【摘要】 依据2007年2月、5月对龙口湾近岸海域表层海水的温度、盐度、pH值、悬浮物(SS)、溶解氧(DO)、化学需氧量(COD)、亚硝酸盐(NO2--N)、硝酸盐(NO3--N)、铵氮(NH4+-N)、活性磷酸盐(PO43--P)、铜(Cu)、铅(Pb)、锌(Zn)、镉(Cd)、石油类等理化指标测定结果,应用单因子污染指数和富营养化指数对该海域的水质进行了分析和评价。结果显示,该海域表层海水中各污染要素质量浓度大致呈现由SW部海域向NE部海域递增的趋势,无机氮、活性磷酸盐及石油类为该海域的主要污染物,该海域总体营养水平较高,处于磷限制的潜在性富营养水平。更多还原

【Abstract】 Based on the data obtained in the coastal waters of the Longkou Bay,water temperature,salinity,pH,suspended substance,DO,COD,NO-2-N,NO-3-N,NH+4-N,PO3-4-P,Cu,Pb,Zn,Cd,and petroleums are detected to analyze and evaluate the coastal water quality by means of the single-factor pollution index and the eutrophication index.It is shown in the results that the mass concentrations of the pollutants are lower in the southwest of the coastal waters and become higher toward the northeast.The main pollutants are inorganic nitrogen,inorganic phosphorus,and petroleums.The coastal waters are rich of nutrients.It is better to particularly restrict phosphorus-use to prevent its potential eutrophication.更多还原
