Based on the investigation data of mercury (Hg) in waters in Jiaozhou bay during time peroids of 1979 to 1985 (absent of 1984), this paper tried to analysis the seasonal variations of Hg in Jiaozhou Bay, to reveal the transfer process of Hg, and to provide basis for decision-making of pollution control. Results showed that, there was indistint seasonal variations of Hg content, due to anthropogenic discharge was the major source of Hg, which was not static, but depended on industrial adjustment. The land transfer process of Hg could be divided into three major processes: 1) human discharges of Hg to soil, waters, and atmosphere, etc., 2) Hg is washouted and delivered into streams, and 3) Hg is transferred to ocean via river channel runoff. In order to reconcile economic growth with environmental protection, we should have to improve the use ratio of Hg, and to reduce the discharge load of Hg.
