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.

伊拉克卡拉尔市废水排放对Diyala-Sirwan河水质的影响:污染评估,重金属污染的健康风险

在这项工作中,已进行了一项综合评估,以了解从卡拉尔市排出的废水对伊拉克Diyala-Sirwan河水质参数的影响。Ca,K,Na,Mg,pH,电导率,溶解氧,总溶解固体,浊度,生物需氧量和总硬度以及Fe,Mn,Ni,Cu,Zn,Hg的重金属的理化参数水平铝,钡,硒和砷的含量已通过电感耦合等离子体发射光谱法和其他装置确定。污染指数,健康风险评估和多因素分析已被用于评估在影响点之前和之后不同地点废水排放对河水水质的污染强度。在废水排放点之后的所有采样地点,都使用不同的河水指数来确定轻度到中度的污染水平。聚类分析和相关分析表明,废水排放对河水水质的影响正在研究区内沿河发生。对河流中重金属的非致癌性健康风险评估,表明存在潜在风险,可能对人们的健康造成危害,尤其是在出水点之后。此外,在同一地区还认识到砷和汞的重金属对致癌风险的显着影响。因此,这项研究有助于清楚地了解由于从卡拉尔市排放未经处理的废水而导致的迪亚拉-西尔万河水质发生的变化。聚类分析和相关分析表明,废水排放对河水水质的影响正在研究区内沿河发生。对河流中重金属的非致癌性健康风险评估,表明存在潜在风险,可能对人们的健康造成危害,尤其是在出水点之后。此外,在同一地区还认识到砷和汞的重金属对致癌风险的显着影响。因此,这项研究有助于清楚地了解由于从卡拉尔市排放未经处理的废水而导致的迪亚拉-西尔万河水质发生的变化。聚类分析和相关分析表明,废水排放对河水水质的影响正在研究区内沿河发生。对河流中重金属的非致癌性健康风险评估,表明存在潜在风险,可能对人们的健康造成危害,尤其是在出水点之后。此外,在同一地区还认识到砷和汞的重金属对致癌风险的显着影响。因此,本研究有助于清楚地了解由于从卡拉尔市排放未经处理的废水而导致的迪亚拉-西尔万河水质发生的变化。表明存在潜在的风险,可能危害人们的健康,尤其是出院后。此外,在同一地区还认识到砷和汞的重金属对致癌风险的显着影响。因此,这项研究有助于清楚地了解由于从卡拉尔市排放未经处理的废水而导致的迪亚拉-西尔万河水质发生的变化。表明存在潜在的风险,可能危害人们的健康,尤其是出院后。此外,在同一地区还认识到砷和汞的重金属对致癌风险的显着影响。因此,这项研究有助于清楚地了解由于从卡拉尔市排放未经处理的废水而导致的迪亚拉-西尔万河水质发生的变化。
