Three-dimensional simulations of mercury cycling in the Mediterranean Sea

摘要

Circulation in the Mediterranean Sea has been simulated by the 3D model PCFLOW3D for four seasons, based on measured temperature/salinity fields. Data on mercury input from larger rivers and some Hg-enriched point sources were obtained from UNEP reports. Distribution of total mercury in the Mediterranean Sea has been calculated by the same model for the period of two years, simulating separately the transport of dissolved and paniculate mercury. Suspended sediment transport was also simulated. The model predicts high mercury concentrations near locations of major river inflow.
