- 摘要：以吹扫捕集方法定量测定了采自官厅水库库区及下游永定河水中的挥发性有机污染物的含量,共检测到26种有机污染物,其中9种属于国家地表水环境质量标准(GHZB1-1999)中特定项目.主要是卤代烃、苯系物、硝基苯、丁酮、氯乙腈等,挥发性有机污染物的总含量为19.37-100.92mgL,未检出三卤代甲烷类化合物.根据污染物浓度的空间分布规律,对上述污染物来源进行了初步分析.
- Abstract：Trace volatile organic compounds (VOCs) were identified and quantified used purge and trap gas chromatography methods. 26 VOCs were detected, in which 9 VOCs were in the list of the environmental quality standards for surface water (GHZB 1-1999). The total concentrations of VOCs were in the range from 19.37μg/L to 100.92μg/L. The major pollutants in water were chlorinated hydrocarbons, benzene substitued, nitrobenzene, chloroacetonitrile and butanone. The sources of these pollutants in water were traced according to the spatial distribution of the pollutants.
