| 1 | 人类活动对日本神西湖汞污染的影响显示文摘日本西部岛根县的神西湖(Lake Jinzai)是一个半咸湖,这里没有都市和工业污染物的点源排放。为了查明其Hg污染程度,从湖心取了一条长3.6 m的岩心剖面,研究了其中的Hg和其它微量元素(Fe、Mn、Zn、Cu、Pb、Ni、Cr、Co)。由沉积物中^(137)Cs放谢性确定了沉积速率。研究表明,沉积物中Fe、Cu浓度相对增加始于150 a前,而其它金属则始于本世纪初。Hg最高含量(303 ng/g)出现在岩心样50~55 cm高处,工业时代前的Hg浓度则见于岩心最下部。显然,重大Hg污染事件发生在50年代中叶至60年代。地球化学变量间相关性分析揭示,Hg与Fe氧化物、Fe水化物以及Fe硫化物(Fe相)包粒相关,Zn、Cu、Pb与Fe相相关,Cr、Co则与Mn相相关。 | R.L.Rohana Chandrajith 裴效松 | 1996 | 地质科学译丛1996，13，2： | 5 |
