Abstract

The present study involves the analysis of thirteen physiochemical parameters (pH, temperature, electrical conductivity, total dissolved solids, turbidity, alkalinity, hardness, calcium, magnesium, dissolved oxygen, biological oxygen demand, sulphate and nitrate) and five heavy metals (chromium, zinc, arsenic, lead and cadmium) from Chenab River and its tributaries (Neeru and Bichleri) at Ramban and Doda district, J&K. The analysis was done for two different seasons i.e. summer (June) and winter (December), 2022. The current investigation indicated that all the physiochemical parameters were in the permissible limit in both the seasons except few parameters (Ca, Mg, turbidity). In the analysis of heavy metals in both the seasons, it was found that there was no heavy metal contamination in all sampling sites except the Cr concentration which was found to be higher in all sites (except SXII) in summer season. The detailed analysis involved the calculation of various water quality indices which graded water quality under ‘good’ category as per WQI value whereas CPI and HPI value showed moderate to high pollution level in water during summer season. The study showed the seasonal variation in water quality parameters and thus encourage the need for regular monitoring of water quality to reduce pollution level.

利用各种指数评估切纳布河及其支流（查谟和克什米尔）水质的季节性变化

本研究分析了查谟和克什米尔兰班和多达地区切纳布河及其支流（尼鲁河和比奇勒里河）的 13 个理化参数（pH 值、温度、电导率、溶解性总固体、浊度、碱度、硬度、钙、镁、溶解氧、生物需氧量、硫酸盐和硝酸盐）和 5 种重金属（铬、锌、砷、铅和镉）。分析是在 2022 年的两个不同季节进行的，即夏季（6 月）和冬季（12 月）。目前的调查表明，除少数参数（钙、镁、浊度）外，两个季节的所有理化参数都在允许范围内。在对两个季节的重金属进行分析时发现，除夏季所有采样点（SXII 除外）的铬浓度较高外，所有采样点均未发现重金属污染。详细分析包括计算各种水质指数，根据 WQI 值，水质属于 "良好 "类别，而 CPI 和 HPI 值显示夏季水质处于中度到高度污染水平。研究表明，水质参数存在季节性变化，因此需要定期监测水质，以降低污染水平。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
