英文摘要	Surficial sediment samples were collected from three rivers and six canals in Tianjin, China and analyzed for petroleum hydrocarbons. Chemical compositions and distribution patterns, as well as possible sources, of the petroleum hydrocarbons in the sediments were discussed. A series of petroleum hydrocarbons, including n-alkanes, isoprenoid alkanes, anteiso-alkanes, alkyl hexamethylene, hopanes and steranes were detected in the samples. The concentration of petroleum hydrocarbons varied in a wide range of 0.072-3.000 mg g(-1) in the surficial sediment of the rivers and canals in Tianjin. In the samples studied, the total concentrations of petroleum hydrocarbons in the sediment samples from North Canal, South Canal, and G3 segment of South Sewage Canal were higher than those from Hai River, South Sewage Canal and North Sewage Canal. Accumulation of pollutants in the sediments from reaches close to urban area was also observed. The PHC spatial variability is mostly affected by many local inputs. The main sources of petroleum hydrocarbons in the sediment in Tianjin were considered to be petroleum importation and biochemical degradation of organisms, including cuticular of aquatic vegetation and algae.
