Preserved Fulltext
Based on the analysis of seawater quality monitoring data, the grey predication method (GM (1, 1) model) was used to predict seawater quality in the Rigs-to-Reefs area of the Chengdao oil field. The result shows that petroleum pollutants and dissolved oxygen concentration will take on an increasing tendency from 2011 to 2015, and heavy metal Hg and Cd will be still kept at a low level. In addition, COD concentration has been gradually decreasing. On the whole, the prediction results indicate
