The flux of river active material flowing into the sea: Preliminary achievements
River is a bridge between terrene and ocean. It is very important to study the flux of river active material flowing into the sea for current ecological geochemical evaluation. We have chosen 35 major rivers flowing into the sea in Eastern China and collected the samples of suspended particulate matter (SPM), filtered water and bed mud both in dry seasons and wet periods. By analysing these samples and using the runoff data of these rivers, we calculated the annual flux of major heavy metals and nutritive elements flowing into the sea for each river and for total terrestrial rivers. Furthermore, we determined the proportion of the quantity of elements migrating to the sea in water-soluble form to that in SPM form. This study provides the reference data for the research on sea-land interactions and for shallow water ecological geochemical evaluation.
