小窑湾海域的环境现状及其发展趋势研究

本文对小窑湾海域的水化学，沉积物和生物体化学要素含量水平和分布进行了研究。其结果为，１４种水化要素，没有一种要素超标；１２种沉积化学要素超出环境允许标准；生物体中残毒量未超过生物允许标准此湾底质受污染晃北岸西部地段，并受控于水动力因素，最衙得出该湾环境变化几点认识。

Study on the Environmental Status quo and Going Trend in Xiaoyao Bay of North Yellow Sea

The distributive feature and the level of the chemical factors contents in the water column,sediments and marine organisms in Xiaoyao Bay have been studied in the paper,The results show that.1) the contents of fifteen factors in water column,such as salintv,pH,DO,COD,NH4-N,NO2-N,NO3-N,PO4-P,Cu,Zn,Pb,Cd,As and oil were the normal concentration levels (A class).2) the metals (Zn,Cu) and Sulphide were beyond the environmental standard in the sediments of north offshore area,the rest pH,Eh,organic,total nitrogen,Pb,Cd,Mn,and oil,at the normal levels,3) the levels of eight factors in the marine organisms (linne') Cu,Zn,Pb,Cd,Cr,Hg,As,666 have not exceeded the molluse content criteria. 4) The pollution in the bay was attributed from the northern coastal zone,and under the control of the water dynamics. Finally,the comprehensive utilization and environmental evolution are also expounded.
