研究了中国东部11条主要入海河流颗粒物(悬浮物和<63μm表层沉积物)中17种常量和微量元素的含量及其地域差异。在此基础上,首次估计了我国河流颗粒物的平均元素组成。最后,根据提供的中国河流颗粒物元素组成资料和文献中对世界主要河流颗粒物元素组成的研究结果,对全球河流颗粒物的平均元素组成进行了新的估计。
The contents of 17 macronutrients and trace elements in 11 major sea-going rivers (suspended solids and <63μm surface sediments) from eastern China were studied and their regional differences were also studied. On this basis, the average elemental composition of river particulate matter in China is estimated for the first time. Finally, the average elemental composition of the global river particulate matter is estimated based on the available information on the elemental composition of the river's particulate matter in China and the literature on the elemental composition of the world's major rivers.
