Di-(2-ethylhexyl) phthalate and its metabolites research trend: a bibliometric analysis
Summary
This bibliometric analysis mapped research trends on di-(2-ethylhexyl) phthalate (DEHP) and its metabolites, identifying growth areas, major contributors, and gaps in understanding human exposure, metabolism, and health effects of this common plasticizer.
Di-(2-ethylhexyl) phthalate (DEHP) is one of the most widely used plasticizers. Many studies focus on the impact of continuous exposure to DEHP on humans and ecosystems. In this study, the bibliometric analysis of DEHP and its metabolites research was conducted to assess the research performances, hotspot issues, and trends in this field. The data was retrieved from a Web of Science Core Collection online database. VOSviewer 1.6.18 was used to analyze. A total of 4672 publications were collected from 1975 to 2022 October 21. The number of publications and citations increased annually in the last decades. China had the largest number of publications, and the USA had the highest co-authorship score. The most productive and most frequently cited institutions were the Chinese Academy of Sciences and the Centers for Disease Control & Prevention (USA), respectively. The journal with the most publications was the Science of Total Environment, and the most cited one was the Environmental Health Perspectives. The most productive and cited author was Calafat A. M. (USA). The most cited reference was "Phthalates: toxicology and exposure." Four hotspot issues were as follows: influences of DEHP on the organisms and its possible mechanisms, assessment of DEHP exposure to the human and its metabolism, dynamics of DEHP in external environments, and indoor exposure of DEHP and health outcomes. The research trends were DNOP, preterm birth, gut microbiota, microplastics, lycopene, hypertension, and thyroid hormones. This study can provide researchers with new ideas and decision-makers with reference basis to formulate relevant policies.

Di-(2-ethylhexyl) phthalate and its Metabolites Research Trend: A Bibliometric Analysis
This bibliometric analysis maps 47 years of research into DEHP, a plasticizer widely used in PVC plastics, identifying its endocrine-disrupting and reproductive effects as major concerns and noting that microplastics are an emerging research trend in this field. DEHP is relevant to microplastic health risks because plastic particles can carry DEHP as a chemical contaminant, releasing it into the body upon ingestion or inhalation.
