基于文献计量的微塑料与阻燃剂复合污染环境健康风险研究进展分析

Research Progress of Environmental and Health Risks Caused by Combined Pollution of Microplastics and Flame Retardants Based on Bibliometrics Analysis

近年来,微塑料(microplastics,MPs)和阻燃剂(flame retardants,FRs)作为2类新污染物,二者的复合污染问题及环境健康风险受到广泛关注。本研究基于Citespace文献计量分析软件以微塑料与阻燃剂的复合污染及环境健康风险为主题进行研究态势、成果聚类、主题演化等方面的可视化分析,为后续把握该领域重点方向提供参考。研究表明,微塑料与阻燃剂复合污染及环境健康风险相关研究起步较晚但发展迅速,该领域内我国研究力量贡献较为突出;微塑料中溴代阻燃剂的环境行为、生物蓄积及毒性效应研究、海洋环境中微塑料与阻燃剂归趋研究、微塑料与阻燃剂对人体的暴露途径及健康影响等内容是此领域的主要聚焦点;微塑料和阻燃剂复合暴露毒性的分子毒理学机制以及二者与其他环境持久性有机物的互作机制是未来重点关注的方向。

Microplastics and flame retardants are two emerging pollutants.They have drawn widespread attention due to their combined environmental health risks in recent years.This study utilizes the Citespace bibliometric analysis software to visually analyze research trends,results clustering,and topic evolution related to the composite pollution and environmental health risks associated with microplastics and flame retardants.The aim is to provide a reference for forthcoming key directions in this field.Our results indicate that investigations into the composite pollution and environmental health risks of microplastics and flame retardants start late but develop rapidly.Notably,China has made notable contributions in this domain.Research in the field primarily centers on investigating the environmental behavior,bioaccumulation,and toxic effects of brominated flame retardants in microplastics,as well as exploring their fate in the marine environment and the exposure pathways and human health effects.The forthcoming attention is to unravel the molecular toxicological mechanism associated with the combined exposure toxicity of microplastics and flame retardants.Additionally,considerable focus will be devoted to investigating the interaction mechanisms between these two substances and other persistent organic compounds.
