| 摘 要： | Marine water samples, including both surface and bottom samples, were collected from the five sampling sites in Victoria Harbour during December 2004 and February 2005. The concentrations of trace metals （Cd, Co, Cr, Cu, Ni, Pb and Zn） in the suspended particulate matter （SPM） and dissolved phases as well as the Pb isotopic compositions of the suspended particulates were determined to assess the potential sources and transport pathways of metal contaminants in the harbour. The results showed that sewage discharges along the harbour dominated the SPM loadings in water, particularly in the dry season. The total concentrations of Co, Cr, Cu, Ni and Zn in water showed a close association with the SPM loadings, indicating that SPM was important in transporting these metals in the coastal environment. Dissolved phase was predominant for Cd in Victoria Harbour. The particulate phase was the major form of Pb in marine water.
