本文对黄海中南部10个沉积物样品和东海北部24个沉积物样品用等离子光谱做了Ba、Be、Co、Cr、Ga、Li、Mn、Nb、Ni、P、Pb、Sr、V、Zn、Y和Yb的分析,并对该区沉积物中元素的丰度和不同类型沉积物中微量元素的分布规律做了研究。通过对区内微量元素与主要元素的相关图解分析表明,大多数微量元素与主要元素Al、Mg、K呈正相关,其高值区与粘土沉积物相一致,低值区与粉砂质沉积物相吻合;Be、Sr、Mn的高含量与粘土沉积物无关
In this paper, Ba, Be, Co, Cr, Ga, Li, Mn, Nb, Ni, P, Pb, Sr, V and Zn were determined by plasma spectroscopy on 10 sediments in the central and southern Yellow Sea and 24 sediments in the northern East China Sea , Y and Yb, and studied the abundance of elements in the sediments and the distribution of trace elements in different types of sediments. The correlation analysis of trace elements and major elements in the area shows that most trace elements are positively correlated with Al, Mg and K, and the high value areas are consistent with the clay sediments. The low value areas and silty sediments Coincide; the high content of Be, Sr and Mn has nothing to do with clay sediments
