南极麦克斯韦尔湾及邻近海域高锰酸钾指数研究

为了研究南极水域的污染状况，于１９９３年１２月～１９９４年２月对南极麦克斯韦尔湾及邻近海域的高锰酸钾指数（ＣＯＤＭｎ）的变化和分布状况进行了监测。３９个站次的测值在０．３３４～１．９５９ｍｇ／Ｌ之间，符合中国《海水水质标准》（ＧＢ３０９７－８２）第一类水质（３．０００ｍｇ／Ｌ）要求。各考察站附近的测值高；长城湾内高于湾口及湾外。分析了湾内、湾口和湾外在１９９３年１２月、１９９４年１月及２月的变化情况和原因；对ＣＯＤＭｎ的主要来源进行了研究分析；并对南极长城站及邻近海域的环境保护和研究提出了建议。

THE CONTENT OF COD Mn OF THE GREAT WALL BAY AND ADJACENT SEA AREAS,ANTARCTICA

During 1993.12￣1994.2, the COD Mn of the Great Wall Bay, Antarctica and its adjacent sea areas was investigated. The COD Mn of 39 stations was from 0.3342 mg/L to 1.9590mg/L; the high value was at the research stations, and the value of the inner Great Wall Bay was higher than that of the outside. The reason of the change of the COD Mn was studied; the main resource of the COD Mn was analysed.Some of the pollution comes from the research stations,but most of it may come from the living beings. The wind and wave is one of the most important factors affect the values of COD Mn . Suggestions were given to protect the environment of Antarctica.
