A bibliometric analysis was performed to assess historical and recent research trends regarding e-waste studies from 1998 to 2018. Documents related to e-waste were identified from the Clarivate Analytics Web of Science© (WoS) database, and a total of 3311 academic articles was retrieved. The analysis was performed from four main aspects: (1) publication activity by year, by WoS category, and by geographic distribution; (2) journals; (3) most-cited papers; and (4) top 10 countries and author keyword analysis. The number of publications concerning e-waste issues has increased substantially over the last 20 years, especially in the environmental science category, and more than a third of the publications were produced in China (1181 records). Waste Management and Environmental Science & Technology were the most sought-after journals for disseminating the results. Studies related to "e-waste flow analysis," "recycling," "recovery of precious metals," and "risk assessment of recycling areas" have been the most common for several years. The analysis of keywords suggested that there are many topics on electronic waste and that each country has presented a different focus of research. Overall, the bibliometric analysis proved to be an efficient tool with which to monitor historical and current research trends and to evaluate the sheer volume of currently existing scientific literature on e-waste topics.
进行了文献计量分析，以评估 1998 年至 2018 年期间有关电子废物研究的历史和近期研究趋势。从科睿唯安 Web of Science©（WoS）数据库中确定了与电子废物相关的文献，共检索到 3311 篇学术文章。分析从四个主要方面进行：（1）按年份、WoS 类别和地理分布的出版活动；（2）期刊；（3）被引频次最高的论文；（4）前 10 个国家和作者关键词分析。过去 20 年来，有关电子废物问题的出版物数量大幅增加，特别是在环境科学类别中，超过三分之一的出版物来自中国（1181 篇记录）。《废物管理》和《环境科学与技术》是传播研究成果最受欢迎的期刊。多年来，与“电子废物物流分析”、“回收”、“贵金属回收”和“回收地区风险评估”相关的研究一直很常见。关键词分析表明，电子废物方面有很多主题，每个国家都提出了不同的研究重点。总的来说，文献计量分析被证明是一种有效的工具，可以监测历史和当前的研究趋势，并评估目前有关电子废物主题的大量科学文献。
