The status of organic pollution of six river segments was investigated during dry season. Organic compounds in the water samples were analyzed using liquid-liquid extraction and GC-MS qualitative/quantitative method. A total of 34 organic compounds were detected with relatively high concentrations for alkanes, fatty acids, phthalate and alcohols. Comparative analysis of organic compounds in these river segments showed that the number of organic compounds detected in south river samples was small and the concentrations were generally low. In addition, the abundance of the main pollutant- Phthalate was low,which showed that south river was relatively lightly polluted. West river I samples had similar number and amounts of organic compounds to the south river samples, but contained relatively high concentrations of Phthalate, which indicated that west river was moderately polluted. Water samples from the east, north and west river Ⅲ had large quantities of organic compounds and high concentrations, including abundant phthalate, which indicated that these river segments were relatively severely polluted.
