主 题：PAHs food chain water sediment Euphrates River
摘 要：The Euphrates River is one of the major rivers in Iraq. When it reaches north of Hilla city, it will be divided in two branches. One of these braches flows toward Hilla city. On this branch, six locations were studied for the water quality of the Euphrates water. The present paper is aimed to fill the gap of information of the presence of PAHs （poly aromatic hydrocarbons） in water and sediment of AI-Hilla River, as well as to determine the quality and quantity of some PAHs. The depth of the river ranges from 2 m to 6 m. The quality, quantity and the origin of PAHs were studied in the water and sediment of Al-Hilla River. In addition, some physical and chemical properties were studied at six sites along the studied area, for the period March, 2010 to February, 2011. Sixteen PAHs that are listed by USEPA （US Environmental Protection Agency） as priority pollutants （Nap （naphthalene）, Acpy （acenaphthylene）, Acp （acenaphthene）, Flu （fluorine）, Phen （phenanthrene）, Ant （anthracene）, Flur （fluoranthene）, Py （pyrene）, B（a）A （benzo（a）anthracene）, Chry （chrysene）, B（b）F （benzo（b）fluoranthene）, B（k）F （benzo（k）fluoranthene）, B（a）p （benzo（a）pyrene）, BbA （dibenzo（a,h）anthracene）, B（ghi）P （benzo（ghi）perylene） and Ind （indeno （1,2,3-cd） pyrene）） were detected in Al-Hilla river. High concentrations of PAHs were detected in the sediment relative to that within the water. The present study revealed that the origin of PAHs in water and sediment might be the pyrogenic origin.
