摘　　要：利用吹扫捕集-GC-MS检测了邕江南宁段以及南宁市有代表性的5条城市内河中的挥发性有机物(VOCs)。结果表明,邕江南宁段检出3种VOCs,总含量为1.43～4.30μg/L。城市内河检出了22种VOCs,其中大桥冲、朝阳溪污染较为严重,VOCs总含量分别为82.43μg/L和35.00μg/L,其特征污染物分别为卤代烃和单环芳香族类。和国内其他地区水源水中检出的VOCs含量相比,邕江南宁段的VOCs污染水平较低,而南宁城市内河的VOCs污染处于中等水平。大量未经处理的城市生活污水、工业废水排放以及垃圾沥滤是造成南宁城市内河VOCs污染的重要因素。建议GB3838-2002加强对水体中VOCs的控制。Volatile organic compounds （VOCs） in water from industrial and urban wastewater in Nanning, Guangxi Prefecture were analyzed. Samples were prepared by purge and trap technique and analyzed by GC/MS. Results showed that three kinds of VOCs were detected in Yongjiang River with total concentrations of VOCs in the range from 1.43μg/L to 4.30μg/L. 22 kinds of VOCs were detected in urban wastewater with total concentrations of VOCs of 82.43μg/L and 35.00μg/L at two sections. Major pollutants in water were chlorinated hydrocarbons and benzene substituted. Source of the pollutants and pollution status in water were analyzed.
