Preliminary Discussion on the Sea Water Quality Status in the 2008 Olympics Boat-sailing Field and Adjacent Area.
A cruise of survey in the 2008 Olympics boat-sailing field and adjacent area was carried out on August 28th, 2003. Preliminarily analysis on the eutrophication status was made on the basis of the content of dissolved inorganic nitrogen (DIN), dissolved inorganic phosphate (PO4-P)，dissolved oxygen(DO) and chemical oxygen demand (COD) as well. The results indicated that in most of the survey area, water quality was in accordance with the 1st class National Seawater Standard except the average concentration of petroleum hydrocarbon which was beyond the 2nd class National Seawater Standard. The concentrations of PO4-P as well as DIN were mainly influenced by the runoff or drainage from lands, with a comparatively higher concentration in the coastal areas from the Fushan Bay to the Shilaoren bathing beach. The distribution of eutrophication index (EI) showed that part of the survey area was in a state of slight eutrophication. The eutrophication was mostly influenced by the land runoff or drainage and related factors. The sea water quality of the Olympic boat-sailing field was fine and just slightly polluted on the whole.
