本文通过新研制的底层水采样器采集了锦州湾及其河口区底层水扣上覆海水中的悬浮颗粒物质.分析表明,该区距底5cm、25cm和50cm的临底海水与上覆海水中悬浮颗粒的粒径分布略有差异;借助~(210)Pb测年、重复水准测量以及悬浮粒子断面输入量计算等手段的综合对比,每年由河流、外海和沿岸废渣向湾内输入的悬浮颗粒物质约3.6557×10~5t;悬浮物质中某些污染物质含量与该区表层沉积物污染物含量为一个数量级.经推算,每年由河流和外海悬浮颗粒携带入湾内的4种污染物总量:锌为118.62t,铅为23.05t,镉为4.06t,汞为0.88t.它们占河口及入湾颗粒-污染物质总量的10.89%(Pb),30.01%(Zn),76.20%(Cd),61.53%(Hg).
In this paper, the newly developed bottom water sampler was collected at the bottom of Jinzhou Bay and its estuaries water suspended solids in the seawater. Analysis shows that the area from the bottom 5cm, 25cm and 50cm of the bottom seawater and overlying seawater Particle size distribution of suspended particles is slightly different. With the comprehensive comparison of ~ (210) Pb dating, repeated level measurement and calculation of input of suspended particle cross section, the annual input of suspended particulate matter from rivers, offshore sea and coastal waste into the bay About 3.6557 × 10 ~ 5t.The content of some pollutants in suspended matter and the surface sediment in this area is an order of magnitude.It is estimated that the total amount of four pollutants carried by the suspended particles in the river and in the open sea into the bay each year is zinc (Pb) of 23.60t, cadmium of 4.06t and mercury of 0.88t, accounting for 10.89% (Pb), 30.01% (Zn) and 76.20% (Cd) of the total particulate matter- 61.53% (Hg).
