2003年胶州湾红岛海域水环境现状的初步研究

Preliminary research of current environmental situation of sea water in Hongdao area of Jiaozhou Bay in 2003

根据2003年10月底和11中旬对红岛海域的大面积调查资料 ,对该海域的水质资源进行了初步研究。调查结果表明,无论是大潮还是小潮 ,海水中的pH、溶解氧、化学需氧量、大肠菌群等项目的量值比较均匀,达《海水水质标准》GB3097-1997“第二类”标准;石油类未检出 ;无机氮全部超标;PO43 -P浓度在13、14、15、17监测站位超标 ;评价区各站位海洋沉积物中有机碳、石油类和硫化物均符合第一类海洋沉积物评价标准要求。

To the large area survey of the Hongdao sea area according to the end of October of 2003 and 11 the middle ten dayses, have carried on preliminary research to water quality resources in this sea area. The investigation result shows: Regardless of spring tide or neap tide, pH, dissolve oxygen , chemical oxygen demand of sea water,, large intestine fungus group,etc. quantity of project value relatively more even, reaches GB3097-1997“second kind ” standard of “ sea water standard water ”. The petroleum has not been examined out . Inorganic nitrogen all exceed standard; PO43--P density monitors and stands the location and exceeds standard on the 13th , the 14th , the 15th , the 17th; Organic carbon, petroleum and sulpHide accord with the first type marine sedimentary evaluation criterion request in the marine sedimentary in every station location of appraising area.
