中文摘要
      为研究大气传输以及干湿沉降对偏远地区环境中有机磷酸酯(OPEs)含量及分布的影响,本研究以海螺沟景区为例,采集了海螺沟的植物和积雪样品,用气相色谱-质谱联用仪(GC-MS)定量分析了样品中7种典型有机磷酸酯[磷酸三丁酯(TnBP)、磷酸三氯乙酯(TCEP)、磷酸三氯丙酯(TCPP)、磷酸三(2,3-二氯丙基)酯(TDCPP)、磷酸三苯酯(TPhP)、磷酸三丁氧乙酯(TBEP)和磷酸三异辛酯(TEHP)]的含量及分布特征.结果表明,海螺沟景区常见的9种植物中7种OPEs(∑7OPEs)的含量(以DW计)水平在43.1~1050.8 ng·g-1之间,其中TBEP和TPhP含量最高,分别占∑7OPEs总含量的36%~70%和24%~80%.冰川积雪中主要污染物与植物中一致,TBEP含量最高,占∑7OPEs总含量的47%,其次为TPhP,占24%.采用Grads、后向轨迹模型及历史风向数据分析得出海螺沟环境显著受到人类活动扰动,其OPEs主要受来自成都方向和云南昭通与宜宾、泸州、西昌交界处方向的大气传输的影响,需要进一步研究其环境行为并加强城市污染控制.
英文摘要
      In order to study the effects of atmospheric transport and the wet/dry deposition on the content and distribution of organophosphate esters (OPEs) in remote areas, seven types of OPEs including tri-n-butyl phosphate (TnBP), tri (2-chloroethyl) phosphate (TCEP), trichloropropyl phosphate (TCPP), tridichloropropyl phosphate (TDCPP), triphenyl phosphate (TPhP), tributoxyethyl phosphate (TBEP), and tris (2-ethylhexyl) phosphate (TEHP) were analyzed in plants and snow samples in Hailuogou using gas chromatography-mass spectrometry. The results showed that the pollution levels of the seven OPEs (∑7OPEs) in the plant samples ranged from 43.1 ng·g-1 to 1050.8 ng·g-1. TBEP and TPhP were the main pollutants, accounting for 36%-70% and 24%-80% of the ∑7OPEs, respectively. The main pollutants in the snow in Hailuogou were the same as those in the plants, with TBEP dominating the profile of the ∑7OPEs at 47%, followed by TPhP at 24%. The analysis results of the grid analysis display system (Grads), backward trajectory model, and historical wind data of Hailuogou indicate that the OPEs in this region are affected mainly by atmospheric transmission from Chengdu and the junction of Yunnan Zhaotong and Yibin, Luzhou, and Xichang. The environment of Hailuogou has obviously been disturbed by human activities. It is necessary to conduct thorough investigations of its environmental behavior and to strengthen urban pollution control measures.
