The geochemical characteristics of heavy metals (Cd, Co, Cr, Cu, Ti, Zn) in 61 surface sediments from the Yangtze River Estuary and its adjacent East China Sea were studied. The high values of Cu, Co and Zn are distributed near the mouth of Hangzhou Bay. The high values of Cr appear near Zhoushan Archipelago. The high values of Cd appear in the Yangtze River Estuary, while Ti and Cd have high values in the open sea eastward. The order of pollution degree is Cr > Cd > Co > Zn > Ti > Cu. The enrichment degree is Cd > Cr > Zn > Co > Ti > Cu. Except for some sites, Cd is moderately enriched, but there is no severe enrichment. The main sources of human activities of the six metals include industry and shipping. Agricultural production may be another important source of human activities for Cd.
研究了长江口及其邻近东海61个表层沉积物中重金属（镉、钴、铬、铜、钛、锌）的地球化学特征。铜、钴和锌的高值分布在杭州湾口附近。铬的高值出现在舟山群岛附近。镉的高值出现在长江口，而钛和镉在向东的公海中具有高值。污染程度顺序为铬>镉>钴>锌>钛>铜。富集程度为镉>铬>锌>钴>钛>铜。除部分点位外，镉为中度富集，但无重度富集。这六种金属人类活动的主要来源包括工业和航运。农业生产可能是镉人类活动的另一个重要来源。
