Analysis of International Research Hotspots in Forensic Toxicology Based on Bibliometrics

doi:10.3969/j.issn.1671-2072.2025.02.003

Abstract

Abstract: A bibliometric analysis of the overall development trend in the international forensic toxicology field over the last decade was performed, investigating authors, institutions, and countries with high academic productivity and influence, and mapping the academic cooperation network among the subjects. All noun phrases in the titles were clustered and analyzed to generate hot research subject terms based on the clustering relationship. The calculation of co-occurrence coefficients between noun phrases showed that the research focus varies across different toxicants (drugs). For example, the stability of synthetic cathinones is more concerned, while synthetic opioids are more concerned with the study of overdose death and postmortem distribution problems. It focused on four research directions according to the research hot topics, including new psychoactive substances, hair analysis, dried matrix spot technology and mass spectrometry technology, and explores research progress and future pathways in these fields in the light of scientific research practices.

Key words: bibliometric, forensic toxicology, new psychoactive substance, hair analysis, dried matrix spot

摘要： 对近十年国际法医毒物学领域的整体发展趋势进行文献计量分析，考察了学术生产力较高、学术影响力较大的作者、机构、国家，绘制了各主体之间的学术合作网络。对题录中所有名词短语通过共现分析工具进行聚类分析，生成基于聚类关系的研究热点主题词。计算名词短语之间的共现系数表明，不同毒物（毒品）的研究重心有所不同。例如合成卡西酮类物质的研究较关注稳定性问题，而合成阿片类物质的研究则更关注过量致死与死后分布问题。根据研究热点主题词，聚焦于新精神活性物质、毛发分析、干基质斑技术和质谱分析技术四个研究方向，结合科研实践挖掘这些领域取得的研究进展与未来路径。
