摘要
2018年10月在海口湾海域设20个调查站,按《海洋监测规范》采集表层沉积物样品,用碘量法测定硫化物含量,用单因子指数法进行评价。结果表明:各测站的硫化物含量在4.76×10-6～1 764.92×10-6mg/L(干重),均值为202.53×10-6mg/L。从硫化物的平面分布来看,呈现近岸高、湾中部和湾口低的特点,高值区在龙昆沟、丘海大道泄洪沟和五源河入海排污口附近海域。除了1号、 17号和18号站,其他站的沉积物质量均满足所在海洋功能区的要求。
According to the specification of oceanographic survey,the samples of surface sediment were collected from 20 sites in the Haikou Bay in October of 2018.The sulfide contents in the samples were determined by iodimetric and evaluated by single factor index method.The results showed that the sulfide contents(dry weight counted by S2-) varied from 4.76×10-6 to 1 764.92×10-6,and the average value was 202.53×10-6.According to the spatial distribution,the values in coastal area were higher than the center and mouth of Haikou Bay.And the higher values appeared near the mouth of Longkun Drain,Qiuhaidadao Drain and Wuyuan River.Except the oil site 1,17 and site 18,the sediment quality of other stations conform the marine environmental requirements of the functional zoning.
