摘要: 目的:通过分析吉林省查干湖丰水期和枯水期的15项金属元素和15项稀土元素(REE)的含量,对查干湖的水质进行初步评价。方法:按照相关的国家标准,应用ICP-MS、ICP-AES、AFS和AAS对查干湖丰水期和枯水期的地表水样品进行检测,对丰水期和枯水期的数据进行比较。结果:丰水期和枯水期各项金属元素的含量都较低,均低于我国《地表水环境质量标准》Ⅲ类水域水质标准。丰水期和枯水期相比,Hg、Ba、U的变化规律不显著(P>0.05),其余各项元素指标的浓度丰水期比枯水期略高(P>0.05);Be、Co、Ni、Cu、Zn、Se、Pb丰水期高于枯水期(P<0.05)。结论:查干湖的水质状态较好,而且不易因为食物链的生物富集作用而导致砷、汞、铅等重金属元素中毒,查干湖湿地区没有受到重工业污染源的污染。

Abstract: To evaluate the water quality of Chagan Lake by analyzing 15 metal elements and 15 rare earth elements (REE) contents in rainfall season and rainless season of Chagan Lake of Jilin province.Methods In  accordance with the relevant national standards,ICP-MS,ICP-AES,AAS and AFS were performed to determine the water guality of Chagan Lake in rainfall season and rainless season,the data of rainfall season and rainless was compared.Results The metal element contents in rainfall season and rainless season were lower than the water quality standard of class Ⅲ Surface Water Quality Standards in China.The variation of the con tents of Hg,Ba,U in rainfull season compared with rainless season was not significant(P>0.05),the contents of the remaining elements in the rainfall season were slightly higher than those in rainless season(P>0.05);the contents o f Be,Co,Ni,Cu,Zn,Se,Pb in rainfall season were higher than those in rainless season and had statistically significant difference (P<0.05). Conclusion The water quality state of Chagan Lake is good,and it is unease to cause the poison of As,Hg,Pb and other heavy metals induced by of bioaccumulation role of the food chain ,the result shows that Chagan Lake wetland areas have not been polluted with heavy industrial pollution sources.
