Pollution of the aquatic ecosystem due to different trace elements has become a global concern which has raised health-related issues for both aquatic and human life. Industrial and agricultural water run-off drained into the rivers and deposit trace elements in water, sediments and planktons. This study was designed to calculate the burden of trace elements such as aluminium (Al), arsenic (As), barium (Ba), and lead (Pb) in the river water of Punjnad Headworks, Bahawalpur, Punjab, Pakistan. Samples were collected from surface water, bed sediments and planktons during autumn, winter and spring seasons (September 2018 to May 2019). The results showed that the concentration of Pb was highest in surface water (453.87 mg L), while that of Al was highest in sediments (370.24 µg g) and plankton (315.05 µg g). A significant difference was found in metal concentrations among surface water, bed sediments and plankton at different sampling stations during various seasons. Importantly, the Exp (0.71, 1.23, 0.34, 0.02 for Pb, As, Al, and Ba, respectively) and Exp (7.09, 1.23, 3.42, and 2.48 for Pb, As, Al, and Ba, respectively) for trace elements were below 1.0 suggesting non-significant adverse effects of trace elements on human health. This study provided better understanding of various pollutants and their concentrations in water sources at the studied location.
由于不同微量元素造成的水生态系统污染已成为全球关注的问题，这给水生生物和人类的健康带来了相关问题。工业和农业用水排入河流，在水中、沉积物和浮游生物中沉积微量元素。本研究旨在计算巴基斯坦旁遮普省巴哈瓦尔布尔 Punjnad 拦河坝河流水体中铝（Al）、砷（As）、钡（Ba）和铅（Pb）等微量元素的负担。在秋季、冬季和春季（2018 年 9 月至 2019 年 5 月）期间，从地表水、底泥和浮游生物中采集样本。结果表明，铅在地表水中的浓度最高（453.87mg/L），而铝在沉积物（370.24µg/g）和浮游生物（315.05µg/g）中的浓度最高。在不同季节的不同采样点，地表水、底泥和浮游生物中的金属浓度存在显著差异。重要的是，微量元素的 Exp（0.71、1.23、0.34、0.02 分别为 Pb、As、Al 和 Ba）和 Exp（7.09、1.23、3.42 和 2.48 分别为 Pb、As、Al 和 Ba）低于 1.0，表明微量元素对人类健康没有显著的不良影响。本研究提供了对研究地点水源中各种污染物及其浓度的更好理解。
