Abstract

A Computer Simulation of the Anthropogenic Mercury Accumulation in the Environment A contribution to subproject MEPOP M. Sofiev Stroiteley str., 4-1-18, Moscow, 117311, Russia Introduction One of the important features of Hg is the high evaporation capability of some of mercury-containing compounds. This results in its appearance in the pollution cycle: emission - atmospheric transport - deposition - partial fixation/re-emission. According to available information, only about 1-2 % of the depositions onto the oceans is fixed in the bottom layers (Mason et al, 1995). For terrestrial systems this estimate varies from 20 % up to 80 % (Johnson and Lindberg, 1995), (Mason et ai, 1995). In case of small permanent fixation there is a possibility of accumulation of reactive mercury in the environment. In particular, this results in high air concentrations, which cannot be explained by observed emiss
