Water Quality Assessment by Epiphytic Diatoms in Euphrates River between Haditha and Al-Baghdadi - Iraq

Abstract

The current study aims to study the environment and the presence of Epiphytic diatoms communities to the plants Ceratophllumdemersum and Phragmetsaustrales and the extent to which they are affected by the water environment of the Euphrates River from physical, chemical and biological factors, and to employ the quantitative and qualitative of epiphytic diatoms  to  the plants under current study in estimating the quality of the water of the Euphrates River. Fore biological indices and NSF-Water Quality Index were used hn this study for the  period from November 2019  to July 2020. The results revealed that the water quality of the Euphrates River were moderately to high   polluted ,  mesotrophic and high diversity epiphytic diatoms .
