舟山南部海域石油类污染状况调查与评价

Investigation and evaluation on petroleum hydrocarbon pollution in the south sea area of Zhoushan

摘要: 根据舟山南部海域2008年8月～2009年6月4个季度的水质石油类含量及环境因子调查监测,以及表层沉积物石油类含量、9种海洋生物石油烃含量的监测结果,分析评价结果表明:舟山南部海域水质石油类平均含量符合国家一、二类海水水质标准,但个别站位超标。石油类含量与pH、盐度、温度、DO、COD等环境因子之间相关性很差。季节分布上,冬季石油类平均含量最低,其它三个季节的差异性不显著。表层沉积物质量和海洋生物质量良好。

Abstract: The petroleum hydrocarbon pollution level was evaluated in the south sea area of Zhoushan, according to the investigation result of water, surface sediment and marine animals in Aug.2008 ~Jun.2009, the results showed that in water, the average concentrations of petroleum hydrocarbon accorded with the first and second class of the water of National Standards. The relativity between Petroleum hydrocarbon and pH, salinity, temperature, DO, COD was very small. The concentration of petroleum hydrocarbon in winter was least, other seasons had no evident difference. The quality of surface sediment and marine animals were well.
