摘　　要：根据1986年4、7和10月的胶州湾水域调查资料,通过对有机农药HCH在胶州湾水域的分布、来源和季节变化的分析,研究结果表明:HCH含量在整个胶州湾水域都非常低,在这1 a中都<0.100μg/L,在胶州湾水域HCH含量都优于国家一类海水水质标准,水质在HCH含量方面更加清洁;水体中HCH的表层含量已经没有季节变化,这表明在胶州湾周围,雨量、地表径流和河流的大小变化对HCH含量变化没有重要影响。在水体中HCH含量的垂直分布表明:水体中表层与底层HCH的水平分布状况不一致,只有HCH的表、底层含量相接近。自从1983年禁用HCH后,水体中HCH的含量全部达到一类海水的水质标准,在1985年以后,水体中HCH的含量都是优于一类海水的水质标准。因此,国家制定的海水水质标准在HCH含量方面需要修改,以适应新的环境变化。Based on data from the investigation in Jiaozhou Bay waters in April,July and October 1986,the distributions,source and seasonal variations of HCH in Jiaozhou Bay are analyzed.It is showed that HCH content in Jiaozhou Bay was very low and less than 0.100μg/L in this year,and better than StandardⅠof the sea water quality,and the water quality with less HCH was very clean;and that the seasonal variations of the HCH content in Jiaozhou Bay waters were not obvious and it was not influenced by the seasonal variations of the rainfall,the runoffs and rivers.It is also learnt from the vertical distributions of the HCH content in the whole bay waters that the horizontal distribution pattern of the HCH content at surface was not consistent with that at bottom,but the HCH content values at surface and bottom were very close to each other.Since the prohibition of HCH in 1983,all the HCH contents in the waters have reached StandardⅠof the sea water quality,and since 1985,all the HCH contents in the waters have become better than StandardⅠof the sea water quality.Therefore,the sea water quality national standards about the HCH need revising in order to meet requirements suitabe to the new environment change.
