烟台四十里湾海水养殖水域环境污染研究
Research on Seawater Environment Pollution of the Mariculture in Yantai Sishili Bay
摘要
Abstract
Based on the water quality investigation results of eight monitoring stations in the mariculture region of Sishili Bay,the seasonal changes in the concentrations of chemical oxygen demand (COD) .dissolved inorganic nitrogen (DIN) .total nitrogen(TN) .active phosphate (PO,-P) and total phosphorus (TP) were analyzed,the pollution contribution rate from marine aquaculture was estimated. Organic pollution index and eu-trophication index had been used to assess the water quality. The results showed that the concentration of chemical index was significantly higher in summer than that in spring. In comparison with the previous years,the contents of COD,DIN and PO4-P increased obviously. TN and TP concentrations exceeded the second-rate seawater standard,and TN concentration overweighed the highest of 140%. The average eutrophieation index in the bay in summer was 3.58 and the eutrophieation was much more serious in summer than that in spring. The average organic pollution index in the overall study area was 3.40 and organic pollution levels reached the level 4,which was moderately polluted.关键词
