摘要
本文采用了两种粒度校正方法:≤16μm粒径外推校正法,中值粒径校正法。研究结果表明,沉积物As含量经粒度校正以后,能比较有效地反映出河口地区As的分布变化情况。
The contents of arsenic in sediments are. affected not only by the contents of arsenic in seawater but also by the grain-size, for this reason, two correction methods are discussed in this paper, I6 μm extrapolation from grain-size distribution, median diameter. After grain-size effect correction, the contents of As in sediments can really show the distribution of As in seawater.
