The results showed that PHC content in the bottom water of Jiaozhou Bay varied from 0.028 to 0.147 mg/L. from April to November （except for May） during 1980 -1981, indicating that the bottom water was polluted slightly by PHC. PHC content was affect- ed by the vertical water body effect, so that the minimum of PHC content in the bottom water changed stably. In addition, there were no obvious seasonal variations in PHC content in the bottom water. It reveals that PHC brought by human activity was more than that transported by rivers, so PHC pollution caused by human activity was serious. From the inside water to the outside water, PHC content decreased gradually in April and Au- gust but increased in November, showing the sedimentation process of PHC. The sedimentation process of PHC showed the migration paths of PHC in Jiaozhou Bay in time and space.展开更多
