Nanhauang-His stream and The Beihaung-His are located in the volcano function area, the stream has introduction of the sulphur gas and hot spring water of volcano, changes the environmental condition of the water body, influences the heavy metal and moves the course.There is a hot spring in area on the volcano after one The Shuang-His streams belongs to too, but the carbonic acid spring, there is less content of sulphate.Therefore, we can realize it was pH value that influenced the dissolving heavy metal to move mainly.

南磺溪与北磺溪的地区属后火山区域有喷气孔、硫气孔和温泉的存在，溪水有火山硫磺气体与温泉水的输入，改变水体的环境条件，影响到重金属迁移过程，双溪也属后火山区域有一处温泉，但属於碳酸泉，硫酸盐含量较少，由此我们可知，主要影响溶解性重金属迁移的是pH值。

Contents of Zn, Cu, Cd and Pb in Shell of oyster and offshore water from Dalian gulf, Laohu beach, Fujia Zhuang beach, Lingshui bay, Lvshun and Jinzhou are studied by Anodic Stripping Voltammetry in order to establish a relationship between offshore seawater and heavy metal content in shells. Through monitoring the seawater and shells we researched whether the shells could replace the soft tissue of oyster shells as an indicator of marine environment changes in hope of finding a more convenient and accurate carrier for monitoring marine heavy metal.
