The Relationship and Influencing Factors Water-Gas Interface Mercury Emission Flux and Water Suspended Mercury of a Gold Mining Area River

In order to study the coupling relationship and its influencing factors river water-air interface emission flux of mercury with the rivers of mercury, based on the small Qin Lingjin mining area shuangqiao river as the research object, with field investigation, monitoring and indoor suspended adsorption desorption experiments means. Obtaining the datas about winter and summer season water, suspended solids, gaseous mercury and hydrological and meteorological conditions of river. The result show that water velocity and Quantity of flow, relative pressure were positively correlated with the river-gas interface mercury exchange flux; humidity and rivers of mercury volatilize were positively correlated in summer, the winter not no monitoring data shows that correlation; river volatile mercury is restricted in air and water temperatures, Water temperature affect the suspended solids of mercury adsorption desorption, the higher the temperature, the lower adsorption. Mercury not easily soluble in river water, suspended matter mercury concentration as positively related with river-gas interface mercury emission flux. Research results will enrich the river mercury migration transformation rule and pollution prevention and control work.
