摘　　要： 采用ICP-AES对广州珠江水体微表层与次表层中Cu、As、Zn、Cr、Pb和Cd的质量浓度进行为期一年的调查研究。结果表明:珠江广州段水体均不同程度地受到6种重金属的污染,重金属浓度的季节性变化比较明显,在春季和冬季时浓度较高,夏季时浓度较低;重金属浓度的空间变化也比较明显。除Zn外,微表层对其余5种重金属均具有较强的富集作用。 Concentrations distribution of As,Cd,Cr,Cu,Zn and Pb in the water of surface and subsurface microlayers of four locations from Guangzhou section of pearl river for one year were determined by ICP-AES.The water in Guangzhou section of pearl river was polluted by six kinds of heavy metals in different degree,and the concentrations of heavy metals obviously seasonally changed,and there was higher concentration in the spring and winter,lower in the summer,while their spatial variation were obvious too.The surface microlayer had good enrichment for these heavy metals except Zn.
