- 摘要：采用新的现场分离系统分析了东南极海12个表层海水样及32个剖面样中硒及各主要溶存形态的含量,发现总硒含量高于其它各大洋,这可能与特殊的极地生态环境对其形态的影响有关。Se(Ⅵ)拟可作为水团指示剂。
- Abstract：Total concentrations, as well as four species,of selenium in 12 profiles and 32 surfcewater samples collected from the Eastern Antarctic Ocean,souther Ocean in Summer of 1990 and 1991 were analyzed. The newly-developed in situ sampling system was used for the fractionation. The results showed that the total concentration of the selenium is higher than that previously reported.The geochemical cycling of the selenium might be affected by the regional processes which are different from those in other oceans, and rnay be described using a three-compartment model.
