厦门海域表层沉积物石油类含量分布与评价

Distribution and assessment of oil contents in the surface sediments from Xiamen sea area

通过2016年8月开展的厦门海域表层沉积物中石油类含量调查,分析了厦门海域表层沉积物石油类的含量水平与分布情况。结果表明:本次调查厦门海域表层沉积物中石油类含量范围在(6.6~1 762.5)×10^(-6)之间,平均值为350.5×10^(-6);石油类含量呈现明显的分布特点:五缘湾海域至五通湾口区域的石油类含量最高,其次为九龙江口中部海域、鼓浪屿东南侧至招银港区、厦门东部水道小部分区域和五通湾口北侧海域,其余海域的沉积物质量较好,这与厦门近年来航运发展、西海域整治和五缘湾海域周边的开发建设有关。

This paper analyzed the oil level and distribution of surface sediments in Xiamen sea area based on the survey data of August 2016. The result showed that the oil contents ranged from 6. 6 × 10^(-6)to 1 762. 5 ×10^(-6)with a mean value of 350. 5 × 10^(-6). The result showed obvious distribution characteristics,the degree of oil contamination ranked from high to low was Wuyuan Bay sea area to Wutong Bay area,the middle area of Jiulong River Estuary,southeast area of Kulangsu to Zhaoyin Harbor area,a small area of Xiamen Eastern Bay and north side of Wutong Bay Estuary,respectively. The rest of Xiamen sea area indicated good sediments quality. All of which were related to the development of shipping,the conservation of western sea area and the construction of Wuyuan Bay in Xiamen recent years.
