Cadmium pollution turns out to be a global environmental problem. This study conducted a quantitative and qualitative bibliometric analysis based on 9188 research items from the Web of Science Core Collection published in the last 20 years (2000-2020), presenting an in-depth statistical investigation of global freshwater cadmium research progress and developing trend. Our results demonstrated that the researchers from China, the USA, and India contribute the most to this field. The primary sources of cadmium are mining, industry, wastewater, sedimentation, and agricultural activities. In developing countries, cadmium exposure occurs mainly through the air, freshwater, and food. Fish and vegetables are the main food sources of cadmium for humans because of their high accumulation capability. Source evaluation, detection, and remediation represent the main technologies used to clean up cadmium-contaminated sites. To mitigate the risk of cadmium contamination in freshwater, biomarker-based cadmium monitoring methods and integrated policies/strategies to reduce cadmium exposure merit further concern.
镉污染已成为一个全球性的环境问题。本研究基于过去20年（2000 - 2020年）发表在科学网核心合集中的9188篇研究论文进行了定量和定性的文献计量分析，对全球淡水镉研究进展和发展趋势进行了深入的统计调查。我们的结果表明，来自中国、美国和印度的研究人员在该领域贡献最大。镉的主要来源是采矿、工业、废水、沉积和农业活动。在发展中国家，镉暴露主要通过空气、淡水和食物发生。由于鱼类和蔬菜具有较高的镉积累能力，它们是人类镉的主要食物来源。源评估、检测和修复是用于清理镉污染场地的主要技术。为降低淡水中镉污染的风险，基于生物标志物的镉监测方法以及减少镉暴露的综合政策/策略值得进一步关注。
