The growing concern over environmental pollution has spurred extensive research into various contaminants impacting ecosystems and human health. Emerging contaminants (ECs), including pharmaceuticals, personal care products, endocrine-disrupting chemicals, nanomaterials, and microplastics, have garnered significant attention due to their persistence, bioaccumulation, and toxicity. This study presents a comprehensive bibliometric analysis of EC research, aiming to detail the research landscape, highlight significant contributions, and identify influential researchers and pivotal studies. Data were sourced from the Web of Science, encompassing 62,670 documents from January 2000 to May 2024. Advanced bibliometric tools, including Bibliometrix, VOSviewer, and CiteSpace, were employed to analyze publication outputs, citation metrics, and collaboration patterns. The analysis revealed an exponential increase in EC research, with annual publications growing from fewer than 1,000 before 2006 to nearly 7,000 by 2022. Environmental Science & Technology emerged as the most influential journal. Based on the number of publications and citations as a country, China and the United States led in research outputs. Co-authorship and collaboration networks highlighted key hubs and prominent researchers, with significant contributions from environmental sciences, chemical engineering, and toxicology. Keyword co-occurrence analysis identified core themes, such as degradation, removal, and the impacts of ECs, reflecting evolving research interests and emerging topics. This bibliometric analysis provides valuable insights into the development and current state of EC research, serving as a resource for guiding future research efforts and fostering collaborations. The study indicates the critical need for continued research to address the challenges posed by ECs and develop effective regulatory policies and remediation strategies.
对环境污染日益增长的担忧促使人们对影响生态系统和人类健康的各种污染物展开广泛研究。新兴污染物（ECs），包括药物、个人护理产品、内分泌干扰化学物质、纳米材料和微塑料，因其持久性、生物累积性和毒性而备受关注。本研究对新兴污染物研究进行了全面的文献计量分析，旨在详细描述研究概况，突出重要贡献，并识别有影响力的研究人员和关键研究。数据来源于科学网，涵盖了2000年1月至2024年5月的62670篇文献。使用了包括Bibliometrix、VOSviewer和CiteSpace在内的先进文献计量工具来分析出版物产出、引用指标和合作模式。分析显示新兴污染物研究呈指数增长，年出版物数量从2006年前的不到1000篇增长到2022年的近7000篇。《环境科学与技术》成为最具影响力的期刊。以国家为单位，基于出版物数量和引用次数，中国和美国在研究产出方面领先。合著和合作网络突出了关键中心和杰出研究人员，环境科学、化学工程和毒理学做出了重大贡献。关键词共现分析确定了核心主题，如新兴污染物的降解、去除及其影响，反映了不断演变的研究兴趣和新出现的话题。这项文献计量分析为新兴污染物研究的发展和现状提供了有价值的见解，可作为指导未来研究工作和促进合作的资源。该研究表明迫切需要持续开展研究，以应对新兴污染物带来的挑战，并制定有效的监管政策和修复策略。
