Abstract

This study investigated the scientific landscape of research on phthalate esters biodegradation using the Web of Science database up to 2022. The collected data were analysed using bibliometric and scientometric tools. A total of 863 scholarly documents published between 1975 and 2022 in 266 journals were selected for analysis. The analysis revealed a growth rate of 6.9% in the research field, with an average document age of 10.8 years. The trend in phthalate biodegradation research showed a steady increase in citations until 1997, followed by a slight decrease until 2005, but experienced renewed interest in 2006 and significant growth in 2016. Chemosphere was identified as the prominent journal, and China had the most publications (417) followed by India (78), while Africa had the least productivity, with South Africa contributing the highest number of publications (9). Thematic evolution in the field focused on understanding the mechanisms of phthalate breakdown through microbial enzymes like hydrolases, while revealing changing patterns with the current research focus being "microbial community" and "metabolism" as indicated by strongest burstiness strengths. The study sheds light on the scientific landscape of phthalate biodegradation research, highlighting research gaps and suggesting potential research policy improvements such as enhancing funding and capacity building in biodegradation research in Africa.
邻苯二甲酸酯生物降解研究的科学景观:文献计量学和科学计量学研究
本研究使用Web of Science数据库调查了邻苯二甲酸酯生物降解研究的科学景观,直至2022年。使用文献计量学和科学计量学工具对收集到的数据进行分析。从1975年到2022年,在266个期刊上发表的863篇学术论文被选为分析对象。分析显示,研究领域的增长率为6.9%,平均文献年龄为10.8年。邻苯二甲酸酯生物降解研究的趋势显示,在1997年之前,引用量稳步增长,随后在2005年之前略有下降,但在2006年重新受到关注,并在2016年显著增长。Chemosphere被确定为杰出的期刊,中国的出版物最多(417篇),其次是印度(78篇),而非洲的生产力最低,南非的出版物数量最多(9篇)。该领域的专题发展集中在理解通过水解酶等微生物酶分解邻苯二甲酸酯的机制。同时揭示变化规律,目前的研究重点是“微生物群落”和“代谢”,由最强的爆发强度表示。这项研究揭示了邻苯二甲酸酯生物降解研究的科学前景,突出了研究差距,并提出了潜在的研究政策改进,例如加强非洲生物降解研究的资助和能力建设。
