本文研究了2006~2007年夏、冬、春、秋4个航次北部湾（BeibuGulf）海域表层海水、大气气溶胶中的重金属和秋季航次北部湾海域表层沉积物中的重金属。首次获得了重金属在该海域不同介质中的含量、水平分布、来源及季节变化等特征。取得以下主要结果： 北部湾四个季节表层海水中重金属的Cu含量为0.14mg/L~1.03mg/L（平均0.40mg/L），Pb为0.036mg/L~2.80mg/L（平均0.46mg/L），Zn为0.33mg/L~24.02mg/L（平均8.37mg/L），Cd为0.0015mg/L~0.122mg/L（平均0.041mg/L），Cr为0.083mg/L~0.95m...In this thesis, the research was carried out to examine concentrations, distribution patterns and seasonal variation of heavy metals (Cu, Pb, Zn, Cd, Cr) in seawater and sediments, as well as (Cu, Pb, Zn, Cd, Al, Fe, V) in aerosols from Beibu Gulf in four cruises during 2006-2007. The main conclusions were as following: Concentrations of heavy metals in surface seawater from Beibu Gulf were in th...学位：理学硕士院系专业：海洋与环境学院海洋学系_海洋化学学号：2005130215
