【 摘 要 】

Many bays have been polluted by Cr due to the rapid increasing of industry, hence understanding the temporal change trends and seasonal patterns is essential to pollution control and environmental remediation. Jiaozhou Bay is a semi-closed bay located in Shandong Province, China. This paper analyzed the annual changes and seasonal variations of Cr in Jiaozhou Bay in 1979-1983. Results showed that for annual changes, Cr contents were showing decreasing trend. For seasonal variations, Cr contents were in order of spring > summer > autumn. In generally, the pollution level of Cr contents in the early stage of China's Reform and Opening-up was still low. These results were meaningful as basic information for pollution control and environmental remediation in this Bay.
