Water samples analysis In the laboratory, all returned water samples for heavy metals analysis and other chemical elements were acidified by adding concentrated nitric acid HNO 3 and stored at 25 0C. Otherwise, the elevated PI of Hg and Ca after impact point suggests a release of some industrial effluents into the city wastewater of these two parameters Hammes et al. Water Pollution index PI and overall index of pollution OIP Pollution index PI evaluates water pollution by metals that originated from different origins.
Kalar city of about 281 K population Kurdistan Region Statistics Officeand comprising many commercial and industrials activities with agricultural in suburban areas as well, which lastly are discharged into Diyala-Sirwan river without treatment. Before the impact point, PI values range between 0. Many former studies have been performed on river pollution caused by city wastewater Evaluation of health risks associated with wastewater treatment and sludge composting.

Also, strong relationships between heavy metals in the river after the impact point suggest similar input sources and transport ways of these metals Jiang et al. Water sample collection and preparation In the study area, water samples were collected from sampling locations from four locations along Diyala-Sirwan river in January 2019: L1 before impact point of Kalar city wastewater discharge, by 10 km; L2 directly at the impact point of wastewater discharge; L3 after 5 km from impact point; and L4 at 10 km from the impact point.

Water samples pollution assessment Heavy metal pollution index HPI HPI as proposed by Mohan et al. For non-carcinogen risk, the risk on human life and health was assessed by applying hazard quotients HQ for heavy metals and hazard index HI Tripathee et al.
Pollution evaluation indices of Diyala-Sirwan River Calculations of pollution evaluation indices HPI, HEI, C d, PI, and OIP in this study were based on river water quality standards taken from the literature as illustrated in Table. ; Ibrahim ; Kamil and Adel Abdulrazzaqas a result of industrial and rural wastewater discharges. River contamination with heavy metals is increasingly becoming an important issue, because of toxic, non-biodegradable behavior of heavy metals in aquatic biological systems Jadoon et al.
The results obtained in this study are important to build a reliable system for environmental monitoring and measuring pollution of Diyala-Sirwan river.
Water samples collected from the location L2 reveal a significant deterioration in water quality, all physicochemical parameters, and heavy metals were at elevated levels, close to or higher than MAL, showing the harmful effect of wastewater discharging without treatment into the river water body. Bangladesh, using multivar analy pollut evaluat indice Environ Monit Assess 187:4075. 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.
