The present study was conducted on the Euphrates river in Al-Ramadi city river during April.2021 to March, 2022. The study was included measure the concentration and distribution of some Polycyclic Aromatic Hydrocarbons (PAHs) and predict their sources in the samples of two species of aquatic plant (Ceratophyllum demersum L. and Elodea Canadensis Michx). the lowest value among PAHs was 0.33ng/gDW recorded for Naphthalene in C.demersum and the highest value of 225.5ng/g DW was for Dibenzo(a,h)Anthracene in Elodea Canadensis. The results of statistical analysis referred to non significant differences in the concentration of PAHs in both species of aquatic plants. In plant C. demersum, the concentration of 0.33ng/g Dw was obtained for 2 ring–PAHs, while the value of (388.93ng/gDW) was recorded for 5 ring-PAHs in E. Canadensis, The concentrations of PAHs in both species of clams and plants were significant among seasons with exception of Naphthalene. According to the values of the ratios (Phen./Ant, Flur/Py, BaP/BghiP and LMW-PAHs/HMW-PAHs), the distribution of PAHs in aquatic plants may have the origin from different sources (Pyrogenic, Petrogenic and urban air)
