摘要：The investigation dataset on Plumbum (Pb) in surface waters in Jiaozhou Bay in May and August 1990 studied the migration paths of Pb from source to ocean. The results unveiled that the major sources were port wharf, river flow, atmosphere deposition and marine current, whose source strengths were 13.39 μg L−1, 12.97 μg L−1, 11.01 μg L−1 and 10.82 μg L−1, respectively. This paper revealed that there were three different migration paths which were described by a block diagram model. Finally, the migration laws of Pb from sources to ocean were defined that the loss of Pb contents were increasing along with the increasing of migration path. Ocean was the sink of Pb. During the migration path from source to sink, a part of Pb was storing in water body, while another part was settling and fixing in sea bottom.
