摘　　要：目的了解武汉市居民住宅室内空气颗粒物中邻苯二甲酸酯污染水平。方法采集武汉市居民住宅室内空气颗粒物PM 10、PM 2.5,采用GC/MS法分析15种邻苯二甲酸酯的物质浓度水平。结果共检测出DMP、DEP、DiBP、DBP、DEHP 5种邻苯二甲酸酯,其中DiBP、DBP和DEHP检出率为100%,DMP和DEP部分检出。结论武汉市居民住宅室内空气颗粒物中邻苯二甲酸污染广泛存在,DiBP、DBP和DEHP为主要污染物,装修材料和塑料生活用品均为重要污染源,其对健康的危害不容忽视。Objective To investigate the pollution status of phthalate esters in household indoor air particles in Wuhan.Methods The indoor air particulate matter PM 10 and PM 2.5 from residential houses in Wuhan were collected.The concentrations of 15 phthalate esters were determined by gas chromatography-mass spectrometry(GC-MS).Results A total of 5 phthalates were detected,including DMP,DEP,DiBP,DBP,and DEHP.The detection rate of DiBP,DBP and DEHP was 100%,while DMP and DEP were detected in only some of the samples.Conclusion Phthalate esters pollution was widespread in indoor air particles of residential houses in Wuhan.DiBP,DBP and DEHP were the main pollutants.Decoration materials and plastic household articles were important sources of the phthalate esters pollution,and their impact as a health hazard needs attention.
