摘要：In this paper described the horizontal distributions of Petroleum hydrocarbon (PHC) in Jiaozhou Bay using investigation data on PHC in May, August and October 1991, and defined the major sources. Results showed that PHC contents in May, August and October 1991 were 0.014-0.157 mg L−1, 0.010-0.058 mg L−1 and 0.007-0.064 mg L−1, respectively. The pollution level of PHC could be considered as slight. The major sources of PHC were oil spills, wharf and river runoff, whose source strengths were 0.157 mg L−1, 0.038 mg L−1 and 0.058-0.072 mg L−1, respectively. The source inputs of PHC were showing spatial-temporal variations, and resulting in the spatial-temporal changes of PHC contents in Jiaozhou Bay.
