Transfer Processes of Cyanide in Jiaozhou Bay

Abstract:

This paper analyzed the seasonal and vertical variations of cyanide in Jiaozhou Bay, and tried to reveal the transfer processes based on investigation data in different seasons in 1982. Results showed that cyanide contents in surface waters were showing obvious seasonal variations, and were in orders of spring < summer < autumn, due to the inputs of cyanide were mainly occurred in wet season. The vertical variations seem to be not regular, and the influences of cyanide contents in surface waters to bottom waters were not significant, because the degradation of cyanide were rapid in summer and early autumn, leading to most of the cyanide was degraded before or in the process of sedimentation.
