The presence of toxic metals such as vanadium in water resources has attracted considerable attention as a new concern in international health. Systematic review and meta-analysis were performed to assess the concentration of vanadium in water resources along with the relevant ecological risk assessment. Databases of Scopus, PubMed, and Embase were investigated to retrieve the related articles from January 01, 1974 to December 25, 2019. Twenty-eight articles containing 152 samples from 24 countries were included. Furthermore, the meta-analysis was conducted by the approach of z-score to estimate differences in the effect size. In addition, the mean of concentrations of vanadium was applied to calculate the risk assessment only to the water surface and choose the maximum environmental concentration (MEC) for demonstrate a worst-case scenario. Here, the risk assessment approach was used to show that the MEC of vanadium confirm the risk it for aquatic ecosystems, being fish (e.g., Danio rerio) our model organism due to their sensibility. According to findings, the MEC of vanadium in surface water varied from 0.010 μg L (USA) and 68 μg L (China), with an overall mean of 6.21 ± 13.3 μg L (mean ± standard deviation). The ecological risk assessment demonstrated that people living in some countries such as China and Japan were at an adverse ecological risk of vanadium in the water resources. Hence, essential control plans besides adequate removal techniques must be implemented for significant deracination of heavy metals like vanadium.
水资源中有毒金属（如钒）的存在已成为国际健康领域的一个新关注点。本研究进行了系统评价和荟萃分析，以评估水资源中钒的浓度及其相关的生态风险评估。研究人员调查了 Scopus、PubMed 和 Embase 数据库，以检索 1974 年 1 月 1 日至 2019 年 12 月 25 日期间的相关文章。共纳入 28 篇文章，包含 24 个国家的 152 个样本。此外，还采用 z 分数法进行荟萃分析，以估计效应量的差异。此外，还应用了钒浓度的平均值来计算风险评估，仅针对水面，并选择最大环境浓度（MEC）来展示最坏情况。这里，风险评估方法用于表明钒的 MEC 确认了其对水生生态系统的风险，鱼类（如斑马鱼）是我们的模式生物，因为它们具有敏感性。研究结果表明，地表水的钒 MEC 从 0.010μg/L（美国）到 68μg/L（中国）不等，总体平均值为 6.21±13.3μg/L（平均值±标准差）。生态风险评估表明，中国和日本等国的居民面临着水资源中钒的不利生态风险。因此，必须实施必要的控制计划，除了适当的去除技术外，还必须对像钒这样的重金属进行有效根除。
