摘　　要：根据珠江（广州河段）沉积物中Ａｓ（Ｔ），Ａｓ（Ⅲ），Ａｓ（Ⅴ），ＭＭＡ，ＤＭＡ含量与Ｆｅ，Ａｌ，Ｋ，Ｃａ，Ｍｇ及有机碳含量，研究了南亚热带近河口区沉积物中Ａｓ形态的存在特征，并计算ＡＳ形态间及与其它元素间的相关性，从而说明ＡＳ形态在河口区的存在及迁移特征。According to the data of concentrations of As (Ⅲ), As (Ⅴ) , MMA, DMA, and Fe, Al, K, Ca, Mg as well as organic carbon in the .sediments of the Zhujiang River (Guangzhou Section), the characteristics of arsenic species, and regression equations between any two As species, as well as As species and other material are studied. From these study results, a model of the existence and migration of As species in the sediment of the estuary are suggested.
