Abstract

Based on the investigation data on cyanide in bottom waters in the bay mouth of Jiaozhou Bay in 1983, we analyzed the contents, pollution levels, and distributions of cyanide. Results showed that cyanide contents in bottom waters in 1983 were 0.02-0.34 g L-1, and were much lower than guide line of cyanide in Grade I (5.00 g L-1) of National Sea Water Quality Standard (GB 3097-1997), indicated that the pollution levels of cyanide in this bay in 1983 were very low. There were high value regions in the inside of the bay mouth, yet were low value regions in the out side of the bay mouth, indicated that there were aggregation and divergence processes of cyanide in the bay. Cyanide contents were decreasing from the inside of the bay mouth (0.06-0.34 g L-1) to the bay mouth and then the outside of the bay mouth (0.02-0.04 g L-1). The substances could be transported to everywhere even the input of cyanide was low content, and the contents of cyanide would be homogeneity in waters. These findings are strongly proving the homogeneity of the ocean.
