Oceanic residence time of mercury
摘要
The annual flux of mercury to the oceans was estimated by using the mercury concentrations in river water, precipitation, and by estimating the amount of mercury released into the environment from chlor-alkali production. The annual fluxes from precipitation, river water and human activities are 5 X lOB g, 1.2 X lOB g and 0.3x 10Bg, respectively. The annual mercury deposition rate was estimated by using the mercury concentration in marine sediments and the sedimentation rate, resulting in a flux of 8.0x IOSg of mercury to marine sediments. From these results the residence time of mercury in the oceans was calculated to be ca. 1 X 104 years.
