| 摘 要： | 根据1979年的胶州湾水域调查资料，分析了重金属铬在胶州湾水域的分布、迁移和季节变化。研究结果表明；春季，胶州湾水城铬污染较轻，大部分海域水质状况较好，而到夏季没有受到污染。在时空分布上，春季，铬污染形成了明显的梯度，由东北向西南方向递减，从112．3μg／L降低到0．2μg／L。夏季，铬的水平分布比较均匀，表层水体铬的含量较低，范围在0．10～1．40μg／L之间波动。因此认为，1979年整个胶州湾水域的重金属铬属于面污染源。而且，当铬进入胶州湾海域后，很快吸附在水体中的悬浮颗粒上，并被水流较快地带离胶州湾水城，几乎没有在胶州湾水域表、底层留下污染痕迹。 |

| Abstract: | Based on data from the investigation in Jiaozhou bay waters in 1979, the distribution, displacement and seasonal variation of chromium in Jiaozhou bay are ana- lyzed. It is showed that in spring in Jiaozhou bay, the pollution of chromium is less, the water quality in the most of the waters is better, while in summer no pollutiion of chromium is found. The spatial-temporal distribution in pring is that the pollution degree of chromium has an obvious gradient from the northeast to the southwest in a range from 112.3 μg/L to 0. 2μg/L. In summer the horizontal distribution of chromium becomes relatively homongeneous, chromium content in surface water is relatively low and ranges between 0. 10 μg/L and 1.40μg/L. Therefore it is considered that chrominum in the whole Jiaozhou bay comes from an areal pollution source. Moreover, as soon as chromium discharged into the waters of Jiaozhou bay, it is absorbed by suspended particles in waters, and brought by water currents flowing away from the Jiaozhou bay so that very little is left in the surface and bottom waters of Jiaozhou bay. |
