Abstract

Understanding the settlement process of Cr in marine bay is essential to pollution control and environmental remediation. Jiaozhou Bay is a semi-closed bay located in Shandong Province, China. This paper analyzed the seasonal variations of Cr in bottom waters, and identified the settlement process. Results showed that Cr contents in bottom waters in spring, summer and autumn were 0.06-3.78 g L-1, 0.03-2.11 g L-1 and 0.27-1.58 g L-1, respectively, indicating order of autumn > summer > spring. By means of the settlement process, there were four high Cr content regions in bottom waters of Jiaozhou Bay, i.e., 1) coastal waters in the west of the bay, 2) estuary of rivers in the east of the bay, 3) the center of the bay, and 4) the bay mouth. The input of Cr and the geomorphology of the bay were the mainly determining the settlement process of Cr, leading to the high Cr content regions mentioned above. Cr in surface waters was rapidly settling to bottom waters, and was accumulating in the bottom.
