摘要:
提要:将城市道路表土样品进行粒度分级(全样、>63μm、63~30μm、30~11μm和<11μm),测定了各粒级组分的微量元素和稀土元素组成。结果显示,微量元素在不同粒级组分中的变化程度按照以下顺序依次递增:Sr

Abstract:
Abstract:The samples of urban road surface soils were collected from Harbin City of Heilongjiang Province and divided into different grain size fractions (bulk sample, >63μm, 63-30μm, 30-11μm and <11μm). These samples were analyzed to obtain the composition of trace elements and rare earth elements (REE). The results indicate that the variation degree of trace elements in different size fractions increases in order of Sr
