摘要

目前的研究旨在评估六种重金属对人类的风险,即锌、铁、铜、镉、砷和铅,这些重金属存在于班加罗尔农村地区Kudlu村的水罐水中。从2021年9月到2023年2月,对水样进行了为期18个月的分析。对收集的水样进行了理化和微生物参数评估,其中包括04罐水和01纯净水。考虑了氯、pH、碱度、三聚氰尿酸、总硬度、电导率、温度、钠、钾、总溶解固体、钙和镁。此外,还检测了大肠杆菌的进一步细菌学污染。根据这些参数计算水质指数。水车水样水质指标显示水质不适宜饮用。计算了成人和婴儿对这些重金属的暴露频率、危害系数、致癌和非致癌风险等指标。结果表明,在研究时间段内观察到的重金属浓度对人体健康不构成风险。

Human health risk assessment of selected heavy metals in tanker water: A study from Kudlu, Bengaluru

Human health risk assessment of selected heavy metals in tanker water: A study from Kudlu, Bengaluru

The current study aims to assess the risk in humans due to six heavy metals, namely zinc, iron, copper, cadmium, arsenic, and lead, present in the tanker water supplied in the rural area of Bangalore called Kudlu village. Water samples were analyzed for a total period of 18 months between September 2021 to February 2023. Physicochemical and microbiological parameters were assessed for the collected water samples that included 04 tanker water and 01 purified water. Chlorine, pH, alkalinity, cyanuric acid, total hardness, conductivity, temperature, sodium, potassium, total dissolved solids, calcium, and magnesium was taken into consideration. Further bacteriological contamination by E.coli was also tested. Water Quality Indices were calculated based on these parameters. Water quality indices of the tanker water samples indicated that the quality of water was not suitable for drinking. The indices like exposure frequency, Hazard coefficient, carcinogenic and non-carcinogenic risks were calculated for both adults and infants for these heavy metals. The results indicated that the heavy metal concentration observed during the studied time period poses no risk to human health.

期刊介绍: Chinese Journal of Analytical Chemistry(CJAC) is an academic journal of analytical chemistry established in 1972 and sponsored by the Chinese Chemical Society and Changchun Institute of Applied Chemistry, Chinese Academy of Sciences. Its objectives are to report the original scientific research achievements and review the recent development of analytical chemistry in all areas. The journal sets up 5 columns including Research Papers, Research Notes, Experimental Technique and Instrument, Review and Progress and Summary Accounts. The journal published monthly in Chinese language. A detailed abstract, keywords and the titles of figures and tables are provided in English, except column of Summary Accounts. Prof. Wang Erkang, an outstanding analytical chemist, academician of Chinese Academy of Sciences & Third World Academy of Sciences, holds the post of the Editor-in-chief.
