作者于1984年夏季测定了黄河口及邻近海域表层沉积物中Zn、Fe、Mn、Cu及有机质的含量。结果表明:河口及近岸海域表层沉积物中Zn含量较高Zn与有机质、Fe、Mn、中值粒径呈正相关,相关系数为: γ_(Zn-Org)=0.704 γ_(Zn-Fe)=0.858 γ_(Zn-Mn)=0.802 γ_(Zn-Mdφ)=0.906 本文提出表层沉积物中Zn的地球化学形式、含量及其分布。在调查区表层沉积物中总锌平均含量为80.47mg/kg,其中可交换部分为0.48%,碳酸盐结合部分占5.16%,铁—锰氧化物结合部分占15.5%,有机物结合部分占9.15%,残渣部分为69.3%。
The authors measured the contents of Zn, Fe, Mn, Cu and organic matter in surface sediments in the Yellow River Estuary and its adjacent waters in the summer of 1984. The results showed that there was a positive correlation between Zn and organic matter, Fe, Mn and median grain size in surface sediments of estuarine and coastal waters. The correlation coefficients were: γ_ (Zn_Org) = 0.704 γ_ (Zn_Fe) = 0.858 γ_ (Zn-Mn) = 0.802 γ_ (Zn-Mdφ) = 0.906 This paper presents the geochemical forms, contents and distribution of Zn in surface sediments. In the survey area, the average content of total zinc in surface sediments was 80.47mg / kg, of which the exchangeable fraction was 0.48%, the carbonate bound fraction was 5.16%, the iron-manganese oxide bound fraction was 15.5% and the organic fraction was 9.15 %, The residue part is 69.3%.
