Five stations were selected for this purpose , extending from A1 -٨١ rtream to A1- Sadeer District downstream . The percentage of؛ct uP؛str؛^ ؟ ٣, oligochaeta to total benthic invertebrates were calculated . The population density of evaluation. 'I'he results Were ٢٦؛ Tubificid worms without hair ehaetae was ©iso used IOBS(01igochaete Index of Sediment Bioindicati©n ), TUSP ٠ presented as indices Io (Tubificidae Species Percentage ) & degree of pollution Eo . IT was noticed that the 0 inام37.17 percentage of ©lig©chaeta to the total benthic invertebrates ranged between to 60.685 in station 3 , while the percentage ©f Tubificid w©rms t© ©ther ا stati©n oligochaeta ranged from 32% in station 2 to 74.17% in station 3.Io values ranged between 21.3 in station 3 to 22.3 in station I , while lobs index showed a higher value 7.62 in station 3 and lawer value 2.43 in station 3 .the higher value of TUSP index was 32,5 in stati©n 5 and the lawer valus was 15.9 in station 1 . Pollution degree F1( percentage ©f Tubificidae without hair M/gg& ل was rec©rded in stati©n 5-96 respectively ) and degree E in station 3,4&5 (percentage of Tubificidae & ة4-د without hair ehaetae was 15.95 , 15.95 & 16.16 respectively ). According to these results, stati©n 1 & 2 may be regarded as free fr©m p©lluti©n , while the other stations. were considered as slightly p©lluted

تم تقييم التلوث في نهر الديوانية بالاعتماد على اللافقريات القاعية حيث جمعت العينات منة خمس مناطق منتخبةعلى امتداد مجرى النهر} }
