摘要: 采用等离子质谱法研究了稀土在珠江广州江段水体各要素中的含量、分布模式及赋存形态。结果表明,稀土在河水中以悬浮态为主。西、北江沉积物或悬浮物中稀土含量基本一致,而东江沉积物稀土明显高于西、北江,其分布模式属花岗岩的风化产物。与我国不同地带河流沉积物比较,稀土分布顺序为珠江>长江>松花江。沉积物与悬浮物中各稀土元素5种赋存形态分布比例均为残渣态有机态、铁锰氧化物态>碳酸盐态可交换态。

Abstract: The use of rare earth elements(REEs)by Chinese industry and agriculture has increased over the years,and many studies exist on its effects on soils and plants.To better understand the impact of REEs in China’s aquatic environment,we collected data from the sediments and suspended matters in both raw and filtered waters from the Guangzhou section of the Zhujiang(Pearl)River.The study area covers the lower reaches of all three branches of the Zhujiang:the Dongjiang,the Xijiang and the Beijiang.The contents of the REEs in the samples were detected by ICPMS analysis,and a speculation analysis was carried out to examine the sediments and suspended matters.

Key words: Zhujiang river,rare earth elements,geochemical characteristics
