“…According to the Hynes classification [22], the river water in all sites classified as doubtful to bad. Statistical analysis results indicate that there were significant differences between the sites and months (p≤ 0.05), these results disagreed with [23] on Euphrates River that recorded values ranged between (4.87-47.5) mg/l. The main causes of this different is the nature of water body, Sawa lake is closed system compare with Euphrates River and it exposed to fewer external pollutants due to little or no water flow.…”

One of the primary issues that harms both man and his environment is water pollution. This study was carried out to assess the level of organic pollutants in Sawa lake water. Water Sampling collected from October 2021 to February 2022, monthly, samples taken from three different sites. Biological oxygen demand (BOD5) measured by the BOD Sensor after calibration and processing, and some related environmental parameters were also measured. The results showed that BOD5 values ranged between (5.9-7.6) mg/l, higher value was 12.5 mg/l recorded in S1 and S2 during February, and lower concentration (3 mg/l) recorded in S2 during November. The value of BOD5 in all periods of study was 6.67 mg/l. The findings of the statistical analysis showed that there were significant differences between the sites and months (p≤ 0.05). Monthly changes in the physicochemical properties of lake water and the autochthonous organic matter may be a reason for increasing the concentration of organic content, in addition to the wastes that arrives from near area. According to the Hynes classification, the river water in all sites classified as doubtful to bad. Negative significant correlations were founds between BOD5 and DO (r= -0.75) and positive significant correlations between BOD5, EC and nitrate (r= 0.54, r=0.42), respectively.

“…Th e Euphrates River is passing through eight provinces from the west, centre, and south of Iraq, the river water are fresh with a steady increase in salinity to the south. Some studies on Euphrates river or its branches, which focused on studying Mollusca including (Al-Fanharawi and Ibrahim, 2014;Salman and Nassar, 2014;Ghulam, 2019).…”

The current study was conducted in one of the most important water sources in Iraq, the Euphrates river to evaluate the diversity and density of Gastropoda and Bivalvia by using appropriate biodiversity indices. The samples were taken monthly from the river sediments, during the period from 1 July 2018 to 1 June 2019 from 3 stations, the distance between the first and second stations is 5 km and the second and third station is 7 km. The results showed the presence of 9 species, 7 of them belong to the Gastropoda and 2 belong to the Bivalvia. The total number of Mollusca was 2675 ind/m2. The species Melanoides tuberculata (Muller 1774) showed more relative abundance in the Euphrates River during the study period. The highest value for richness was recorded in March at station 3, while the Shannon Wiener diversity index, the results showed that the highest values were in April and May for all sites, and the highest value for eveness was recorded in January at Station 3, while the highest value for dominance was during October at station 3. Moreover, the current study included the monthly measurement of five environmental factors: water temperature, pH, salinity, dissolved oxygen, and organic matter.
