在对南黄海进行的研究中,我们曾提出可以通过确定海域重金属背景值的方法,也可以通过综合利用重金属与有机碳、与铁等成分的相关性及重金属相互间的相关性或比例关系的方法来判断海洋沉积物中某些重金属的含量是否异常。由于不同粒度组成的样品难以对比,故“背景值方法”的应用受到限制。而利用元素相关性的方法则较灵活,适用性较广,然而在
In the study of the South Yellow Sea, we have put forward a method that can determine the background value of heavy metals in the sea area, and also can comprehensively utilize the correlation between heavy metals and organic carbon, iron and other components and the correlation or proportion between heavy metals Method to determine the content of some heavy metals in marine sediments is abnormal. Due to the difficulty of comparing samples of different particle sizes, the application of “background value method” is limited. The use of elemental correlation method is more flexible, more applicable, however
