摘　　要：近期研究表明,部分有机发光材料(Organic Light-Emitting Materials,OLEMs)具有环境持久性和生物富集性。为明确OLEMs对人体健康的潜在危害,本研究通过专利检索,建立了1988种OLEMs的化学品清单,并基于化学品分类和标签数据库(Classification and Labelling Inventory,C&L清单)收录的94种OLEMs的人体健康危害分类与标签信息,构建定量构效关系(Quantitative Structure Property Relationship,QSPR)模型,应用欧氏距离、分子描述符标准化和核密度估计的方法定义模型应用域,对C&L清单未收录的1894种OLEMs的接触和吸入危害性进行预测。结果表明,1652种OLEMs可能通过接触对人体健康造成危害,1612种OLEMs可能通过吸入对人体健康造成危害。本研究为优先控制化学品识别和新化学物质环境管理提供了理论依据。Recent studies have shown that some Organic Light-Emitting Materials(OLEMs)are persistent and bioaccumulative.With the aim of identifying the potential hazards of OLEMs to human health,patent retrieval was carried out to establish a list of 1988 OLEMs.A Quantitative Structure Property Relationship(QSPR)model was developed based on the information of 94 OLEMs included in the Classification and Labeling Inventory(C&L Inventory).Euclidean distance,molecular descriptor standardization and kernel density estimation were employed to define the applicability domain of the model,and the potential exposure and inhalation hazards of 1894 OLEMs that were not included in the C&L Inventory were predicted.The results indicated that 1652 OLEMs might pose hazards to human health through exposure,while 1612 OLEMs could potentially compromise human health via respiratory intake.The findings provide a theoretical basis for the identification of chemicals in prioritized control and the environmental management of emerging chemical substances.
