In Antarctica, human activities have been reported to be the major cause of the accumulation of heavy metal contaminants. A comprehensive bibliometric analysis of publications on heavy metal contamination in Antarctica from year 2000 to 2020 was performed to obtain an overview of the current landscape in this line of research. A total of 106 documents were obtained from Scopus, the largest citation database. Extracted data were analysed, and VOSviewer software was used to visualise trends. The result showed an increase in publications and citations in the past 20 years indicating the rising interest on heavy metal contamination in the Antarctic region. Based on the analysis of keywords, the publications largely discuss various types of heavy metals found in the Antarctic water and sediment. The analysis on subject areas detects multiple disciplines involved, wherein the environmental science was well-represented. The top countries and authors producing the most publication in this field were from Australia, China, Brazil and Chile. Numerous efforts have been exercised to investigate heavy metal pollution and its mitigation approaches in the region in the past decades. This paper not only is relevant for scholars to understand the development status and trends in this field but also offers clear insights on the future direction of Antarctic heavy metal contamination and remediation research.
在南极洲，人类活动已被报告是重金属污染物积累的主要原因。本研究对 2000 年至 2020 年期间发表的关于南极洲重金属污染的出版物进行了全面的文献计量分析，以了解该研究领域的现状。从最大的引文数据库 Scopus 中获取了 106 份文件。提取的数据进行了分析，并使用 VOSviewer 软件对趋势进行了可视化。结果表明，过去 20 年来出版物和引文数量的增加表明，人们对南极地区重金属污染的兴趣日益浓厚。根据关键词分析，这些出版物主要讨论了在南极水域和沉积物中发现的各种类型的重金属。对主题领域的分析发现，涉及多个学科，其中环境科学的代表性最强。在该领域发表最多出版物的国家和作者主要来自澳大利亚、中国、巴西和智利。过去几十年，人们为研究该地区的重金属污染及其缓解方法做出了许多努力。本文不仅对学者了解该领域的发展现状和趋势具有重要意义，而且为南极地区重金属污染和修复研究的未来方向提供了清晰的见解。
