【摘要】：采用气相色谱-质谱联用仪定量分析了高校和居民住宅各室内环境灰尘中7种典型有机磷酸酯(OPEs)的浓度及分布,发现Tn BP、TCPP、TPh P检出率较高,空调灰尘的OPEs检出率为100%,而超市灰尘中OPEs均未检出;Σ7OPEs浓度范围为317.44~2566.97ng/g,低于发达国家.体育馆、寝室、教室、复印店人群活动频繁的区域灰尘中Σ7OPEs的浓度较高(1836.85~2566.97ng/g),停车场中的浓度相对较低(317.44ng/g).高校室内灰尘中以苯基磷酸酯(56%)为主,TPh P的平均浓度为937.26ng/g,而居民住宅内则以氯代磷酸酯为主(60%),平均浓度为448.12ng/g,以TCPP为主要单体.成人通过室内灰尘摄入OPEs的日均暴露剂量为0.60ng/(kg·d)(以体重计),儿童的日均暴露剂量为2.51ng/(kg·d)(以体重计),儿童的日暴露剂量明显高于成人,主要以手-口摄入为主要途径.
[Abstract]:Gas chromatography-mass spectrometry (GC-MS) was used to quantitatively analyze the concentration and distribution of seven typical organophosphate esters (OPEs) in the indoor dust of colleges and residential buildings. The results showed that the detection rate of TnBP- TCPP- TPhP was high. The detection rate of opes in air conditioning dust was 100, but none in supermarket dust was detected, and 危 7 OPEs concentration range was 317.44 ~ 2566.97 ng / g, which was lower than that in developed countries. The concentrations of 危 7OPEs in the dust of the area where the people in the gymnasium, dormitory, classroom and photocopying shop are frequently active are relatively high (1836.85) 2566.97ng / g, and the concentration in the parking lot is relatively low (317.44ng / g / g). The average concentration of TPHP in the indoor dust of colleges and universities was 937.26ng / g, while the average concentration of chlorophosphate was 448.12ng / g and TCPP was the main monomer. The average daily exposure dose of adults to opes through indoor dust was 0.60ng/(kg DX (measured by body weight, and that of children by 2.51ng/(kg dl). The daily exposure dose of children was significantly higher than that of adults, and the main route was hand-mouth intake.
