英文摘要	This paper analyzed the contents and distributions of As in Jiaozhou Bay in 1982. Results showed that As's contents in bottom waters in coastal waters in the southwest of the bay and the bay mouth in Jiaozhou Bay in July and October 1982 were 0.88-4.48 mu g L-1 and 0.84-1.16 mu g L-1, respectively. As's contents were much lower than the guide line of Grade I, and the pollution level of As in bottom waters in Jiaozhou Bay in 1982 was still very slight. There was high value region in coastal waters in the southwest of the bay in July 1982 (4.48 mu g L-1), while in October 1982 high value region was in the bay mouth (1.16 mu g L-1). The source input of As from overland runoff in the southwest was strong in July, resulted in relative high value region in surface waters in coastal waters in the southwest of the bay, and therefore resulted in high value region in bottom waters in same region by means of rapid sedimentation of As. October was wet season and there was little As input to the bay, resulted in low As's contents in surface waters, as well as bottom waters. At any time, the terrigenous As was foremost transported to surface waters, and was subsided to sea bottom through water body by vertical water's effect. Hence, the high value regions of As's contents in surface and bottom waters had characteristic of consistency in Jiaozhou Bay.
