| 摘要: |
| 根据1985~1989 年的胶州湾水域调查资料, 分析有机农药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1985~1989 年期间, 水体中HCH 的含量全部低于一类海水的水质标准, 保持着一类海水水质。在HCH 含量方面, 在胶州湾整个水域, 水质非常的清洁。HCH 在胶州湾水体中的含量是很低的0.2095 μg/L, 就出现了胶州湾水体中HCH含量在年份的变化是振荡的变化, 其变化范围为: 0.002~0.2095 μg/L。而且在一年中季节变化就没有了。然而, 水体中HCH 的低含量却是长期存在的, 很难从环境中消失。 |

| Abstract: |
| Based on data from an investigation of Jiaozhou Bay waters from 1985 to 1989, the concentrations and annual, and seasonal variations of hexachlorocyclohexane (HCH) in Jiaozhou Bay were analyzed. The results showed that HCH concentrations satisfied the Grade I National Seawater Quality Standard (NSQS) and the Grade I water quality from 1985 to 1989 after the prohibition of HCH use in China was maintained. Based on HCH concentrations, the whole of Jiaozhou Bay could be considered to have very clean, water. The HCH concentrations were very low, and oscillated, within the range of 0.002–0.2095 μg/L, resulting in a disappearance of the seasonal variation in one year. However, this low background HCH concentration in Jiaozhou Bay waters will persist for a long time as they are, very difficult to remove from the environment. |
