福建东部近海生物中稀土元素的生态化学特征

在福建东部海域16个海湾采集了近海生物鱼、虾、贝壳、藻4大类26小类128个样品,用ICP-MS法测定15种稀土元素的含量,结果表明,轻、重稀土元素存在较大的分镏作用,明显富集轻稀土元素,即轻稀土元素的生物学效应更为明显,鱼类等近海生物稀土元素配分模式总体上与海水和世界页岩稀土元素配分模式接近。稀土元素沿福建东部海域食物链的迁移传递没有表现出明显的生物放大作用。

Ecological Chemistry of Rare Earth Elements in Fujian Eastern Coastal Waters

Abstract There are collected biological fish , shrimp, shellfish and algae, four major, 26 Class, 128 samples in Fujian Eastern Coast 16 gulf region. Determination of 15 kinds REE content in samples by ICP-MS. The results showed that light and heavy rare-earth is a big role in the sub-distillation , obviously rich in light rare earth. Namely, the biological effects of light rare earth even more obvious. Distribution patterns of Fish and other neritic organism REE near to seawater and the world shale. Rare Earth Elements in eastern Fujian waters along the food chain to pass the migration did not show significant biomagnification.
