The Disjunction Effect of Marine Bay Mouth to Zn

摘要

Based on the investigation data on Zn in bottom waters in the bay mouth of Jiaozhou Bay in May, September and October in 1983, were analyzed the contents and distributions of Zn. Results showed that Zn contents in bottom waters in May, September and October in the bay mouth of Jiaozhou Bay in 1983 were 1.24-120.66 μg L~(-1), 6.67-17.78μg L~(-1) and 4.72-20.44 μg L~(-1), respectively. By means of the disjunction effect, no matter the substances were in the inner side or outside of the bay mouth in any marine bays, their contents would be decreasing once the waters were passing through the bay mouth. We called this phenomenon as 'Yang's phenomenon'. Zn contents in May, September and October in the outside of the bay mouth could be considered as high, low and moderate, while in the inner side of the bay mouth were all low, which were providing strong evidences for disjunction effect of marine bay mouth to Zn.
