胶州湾表层水中石油烃、化学耗氧量和金属铬的分布及污染现状分析

根据1987年5月和8月2次调查的结果,分析了胶州湾表层水中的石油烃、化学耗氧量和金属铬的分布和污染现状,并与1980年前后的历史资料进行了比较。结果表明,黄岛新建大型输油码头基本不引起其邻近海域的石油烃污染,并且胶州湾水体中的石油烃污染较以前有所改善,而金属铬污染却有所增加,但其分布形式都基本未变,石油烃和金属铬污染均无季节变化。而该湾化学耗氧量的分布和量值有明显的季节变化。除少数河口区外,胶州湾绝大多数海域的石油烃、化学耗氧量和金属铬含量均满足渔业水质要求。

POLLUTION STATUS ANALYSIS OF PETROLEUM HYDROCARBONS, CHEMICAL OXYGEN DEMAND AND CHROME AND ITS DISTRIBUTION IN THE SURFACE WATER IN THE JIAOZHOU BAY

This paper dealt with the results obtained by investigation in May and August, and analysed pollution status of petroleum hydrocarbons, chemical oxygen demand and chrome and their distribution in the surface water in the Jiaozhou Bay. The results were also compared with historical data collected around 1980. The results indicated that the newly-built large-scale oil terminal at Huangdao didn't basically cause oil pollution in the adjacent waters. Pollution status had been improved to some extent as compared with that of before 1980, but chrome content had somewhat increased and its distribution didn't be changed basically. No seasonal changes were observed for chrome and oil pulltttion. They were affected by organic waste water from the shrimp pond because there was no obviously seasonal changes in the value of chemical oxygen demand and its distribution. The contents of petroleum hydrocarbons, chemical oxygen demand and chrome all meet the fishery water quality standard for major water areas in this Bay except a few estuary areas.
