Characterizing spatial distribution and sources of heavy metals in the soils from mining-smelting activities in Shuikoushan,Hunan Province,China

引用

Journal of Environmental Sciences 2009年第9期21卷 1230-1236页

作者： WEI Chaoyang WANG Cheng yang linsheng Institute of Geographic Sciences and Natural Resources Research Chinese Academy of Sciences Beijing 100101 China. Graduate University of the Chinese Academy of Sciences Beijing 100049 China

The spatial variation of heavy metals in the soils in Shuikoushan mining-smelting area, Hunan Province, China, was investigated using multivariate and geo-statistic analysis. A total of 106 composite soil samples were collected in an area of about 100 km^2. Concentrations of total As, Cd, Pb, Zn, Cu and Cr were measured using inductively coupled plasma mass spectrometry （ICP-MS）. Arsenic and Pb were found to have a common source, indicating the same sources and spreading processes, such as aerosols and airborne particulates from smelting chimneys. Airborne sources from smelting chimneys contributed greatly to Cd in the area, which demonstrated the same dispersion pattern as As and Pb. However, two hot spots of Cd around smelters were possibly enlarged by wastewaters, demonstrating another important source of Cd in Shuikouhsan. Geo-statistic interpolated mapping demonstrated that hotspots of Zn were only found proximal to the large smelters, suggesting that Zn primarily came from the chimneys of larger smelters. The major Cu hot-spots appeared closely to the tailing dam, indicating that weathering and leaching of tailings were the major sources of Cu contamination in Shuikoushan. Our findings indicated that airborne volatile particles and aerosols contributed the most to As, Cd, Pb, Zn and Cu contamination, while Cd and Cu may also derive from the discharge of wastewater from smelters and the leaching of tailings, respectively,

北极热融湖作为多年冻土区典型热喀斯特景观之一,其分布和变化规律深刻影响着区域的生态植被、水文和碳循环过程。然而,对于整个北极热融湖分布特征和变化机制的理解仍然不足,为此,本文基于荟萃分析和数理统计方法,对热融湖的分布规律和变化机制展开研究。结果表明,北极热融湖的分布和变化具有较强的时空异质性,且与多年冻土条件、岩石土壤类型、地下冰含量和土壤温度等密切相关。大部分北极热融湖分布在连续多年冻土区、地下冰含量高于10%、平均土壤温度在-4℃以上且存在一定垂向土壤温度差异的具有特定岩石和土壤类型的地区,而不同环境条件下的热融湖变化趋势存在差异。总体上,北极热融湖的变化过程包括初始形成、中期扩张和晚期萎缩三大阶段,且受到水量与水热平衡的双重影响。热融湖作为反映多年冻土退化和气候环境变化的重要指示,对北极生态系统碳循环、水文过程和生态环境变化等均具有深远影响。

In order to investigate the correlation between the prevalence of Kashin-Back disease(KBD)and Se concentrations,natural soil samples and cultivated soil samples were collected from southeastern Tibet,China;and the soil Se concentrations were measured by atomic fluorescent *** was found that the mean Se concentrations of natural soil samples in KBD areas,from the first layer to the third layer,were 0.17 mg/kg,0.11 mg/kg,and 0.10 mg/kg,respectively,and in nondisease areas were 0.21 mg/kg,0.24 mg/kg,and 0.13mg/kg,*** mean Se concentrations of cultivated soil samples were 0.10 mg/kg in KBD areas and 0.23 mg/kg in non-disease areas,*** Se concentrations in KBD areas were lower than that in non-disease areas,and the mean concentrations of soil Se in Tibet were lower than the average of China(0.29 mg/kg).Therefore,there is a close relationship between soil Se concentrations and KBD in *** studies should be concentrated on the impacts of Se deficiency in soils and its relationship with Se concentrations in food-grain and the human body in Tibet areas.

作者： ZHANG Fei yang linsheng LUO Xiao Institute of Geographic Sciences and Natural Resources Research Chinese Academy of Sciences University of Chinese Academy of Sciences Culture and Tourism Department of Henan Province

With the construction of Grand Canal Culture Belt being upgraded to a national strategy,the authors used GIS and other analytical techniques to give an overview of 2,834 recreational resource points distributed in 49 prefecture-level administrative units of eight provinces or cities along the Grand Canal Culture Belt,analyzed the features of their quantitative and spatial distribution,finding that:(ⅰ) the recreational resources along the Grand Canal are spatially related to the major river systems,lakes and arteries of communication;(ⅱ) the recreational resources along the Grand Canal are generally distinguished by a spatial agglomeration of "two poles and two subcenters",in which the natural recreational resources are distributed in the pattern of "three points and one line" while the cultural recreational resources are distributed with a notable feature of *** that basis,the authors proposed several suggestions about the utilization of recreational resources along the Grand Canal Culture Belt:(ⅰ) Establishing a system of diversified recreational products by adapting to local conditions;(ⅱ) building national scenic byways along the Grand Canal by relying on major river systems and arteries of communication;(ⅲ) giving priority to the development of four recreational sections of the Grand Canal and foster core growth poles.
