摘要：
The concentration and chemical speciation of metal elements(K,Na,Ca,Mg and Sr) in sediments were investigated from upstream of the Pearl River,China.The result showed that Total concentrations of metal elements in sediments were in wide range,the ranges of K,Na,Ca,Mg and Sr were 3 016-12 742,135-565,6 794-12 968,2 060-6 229 and 4.01-35.4 mg/kg in sediments.K was dominated by the residual fraction,Sr was dominated by weak acid soluble fraction.The bioavailability of Sr in the area is higher than K.The order of bioavailability was Sr>Na>Ca>Mg>K.
