英文摘要	Using investigation data on As in Jiaozhou Bay in 1982, this paper analyzed the seasonal variation, vertical variations and horizontal distributions of As, and revealed the gravity characteristic and sedimentation of As. Results showed that As's contents in surface and bottom waters in July 1982 were 0.36-2.80 tg L-1 and 0.88-4.48 tg L-1, respectively, while in October 1982 were 0.58(-1).62 tg L-1 and 0.84-1.16 tg L-1, respectively. The pollution of As in Jiaozhou Bay 1982 was very slight. For seasonal variation, As's contents in surface waters were in order of summer>autumn, while in bottom waters were also in order of summer>autumn. In case of As contents in surface waters were relative high/low, As contents in bottom waters were also relative high/low. That was the result of gravity characteristics. The variations of As contents in surface waters were mainly determined by the changes of source input of river runoff, while the variations of As contents in bottom water were mainly determined by vertical water's effect. The sedimentaion process of As could be summarized that As was transferred to surface waters in marine bay from river runoff, was absorbed or assimilated by suspended particular matters or marine organism, and then was transported to bottom waters, and was finally fixed in sediments in sea bottom.
