| 中文摘要: |
| 白令海的海洋生物资源丰富,是全球海洋生物的重要栖息地之一。开展白令海海洋生物体内的痕量金属富集作用具有较重要价值,但目前有关研究海域底栖生物该方面研究还为数甚少。本文于2008年8月中国第3次北极科学考察期间,在西白令海海域采集10类底栖生物(共120个样品),采用原子吸收光谱法测定生物体内的Cd、Cu、Cr、Zn含量。结果表明,蟹类肌肉组织中的Cd、Cr、Zn含量显著高于鱼类和头足类,盒螺肌肉中Cu含量在所有被测生物中最高,且不同组织内Cd、Cu、Cr、Zn含量从高到低的顺序均为肝胰腺>肌肉>生殖腺。生物富集系数的计算结果表明,白令海底栖生物对Zn、Cu元素具有较大的富集能力。 |
| 英文摘要: |
| The Bering Sea is an area of high biological productivity, with large populations of sea-birds, demersal and pelagic fishes, so it seemed desirable to assess the bioaccumulation of trace metals in the marine organisms from this area. However, few data on trace metal concentrations are available for the benthopelagic organisms from the Bering Sea till now. Ten specimens of benthos (including 120 biological samples) were collected in the western Bering Sea in August 2008 during the 3rd Chinese National Arctic Research Expeditions, and the concentration of Cd, Cu, Cr and Zn determined using atomic absorption spectrometry. Zn, Cr and Cd concentrations in muscle tissues of the crab species were much higher than those from fish and cephalopod species, and the highest concentration of Cu was observed in the muscle tissues of Cylichna nucleoli. The results showed a similar hierarchy for Zn, Cr, Cd and Cu concentrations among different tissues as follows: hepatopancreas >muscle tissue >gonad. Bioconcentration factors indicated that benthic organisms had high accumulation abilities for Zn and Cu. |
