Biogeochemical cycle of arsenic and calculating the enrichment factor by using Li element

摘要

In this study, the biogeochemical cycle of arsenic in the Bosporus and the Golden Horn, which have a two-layer stratified structure, was investigated and the dominant feature in this cycle was observed to be the anthropogenic (domestic + industrial) activities. On the contrary, in the rural areas which are far from human activities, such as Igneada, the seawater-atmosphere interchange can be observed evidently in the periods covering the primary production.
