The emerging toxicants, N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine quinone (6PPD-Q), resulting from environmental exposure to N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD), have gained considerable attention owing to their ubiquitous occurrence and high toxicity. We performed a scientometric analysis on this topical area of research over the past two decades, spanning from 2004 to April 2024. The overarching aim was to reveal potential future directions in this research area, exploring several key aspects. These included publication and citation growth trends, relevant subject fields, distribution of contribution by country, influential journals in the field, keyword co-occurrence network and cluster analysis, and identification of top authors. The information was collected from the Scopus database and processed using the VOS viewer software. We observed a notable increase in the number of publications over the past four years. With a share of 46.2% of publications, "Environmental Sciences" dominated as the primary scientific category. Among all journals, "Science of the Total Environment" was the most prolific, publishing 33 documents, accounting for 15.6% of the total records. China, representing 76 publications (36%), followed by the United States, with 40 (18.9%), stood out as the leading countries. The occurrence of keywords such as "Pollution exposure", "Mass spectrometry", and "toxicity" highlighted the importance of assessing the toxicological properties, analytical methods, and environmental implications of these emerging contaminants to mitigate their adverse effects and protect environmental and human health. Cai, Zongwei from Hong Kong Baptist University was highly productive in this field, publishing 11 papers. Based on the bibliometric analysis presented, it seems that the future direction of research on 6PPD and 6PPD-Q will shift towards strategies focused on their removal and treatment.
新兴的有毒物质 N-(1,3-二甲基丁基)-N'-苯基-p-苯二胺醌（6PPD-Q）是由于环境暴露于 N-(1,3-二甲基丁基)-N'-苯基-p-苯二胺（6PPD）而产生的，由于其普遍存在和高毒性，引起了相当大的关注。我们对过去二十年来这一研究领域进行了科学计量分析，时间跨度为 2004 年至 2024 年 4 月。总体目标是揭示该研究领域的潜在未来方向，探讨几个关键方面。这些方面包括出版物和引文的增长趋势、相关学科领域、国家贡献的分布、该领域有影响力的期刊、关键词共现网络和聚类分析以及顶级作者的识别。这些信息是从 Scopus 数据库中收集的，并使用 VOS viewer 软件进行处理。我们观察到过去四年出版物数量显著增加。在过去的四年中，“环境科学”以 46.2%的出版物份额占据主导地位，是主要的科学类别。在所有期刊中，“环境科学与技术”发表的文章最多，发表了 33 篇文章，占总记录的 15.6%。中国以 76 篇（36%）的发表量位居榜首，其次是美国，发表了 40 篇（18.9%）。“污染暴露”、“质谱”和“毒性”等关键词的出现，突出了评估这些新兴污染物的毒理学性质、分析方法和环境影响的重要性，以减轻其不利影响，保护环境和人类健康。来自香港浸会大学的蔡宗威（Zongwei Cai）在该领域的研究成果丰硕，发表了 11 篇论文。根据呈现的文献计量分析，6PPD 和 6PPD-Q 的未来研究方向似乎将转向关注它们的去除和处理策略。
