The occurrence, distribution, and fate of persistent organic pollutants (POPs) have been extensively studied worldwide; however, the patterns and dynamics of scientific publications on POPs are still unclear. In this study, the research trends on dirty dozen POPs, which are identified under the Stockholm Convention (SC) for immediate action were investigated and evaluated in a broad context to obtain up-to-date information. For this purpose, bibliometric analysis was carried out between 1945 and 2021 using the Web of Science (WoS) database. A total of 197,029 publications were analyzed. "Environmental Sciences" was the most popular research category and the USA was the leading country in dirty dozen POPs studies. The research hotspots are related to the most used keywords such as "Polychlorinated Biphenyls", "Dioxin" and "Persistent Organic Pollutants". In the evaluation of keyword clusters with highlighted research points, 7 clusters were obtained from the publications, which are related to the chemical properties, synthesis, structures, health effects, and analysis methods of dirty dozen POPs. The number of publications and, accordingly, the scientific interest in dirty dozen POPs listed under the SC has not reached equilibrium and continues regardless of the level of development of countries in the world.
持久性有机污染物（POPs）的发生、分布和命运已在全球范围内得到广泛研究；然而，持久性有机污染物科学出版物的模式和动态仍不清楚。在本研究中，在斯德哥尔摩公约（SC）立即采取行动下确定的“肮脏十二”POPs 的研究趋势在广泛的背景下进行了调查和评估，以获取最新信息。为此，使用 Web of Science（WoS）数据库进行了 1945 年至 2021 年的文献计量分析。共分析了 197029 篇出版物。“环境科学”是最受欢迎的研究类别，美国在“肮脏十二”POPs 研究方面处于领先地位。研究热点与最常用的关键词有关，如“多氯联苯”、“二恶英”和“持久性有机污染物”。在对突出研究点的关键词聚类进行评估时，从出版物中获得了 7 个聚类，这些聚类与“肮脏十二”POPs 的化学性质、合成、结构、健康影响和分析方法有关。列入斯德哥尔摩公约的“肮脏十二”POPs 的出版物数量以及因此产生的科学兴趣尚未达到平衡，并在世界各国的发展水平下持续不断。
