摘要
为弄清土壤中的含汞量与土壤中岩石粒径大小的关系,采集了内蒙古通辽市的130个第四系松散地层土样,用热释法测量了土壤中的含汞量,结果表明,土壤含汞量的大小主要受区域地质条件和构造活动强度的控制,同一地质区域内土壤含汞量的高低受岩石颗粒粒径大小的影响,岩石颗粒小,土壤含汞量高,反之,则相反。
In order to understanding the relation between the Murcury content and the size in soil,the 130 samples of Quaternary loose soil from Tongliao city are collected,the Murcury contents in the soil samples are tested by the thermoluminescence.The test results show that the Murcury contents in soil are controled by the regional geological condition and the tectonic activity,the Murcury content in soil of same site are influenced by the size of soil,the soil of the large size contains high Murcury content,otherwise the content is low.
