南海海南岛东北部海区春季水体油类污染现状分析评价

Analysis and Assessment on Pollution Status by Oil in Northeast of Hainan Island Sea of South China Sea in Spring

分析评价2019年春季南海海南岛东北部海区(19.50°N-21.50°N,110.50°E-112.50°E)水体油类污染现状。结果显示,调查海区39个站位的水体油类含量均符合第一类海水水质标准(≤0.050 mg/L),就海域油类平均含量高低相对比较而言,近岸海域>远岸海域;以第一类海水水质标准评价,调查海区39个站位的水体油类的单项标准指数均小于1,就海域油类评价单项标准指数高低相对比较而言,近岸海域>远岸海域。

To analyze and assess on pollution status by oil in Northeast of Hainan Island Sea of South China Sea(19.50°N-21.50°N, 110.50°E-112.50°E) in the spring of 2019 Spring. Results showed that the oil content in seawater of 39 stations in the investigated sea area all were below the standard values of first national seawater quality(≤0.050 mg/L), in terms of average oil content in sea areas, the sequence was the Offshore Sea Area > the Far Sea Area. According to the first national seawater quality assessment, the single standard index of oil in seawater of 39 stations in the investigated sea area were less than 1, in terms of average of the single standard index of oil in seawater in sea areas, the sequence was the Offshore Sea Area > the Far Sea Area.
