Water `assessment and algal composition study was conducted near Koysenjaq district for nine sites including (4) springs and (5) streams. Monthly water samples collected from April-2013 to March-2014 and 15 physico-chemicals parameters and algal content were analyzed. Generally, pH of water tend to be in alkaline side of neutrality. Mean values of electrical conductivity ranged between 272-441µs.cm-1 in January and July respectively. Total hardness extended from hard to very hard water. Cation arranged in order as follows: Ca> Mg>Na>K. Higher mean value of ammonium recorded in site 6 was 14.8 µg N.NH 3 .l-1 , and minimum value of nitrite was 0.68µg N.NO 2 .l-1 in site 6. Mean values of phosphate ranged between (0.82-4.5µg P-PO 4 .l-1). Highest value of dissolved oxygen were observed in sites 7, 8 and 9, while the minimum value of biochemical oxygen demand recorded in site 2 was 0.7mg.l-1. A total 73 species of algal species were identified of which belong to Bacillariophyceae (25 species), Cyanophyceae (23 species), Chlorophyceae (16 species), Euglenophyceae (4 species), Charophyceae and Xanthophyceae (2 species for each one) and 1 species belong to Rhodophyceae. Multivariate statistical techniques results revealed that water quality of the monitored water bodies were influenced by many pollution sources including the geological formation of the area, agricultural activities and effluent of domestic sewage water.

“…Usually, surface water quality is evaluated depending upon various physical, chemical, and biological parameters (Issa 2017). Since a great number of industrial effluents and sewage are likely to have been discharged into surface water sources, heavy metals are taken into consideration for effective quality evaluation of any surface water body (Kaushik et al 2009;Mu et al 2015;Ullah et al 2019). Levels of heavy metals and other chemical quality parameters in surface waters are continuously changing due to various inputs, involving natural and anthropogenic sources (Ali et al 2016;Muhammad and Ahmad 2020).…”

In this work, a comprehensive assessment has been performed to understand impact of wastewater discharge from Kalar city on water quality parameters of Diyala-Sirwan river, Iraq. Levels of physicochemical parameters of Ca, K, Na, Mg, pH, electrical conductivity, dissolved oxygen, total dissolved solid, turbidity, biological oxygen demand, and total hardness, and heavy metals of Fe, Mn, Ni, Cu, Zn, Hg, Al, Ba, Se, and As have been determined by inductively coupled plasma optical emission spectroscopy and other devices. Pollution indices, health risk assessment, and multivariate analysis have been applied to evaluate pollution intensity originated from wastewater discharge on river water quality at different locations, before and after the impact point. Pollution levels of slight to moderate have been identified using different indices for the river water at all sampling locations after the wastewater discharge point. Cluster and correlation analyses showed that the impact of wastewater discharge on the river water quality was occurring along the river within the study area. Non-carcinogenic health risk assessment for heavy metals in the river, indicating a potential risk, might on people's health, especially after discharge point. Furthermore, a significant effect of carcinogenic risk by heavy metals of As and Hg was recognized in the same area. This study thus helps to understand clearly the alteration that happened in the water quality of Diyala-Sirwan river due to the discharge of untreated wastewater from Kalar city.

“…Therefore, numerous studies illustrated the water chemical parameters (e.g., nutrients, heavy metals, etc.) in the rivers of the LTB (Bian et al, 2016;Huang et al, 2017;Mu et al, 2015). By contrast, phytoplankton in these rivers have received less attention compared with Lake Taihu which suffers serious algal blooms (Deng et al, 2011;Du et al, 2014;Wu et al, 2016).…”

We investigated the characteristic of phytoplankton community structure across the entire Lake Taihu Basin (LTB), one of the most developed areas in China. A morphologically based functional group (MBFG) proposed by Kruk et al. (2010), especially potential toxic cyanobacteria (group III and VII), was also illustrated. Samples were collected at 96 sites along main rivers throughout the four seasons from September 2014 to January 2016. Significant differences in the phytoplankton community structure were observed at spatial (particularly between Huangpu/Tiaoxi and the other 4 river systems) and seasonal scales. On a spatial basis, high variability was observed in the mean phytoplankton biomass, with a relatively high value of 3.13 mg L−1 in Yanjiang system and a relatively low value in Huangpu (1.23 mg L−1) and Tiaoxi (1.44 mg L−1) systems. The mean biomass of potential toxic cyanobacteria accounted for 18.28% of the mean total biomass spatially, which was more abundant in Nanhe and Yanjiang systems. Spatial autocorrelation was weak for the total biomass and its four main components (bacillariophyta, chlorophyta, euglenophyta, and cyanobacteria) at whole basin scale regardless of season. Regarding the river system, significant autocorrelation was scarcely observed in all the river systems except Huangpu, especially in the inflows. The characteristic in terms of hydrological and environmental conditions may determine the community structure of the 6 river systems. Our study highlighted the importance of monitoring based on a large spatial scale, and more attention should be paid to potential toxic cyanobacteria for water quality management purposes.
