Abstract

Background: The Iraqi environment, especially in the southern region, has been contaminated as a result of human activities. The detection of heavy metals in water samples is the preferred method for monitoring the toxic levels, which are very important for environmental protection and human health. Methods: Heavy metal concentrations of lead (Pb), cadmium (Cd), and nickel (Ni) were investigated in water samples from Al-Muthanna governorate, southern Iraq. The selected water samples were taken from different sources of tap water and river samples from the Euphrates and collected from various locations: residential, agricultural, and industrial. Results: The mean values of Pb, Cd, and Ni in tap water samples are 3.76, 2.62, and 84.88 μg/L, respectively, while the corresponding element levels in river water are 11.21, 7.58, and 104.31 μg/L, respectively. Rivers water samples recorded higher levels of toxic metals than tap water samples. Concentrations of toxic elements in water samples from industrial locations of Al-Muthanna governorate are higher than in the agricultural and residential places. Toxic metals in water samples can be arranged in the following sequence: Ni > Pb > Cd. Conclusion: The levels of heavy metals in most water samples were above the permissible levels according to USEPA; therefore, it is recommended that the water samples should be regularly monitored for heavy metals to prevent the effect of heavy metals contamination in the human food chain.

伊拉克穆萨纳省水样中铅、镉和镍的调查及污染指标评估

背景：伊拉克的环境，尤其是南部地区的环境，已经受到人类活动的污染。检测水样中的重金属是监测有毒物质含量的首选方法，这对环境保护和人类健康非常重要。方法：研究了伊拉克南部穆萨纳省水样中铅（Pb）、镉（Cd）和镍（Ni）的重金属浓度。所选水样取自不同来源的自来水和幼发拉底河的河水样本，采集地点包括居民区、农业区和工业区。研究结果自来水样本中铅、镉和镍的平均值分别为 3.76、2.62 和 84.88 微克/升，而河水中相应元素的含量分别为 11.21、7.58 和 104.31 微克/升。河水样本的有毒金属含量高于自来水样本。穆萨纳省工业区水样中有毒元素的浓度高于农业区和居民区。水样中的有毒金属可按以下顺序排列：镍（Ni）；铅（Pb）；镉（Cd）。结论大多数水样中的重金属含量都超过了美国环保局规定的允许水平；因此，建议定期对水样进行重金属监测，以防止重金属污染对人类食物链造成影响。

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.
