受沉积物粒度效应的影响,自然过程或人类活动引起的痕量元素含量的变化往往受到掩盖或弱化。为剔除该效应的影响,本文基于沉积物的粒度频率分布,分析各粒级组分对痕量元素的贡献,从而推算出整个样品中受粒度效应控制的痕量元素含量;再将其从测量值中扣除,即可剔除粒度效应对痕量元素的影响。并将校正结果与地球化学法的归一化结果进行比对,探讨本文方法的可行性及优势。 Affected by the grain size effect of sediment, natural processes or human activities caused by changes in trace element content are often covered or weakened. In order to eliminate the effect of this effect, based on the frequency distribution of sediment particle size, the contribution of each fraction to the trace elements was analyzed to calculate the trace element content controlled by the grain size effect in the whole sample. Value deducted, you can get rid of particle size effect on trace elements. The calibration results are compared with the normalized results of geochemical method, and the feasibility and advantages of this method are discussed.
