Abstract

Rivers are one of the most crucial fluid ecosystems, primarily due to their freshwater content. Understanding the trends in water quality changes in seas enables the anticipation of future challenges and the implementation of plans to address them. Water quality management necessitates the collection and analysis of a vast amount of data and water quality parameters. To facilitate this, various tools have been developed for simpler assessment of data and water quality, among which water quality indices are highly utilized. The objective of this study is to assess the water quality of the Balkh Sea using the (IRWQISC) and (IRWQIST) indices, alongside examining the levels of heavy metals, cations, anions, and its physical characteristics. Sampling was conducted at two time points: initially in October 2022, with heavy metal analysis performed using Flame Atomic Absorption Spectroscopy (FAAS), and subsequently in April 2023, where samples were collected from various points, and the concentrations of cations, anions, pH, and electrical conductivity (EC) were measured. Data analysis was carried out using SPSS version 26, and ArcGIS 10.4.1 was employed for map production. The research findings indicate a trend of heavy metal changes as follows: Al>As>Pb>Cd>(Cr=Co=Ni)>Hg. Based on the calculation of the toxicity index (IRWQIST), the studied water falls into the poor category. Consequently, sea water, due to the presence of heavy metals such as lead, cadmium, arsenic, and mercury, is relatively to very toxic and unsuitable for drinking. Additionally, it may cause detrimental effects for other uses such as agriculture and livestock farming.
古里水泥厂的粉尘和废水造成巴格兰河水污染的调查:案例研究
河流是最重要的流体生态系统之一,这主要是因为其含有淡水。了解海洋水质变化的趋势有助于预测未来的挑战并实施应对计划。水质管理需要收集和分析大量数据和水质参数。为此,开发了各种工具来简化数据和水质评估,其中水质指数得到了广泛应用。本研究的目的是使用(IRWQISC)和(IRWQIST)指数评估巴尔赫海的水质,同时检测重金属、阳离子、阴离子的含量及其物理特征。采样在两个时间点进行:最初在 2022 年 10 月,使用火焰原子吸收光谱(FAAS)进行重金属分析;随后在 2023 年 4 月,从不同地点采集样本,测量阳离子、阴离子、pH 值和电导率(EC)的浓度。数据分析采用 SPSS 26 版,地图绘制采用 ArcGIS 10.4.1。研究结果表明,重金属的变化趋势如下:Al>As>Pb>Cd>(Cr=Co=Ni)>Hg。根据毒性指数(IRWQIST)的计算结果,所研究的海水属于劣质水。因此,由于铅、镉、砷和汞等重金属的存在,海水的毒性相对较大,不适合饮用。此外,它还可能对农业和畜牧业等其他用途造成不利影响。
