摘要
本文根据1988年泰山湾调查资料,对该湾表层沉积物中有机质、重金属等8项化学要素进行了地球化学研究.结果表明,该湾表层沉积物的化学成分主要来源于(?)江径流携带的陆源物质,其分布呈北部和西部高,并向东南部递减的趋势。潮流是影响该湾化学要素分布的重要因素.有机质与多数元素有明显的正相关.污染物质含量较低.
In this paper,the geochemical features of surface sediments in the Dongshan Bay, Fujian are discussed based on the observed data in the periods of Oct. and Nov. 1988. The results show that the source of the chemical composition in the surface sediments is majorly contributed by Zhangjiang River runoff. The distribution trend of the contents of chemical compositions decreases from the head to the Bay mouth, with tidal currents as the major controlling factor. There exists an evident positive correlation between the organic matter and most chemical elements. The contents of the pollutants in the Dongshan Bay are relatively low. The mass fractions of organic matter,sulphide,Cu,Pb,Zn.Cd respectively are 1.12%,66. 0×10^(-6),17. 3×10^(-6),11. 6×10^(-6),91. 2×10^(-6) and 0.066×10^(-6).
