| 根据2006年6月~2007年10月对北黄海海区表层海水中石油烃污染状况进行的四季现场调查，探讨了该海区的石油烃含量的季节变化及分布特征。结果表明，北黄海石油烃的年平均浓度为0.050 mg/L，符合国家一（二）类海水水质标准。其中，夏季石油烃平均浓度最高（0.099 mg/L），符合国家三类海水水质标准；春季（0.022 mg/L）和秋季（0.027 mg/L）较低，符合国家一（二）类海水水质标准；冬季居中（0.051 mg/L），略超过国家一（二）类海水水质标准。从调查海区石油烃平面分布来看，高值区主要在渤海海峡附近、港口附近及北黄海东部靠近朝鲜的海区（包括鸭绿江口附近），长山群岛附近海域为相对低值区。 |
| 英文摘要: |
| An investigation on concentrations of dissolved petroleum hydrocarbons (DPH) in the surface water of northern Yellow Sea of China has been conducted in spring, summer, autumn, and winter during Jun. 2006~Oct. 2007. Based on the acquired data, the seasonal variations and distribution characteristics were analyzed. The results showed that the annual mean concentration of DPH in the surveyed area was 0.050 mg/L, within the concentration limit of Grade I (Ⅱ) according to National Seawater Standard. The seawater was slightly contaminated and the concentrations of DPH varied seasonally. The highest average concentration (0.099 mg/L) appeared in summer, which was classified as Grade Ⅲ seawater. The average values in spring (0.022 mg/L) and autumn (0.027 mg/L) were much lower, within the concentration limit of the Grade I (Ⅱ) seawater. The average value in winter (0.051 mg/L) was slightly beyond the concentration limit of Grade I (Ⅱ) seawater. Based on the data of the seasonal variation and distribution characteristics, it was concluded that the concentrations of DPH in Bohai Strait, ports and the northernern Yellow Sea were relatively higher, and those near Changshan Islands were lower. |
