Abstract

Based on investigation data on petroleum hydrocarbon (PHC) in June, July, September and October 1980 in bottom waters in Jiaozhou Bay, we analyzed the content and distribution of PHC. Results showed that PHC contents in June, July, September and October 1980 in bottom waters were 0.028-0.147 mg L-1 and were meeting Grade II (0.05 mg L-1) and III (0.30 mg L-1) in National Sea Water Quality Standard (GB 3097-1997). PHC contents were decreasing from the inside of the bay mouth to the bay mouth, and to the outside of the bay mouth in June, and were decreasing from the inside of the bay mouth to the open waters in September and October, yet were decreasing from the open waters to the inside of the bay mouth in July. We found that no matter from the bay to the open water of from the open water to the bay, the contents of the substances were decreasing continuously by means of vertical water’s effect.
