| 摘要: |
| 在枯水期和丰水期，对秦皇岛市15个典型入海排污口污水进行生物效应监测，选用发光细菌（费歇尔弧菌）、藻类（中肋骨条藻）、甲壳类（卤虫）、鱼类（海水青鳉幼鱼）4种不同的生物毒性测试生物对污水进行短期急性毒性测试。结果表明：排海污水的毒性大小易受雨水稀释影响；海水青鳉幼鱼对污水最为敏感，其次为卤虫和中肋骨条藻，费歇尔弧菌敏感性最低。对排海污水毒性评估结果与理化指标的相关性分析进一步表明，仅仅依靠理化指标来评估污水的环境影响具有局限性。 |

| Abstract: |
| This study monitored the biological effects of 15 typical sewage outlets discharged into the sea in Qinhuangdao city. Monitoring is carried out during dry season and wet season. Four different test organisms: luminescent bacteria (Vibrio fischeri), algae (Skeletonema costatum), crustaceans (Artemia) and fish (Juvenile medaka)were selected and short term acute toxicity tests on sewage were conducted. The results show that the toxicity of sewage discharged into the sea is easily affected by rainwater dilution. In addition, Juvenile medaka are the most sensitive to sewage, followed by Artemia and Skeletonema costatum, and Vibrio fischeri are the least sensitive. The correlation analysis between the toxicity evaluation results of this study and the currently measured physical and chemical indexes further proves that it is limited to rely solely on physical and chemical indexes to evaluate the environmental impact of sewage. |
