摘要
本文以1989年8月调查资料为基础,论述了大窑湾疏浚物倾倒区的水化学要素(pH、盐度、DO、COD、浊度)、营养盐(NO_2-N、NO_3-N、NH_4-N、PO_4-P、SiO_3-Si)和重金属(Cu、Zn、Pb、Cd)等污染物分布特征;分析了水质、底质的环境状况及潮流的影响。从环境地球化学观点探讨了该疏浚物倾倒区选择的科学性。
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.
