摘要

According to the investigated data of Jiaozhou Bay in April,August,September and October of 1989,distribution,source and seasonal change of HCH in Jiaozhou Bay were analyzed. Results showed that HCH content changed during 0. 012 7-0. 069 8 μg /L in Jiaozhou Bay and was very low. Seen from HCH content,water in Jiaozhou Bay was cleaner,and HCH did not have seasonal change. Horizontal distribution of HCH showed that HCH was directly input into offshore water only by surface runoff,and there was no river input. HCH was area source and was from land. In Jiaozhou Bay,the maximum HCH was gradually becoming smaller,and input manner also changed. HCH migration changed from river input to river and surface runoff input to final surface runoff input.
