摘要
根据2007年5月和8月三都澳渔业水域2个航次的水环境监测资料,分析了澳内渔业水域水环境质量状况,并采用单因子指标对调查区水域进行环境质量评价.结果显示:DO、COD、pH、石油类、总汞、砷、铜、铅、镉、锌各因子的污染指数均小于1.0,表明调查水域水质未受该因子污染;无机氮和活性磷酸盐分别有66.7%、33.3%测站的污染指数大于1.0,表明调查水域水质已受该因子污染,二者是目前澳内的主要污染物,且富营养化趋势明显存在.
Based on the water environment monitoring data of two voyages in May and August,2007,this paper analyzes the status of environment quality of the fisheries area of Sandu Bay and assesses environmental quality of waters of the survey area with Single-factor Index Method.The results showed that： pollution index of DO,COD,pH,Petroleum,total-Hg,As,Cu,Pb,Cd and Zn was less than 1.0;pollution index of DIN at 66.7% of the stations and pollution index of PO4-P at 33.3% of the stations were greater than 1.0,DIN and PO4-P were the main pollutants in the Bay and the eutrophication trends were significant.
