摘要
根据1979~1984年(缺少1980年)的胶州湾水域调查资料,分析有机农药六六六(HCH)在胶州湾水域的含量大小、年份变化和季节变化。研究结果表明:在1979~1984年(缺1980年)期间,在胶州湾水体中HCH的含量逐年都在减少。在1983年,中国禁止HCH的使用,在禁用后,水体中HCH的含量全部低于一类海水的水质标准。在禁用后,水体中HCH的含量很低,几乎没有季节变化。因此,中国禁止HCH的使用对环境的改善取得显著的成效。
Based on data from the investigations of Jiaozhou bay waters from 1979 to 1984(lacking 1980),the contents and yearly and seasonal variations of HCH in Jiaozhou Bay were analyzed.The results showed that in Jiaozhou bay the content of HCH decreased annually during from 1979 to 1984.In 1983,application of HCH was prohibited in China.After the prohibition,the content of HCH in the waters was very low,and was less than the Grade I standard of National Seawater Quality Standard(NSQS),and had almost no seasonal variation.Therefore,prohibition of HCH by China has led to positive environmental impact.
