Two species from common aquatic plants (Ceratophyllum demersum and Paspalum pespaioides) were used as bio-indicators of pollution with hydrocarbons compounds at Al-Kahlaa River in Missan province .Plant samples were collected during the period from October 2012 to November 2013. Concentrations of Total Petroleum Hydrocarbons (TPHs) in C. demersum ranged between 5 µg/g dry weight during winter and 58.97 µg/g dry weight during summer, whereas in P. pespaioides ranged between 3.18 µg/g dry weight during winter and 43.44 µg/g dry weight during summer. Also results of this study revealed a seasonal and spatial variations in concentrations of TPHs in both plants, the highest concentrations were recorded during summer whereas the lowest during winter. Results of statistical analysis revealed that there is no significant spatial variation whereas there is a significant seasonal variation in C. demersum. While results in P. pespaioides revealed that there was a significant spatial variation, whereas there is a significant seasonal variation. These plants are capable of accumulating TPHs and can be used as bio-indicators for monitoring pollution by this type of pollutants in aquatic environment.
