| Abstract: | Based on the results of investigation in 1987, the distributive characteristics of chemical factor in water column in Da Yao Bay, as pH, Salinity, DO, COD Turbidity, Nutrient(NO_2-N, NO_3-N, NH_4-N, PO_4-P, SiO_Si), heavy metals (Cu, Zn, Pb, Cd) and other contaminants and so on, are discussed in this paper. The environmental situation of water column and sediment and the effcts of tidal current is described. From the piont of view of environmental geochemistry, the scientific properties of choice of dump reqion of the dredged material is studied. |
