Abstract:

WT5BZ]During the CHINARE 15, lake waters,ice and snow had been sampled in the Zhongshan Station and its adjacent area, Antarctica. Compared with Environmental Quality Standard for Surface Water(China,GB3838 88),their COD Mn had been divided into three groups. Many of them (about 56%) are under the first type of quality standard, and the other are under the second and the third type,37% and 7%, respectively. The most important factor affecting the values of COD Mn was natural source, and the pollution coming from the human activity was not serious. The values of COD Mn for lake water showed the situation of biological growth, the content of organic substance, salinity and the extent of oxidation and reduction for water. On the other hand, the COD Mn of fresh snow is the index of the atmospheric pollution for this area.
