Water quality, diatoms, pollution and Shannon diversity indices for the Euphrates river

Abstract

Al-Tamimi AAM., Braak MM., Water quality, diatom, pollution and Shannon diversity indices from the Euphrates river, Onl J Vet Res., 23 (2):161-, 2019. Authors report biological and water quality indices from the Euphrates river between Ramadi and Fallujah in Western Iraq from November 2017 to July 2018. We assessed water quality index (NSF-WQI), Trophic Diatoms (TDI), Pollution Tolerance (PTI) and Shannon Diversity Indexes (H). Most of the biological indices reflected water quality low to moderately polluted, oligotrophic to mesotrophic, with moderate biodiversity by diatoms and medium to good water quality. The water quality index (NSF-WQI) showed some consistency with the values of some physical and chemical parameters. The comparison between the biological indices and the water quality index showed no clear pattern between the water quality index and the PTI, but some showed compatibility between H, PTI and NSF-WQI
