| 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)在胶州湾水域的水平分布和污染源变化。研究结果表明: 在1979～1984 年(缺1980 年)期间, 由于我国在1983 年禁止HCH 的使用, 胶州湾水域HCH 的污染源发生了很大变化, 分为3 种类型: 重度污染源、轻度污染源以及没有污染源, 并用3 个模型框图来表示, 展示了HCH 污染源的变化过程。在HCH 的禁用前后, HCH 污染源的含量、水平分布、输入方式和污染程度都发生了变化。然而, 唯一不变是HCH 的污染源是面污染源, 甚至是在没有污染源情况下, 进入胶州湾水域的HCH 来源也是面来源。 |

| Abstract: |
| By investigation data in Jiaozhou bay waters from 1979 to 1984(absent of 1980), the horizontal distribution and pollution source change of HCH in Jiaozhou Bay are analyzed. The results showed that in Jiaozhou bay the pollution source of HCH greately changed because of the prohibition of HCH use in China in 1983 during from 1979 to 1984(absent of 1980). The pollution source change was divided into three types: heavy pollution source, light pollution source and no pollution source, which was respectively expressed with three model sketchs, exhibiting the change process of HCH pollution sources. Before and after the prohibition, largely changed were the content, horizontal distribution, import way and pollution souce degree. However, only area pollution source changed in the HCH pollution source, even in the case of no pollution, the HCH souce into the Jiaozhou bay waters was area souce. |
