某金矿带双桥河河水-底泥-悬浮物中Hg含量时程分布特征
The Mercury Concentration Time and Space Characterized of Shuangqiao River in the Gold Mine Area
摘要
Abstract
In order to studying mercury conversion relation and the time empty variation in water,suspend thing and bottom silt of the river in a gold mine,the mercury time-space contest in Shuangqiao river has been analyzed by using investigation and testing data.①The monitoring data about the river water,sediment and suspended solids of shuangqiao river before mining,mining height and mining management phase have been studyed comparatively,the result governances that river water and sediment mercury content is the highest in the mining height phase,the situation has been changed in 2015,2016.The contrasting resuit of mercury content in three phases show that,the systematic monitoring inriver water,suspended thing and bottom silt can be used to evaluation present situation and future development direction of river pollution more accurately;②Aftercontrasting the mercury contents of river wate,suspend thing and bottom silt changed along the Shuangqiao river,The mercury concentration is bottom silt＞river water in the mountain,while the mercury concentration is suspend thing＞bottom silt＞river water,in the plain area with thin grain material aggrandizement and slowly water power slope,the mercury occurred as the solid form of bottom silt and suspended thing,without any water soluble states.This research result will provide some reference basis for the water environment management of mercury pollution in the gold mine area,as well as the prevention,cure and repair of damaged eco-system.关键词
