摘要
旬阳县位于陕西省东南部,是我国汞的主要产地。汞矿开采历史悠久,历史遗留的土法炼汞点多、废矿渣乱堆乱放,汞矿采选冶炼过程中,由于汞矿石外露,输送过程中造成的物料抛洒及扬尘随着雨水、风蚀进入环境中,废弃炼汞厂汞排放的废气、废水和废渣,长年积累,已对周围土壤造成污染。
Xunyang County is located in the southeastern part of Shaanxi Province and is the main producing area of mercury in China.Mercury mining has a long history.There are many mercury refining sites in the history,and waste slag is scattered.In the process of gold mining and smelting,due to the exposure of mercury ore,the materials in the transportation process are thrown,dust is generated,and the rain and wind erosion enter.In the environment,waste gas,waste water and waste residue from mercury in waste mercury refining plants have accumulated over the years and have caused pollution to the surrounding soil.
