摘要

摘要: 根据1996年8月和2003年8月对埕北油田邻近海域的调查资料,对海水中溶解氧(DO)、化学耗氧量(COD)、油类和重金属的含量,沉积物中重金属、油类、有机物、硫化物的含量以及海水与底床中生物种类、数量和密度,进行历史变化趋势分析与现状评价,结果表明,海水中石油浓度有所上升,沉积物受到了铜的污染且油类浓度持续上升,底栖生物环境已属非健康状态,底栖生物受到石油烃污染.

Abstract: On the basis of data obtained during field observation in the Chengbei Oil Field and its adjacent sea areas in August 1996 and 2003,the concent ration of DO,COD,oil and heavy metals in the seawater,content of heavy metals,oil,organic matter and sulfide levels in the surface sediments,numbers of species,biomass and abundance of marine or ganisms are studied.Assessing the marine ecological environment,and analyzing the variation trend,the results indicate that petroleum exploration led to the decline of the ecological environmental quality in the area.It is found that the concent ration of oil in seaw ater rose obviously in the past years.The copper content is high enough to contaminate the surface sediments,while the oil concent ration increases continually.The bottom habitat is unhealthy and the benthos is contaminated by petroleum hydrocarbons.
