基于2010年10月国家自然科学基金委东海调查公共航次所获得的数据和悬浮体样品，使用IC P-A ES、IC P-M S仪器对悬浮体中的主、微量元素含量进行了测定，对悬浮体中元素组成、空间分布及其影响因素进行了研究，结果表明：长江口及邻近海域悬浮体中主量元素铝、镁、铁、钙等含量为1％～30％，含量以铝为主；微量元素镉、铬、钴、铜、锰、镍、铅、钒等含量为 n ×10-6～ n ×10-9，以锰最高；铝与铁、锰以及大部分的微量元素都有良好的相关性，指示这些主量元素以陆源输入为主和微量元素被细颗粒物质吸附为主的特征。水团对长江口及邻近海域颗粒态地球化学组分的空间分布具有重要的影响，其中铝、铁及铬、钴、铜、锰、镍、钒等元素受水团的制约更加显著。

Water samples and Conductance ,Temperature ,Depth (CTD) data have been collected through the Pub-lic Cruise of the National Research Foundation Committee ,in October ,2010.After filtering of the water samples , the total suspended matter (TSM ) has been obtained.The concentration of the main and trace elements of TSM has been tested using ICP -AES and ICP-MS ,meanwhile an elementary composition ,a spacial distribution as well as their influencing factors had also been studied.The results show that the value of main elements'(aluminium , magnesium ,ion ,calcium) concentration between 1% and 30% and aluminium is the highest ;the values of the trace elements'(cadmium ,chromium ,cobalt ,copper ,manganese ,nickel ,lead ,vanadium ) concentration are be-tween n× 10-6 and n× 10-9 and manganese is the highest.The good relationships among aluminium ,ion ,magne-sium and most trace elements indicate that the main elements are terrigenous and the trace elements are adsorbed on the land-based suspended particles.The water masses play an important role in the elementary composition of TSM ,especially aluminium ,ion and chromium ,cobalt ,copper ,manganese ,nickel ,vanadium.
