- 摘要：2003年1月采集广州市城区包括居民区、城区交通主干道、垃圾堆放场、休闲旅游区、商业区和工业区等20个道路灰尘样品.参照USEPA8061系列方法,研究了广州市城区道路灰尘中邻苯二甲酸酯(PhthalateEsters,PAEs)的分布特征.结果表明,道路灰尘样品中PAEs含量范围为4.48～370.42μg·g-1(干重),平均值为132.58μg·g-1(干重),TOC质量分数为14.2%～16.93%.综合商业大厦、繁华商业步行街、饮料生产厂区、城区交通主干道和农贸市场道路灰尘PAEs含量较高;DEHP、DnBP和DiBP为道路灰尘中主要的PAEs;道路灰尘中wDEHP>wDnBP>wDiBP>wDnOP>wDEP>wDMP.
- Abstract：Road dust samples of Guangzhou city were collected for analysis of Phthalate Esters (PAEs) on 11～16 Feb. 2003, that relative humidity were 60%～80% and temperature were 15℃～25℃. The concentrations and distribution characteristics of the six major PAEs in 20 roads dust samples collected in different functional districts of Guangzhou city were measured by using USEPA 8061 series methods under quality assurance (QA) and quality control (QC).The results showed that the concentrations of total PAEs in the road dust samples ranged from 4.48μg·g-1 to 370.42μg·g-1, average concentration was 132.58μg·g-1 (dry weight),and TOCwere 1.42 %～16.93 %(proportion of mass). The road dusts selected from commercial plaza, industrial district, heavy traffic highway and residential district had been heavily contaminated. The highest concentration of total PAEs in road dust sample was 370.42μg·g-1 at a new large business building. The distribution patterns of six principal PAEs that DMP, DEP, DnBP, DiBP, DnOPand DEHPin road dust samples showed the resemblance. The DEHP,DnBPand DiBPwhich were the predominance of PAEs in road dust samples were clearly observed,and the concentrations showed an order that wDEHP>wDnBP>wDiBP>wDnOP>wDEP>wDMP.
