and living organisms in the Euphrates river, as it was found that the highest concentration rate in the sediments followed by water, then P. euphraticus and B. bengalensis, was a percentage the TPHs in the study area are within the global and Iraqi determinant.
