Migration Paths of PHC in Jiaozhou Bay

Abstract

This paper analyzed the sources and migration paths of Petroleum hydrocarbon (PHC) in Jiaozhou Bay in 1987. Results showed that PHC contents in May, July and November 1987 in surface waters in Jiaozhou Bay were 0.014-0.060 mg L-1 , 0.016-0.066 mg L-1 and 0.030-0.091 mg L-1 , respectively. The pollution levels of PHC in this bay were still slight in 1987. The major PHC sources in Jiaozhou Bay in 1987 were river flow and oil port, whose source strengths were 0.066 mg L-1 and 0.060-0.091 mg L-1 , respectively. The migration paths of PHC from different sources were also different since the source strengths and geographic locations of these sources were different. In general, different countermeasures should be provided to different sources of PHC.
