Chronic low-concentration benzene exposure and hematotoxicity research trends from 1992 to 2022

Abstract

Abstract Background The purpose of this study was to analyze nearly three decades of academic research on chronic low-level benzene exposure and hematotoxicity with qualitative and quantitative analysis. Methods Publications from 1992 to 2022 were extracted from the Science Citation Index Expanded (SCI-E) and the Social Sciences Citation Index (SSCI) of the Web of Science Core Collection (WoSCC) of Thomson Reuters. WoSCC, Microsoft Excel 2016, and Citespace were used to analyze the publication outcomes, journals, countries, institutions, authors, and research areas. Results As of July 13, 2022, there have been 521 papers published on chronic low-level benzene exposure and hematotoxicity. Environmental Health Perspectives has published the most articles, the United States is the leading country, Fudan University is the leading institution, Chen Y has published the most articles, Snyder R has co-cited the most articles, and Toxicology is ranked #1 in the research field. Conclusion Many high-quality articles have been published in the last three decades. Fudan University and the Chinese Center for Disease Control and Prevention are in the first echelon of research on long-term low-level benzene exposure and hematological toxicity. Chen Y, Ashley D, and Bertazzi P may be good candidates for collaboration in this research area. In the meantime, occupational disease researchers should pay close attention to the studies of hematological and carcinogenicity caused by occupational benzene exposure.
