RESUMEN
Objective To investigate the pollution status of phthalate esters in household indoor air particles in Wuhan. Methods The indoor air particulate matter PM10 and PM2.5 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.
