According to the investigation data of PHC content in Jiaozhou Bay, China from 1979 to 1983, the content, sources, horizontal, vertical and seasonal distribution, and transfer laws of PHC in the water of the bay were analyzed on spatial scale, and the processes of pollution sources,land transfer, sedimentation, and water transfer of PHC in Jiaozhou Bay were discussed on temporal scale. These laws and changing processes could provide theoretical foundation for studies on water transfer of PHC and other heavy metals.
