Abstract

Toxicity of municipal waste water observed by means of Vibrio fischeri proved a primary dependence between the content of organics and inhibition. A linear dependence between COD and inhibition determined by means of Vibrio fischeri was established. In 30 days following sampling organic matter was degraded and the value of inhibition fell from 80 % to 27.67 %. This value corresponds to the real impact of micropollutants (risk elements, organic micropollutants) on inhibition. The content of risk elements in municipal waste water implies that the values are significantly higher than EC50 defined for Daphnia magna. Risk element ecotoxicity is affected by the form of occurrence and it is thus probable that there are risk elements predominantly in the form of complexes in sewage water.

用费氏弧菌评价城市污水毒性

用费氏弧菌对城市污水的毒性进行了观察，证明了有机物含量与抑制作用之间的主要依赖关系。用费氏弧菌测定COD与抑菌率呈线性关系。采样后30 d有机物降解，抑制率从80%下降到27.67%。这个值对应于微污染物(风险要素、有机微污染物)对抑制作用的实际影响。城市污水中危险元素的含量明显高于大水蚤的EC50。危险因素生态毒性受发生形式的影响，因此很可能在污水中主要以复合体的形式存在危险因素。

期刊介绍： International Journal of Energy, Environment, and Economics publishes original research papers that shed light on the interaction between the utilization of energy and the environment, as well as the economic aspects involved with this utilization. The Journal is a vehicle for an international exchange and dissemination of ideas in the multidisciplinary field of energy-environment-economics between research scientists, engineers, economists, policy makers, and others concerned about these issues. The emphasis will be placed on original work, either in the area of scientific or engineering development, or in the area of technological, environmental, economic, or social feasibility. Shorter communications are also invited. The Journal will carry reviews on important issues, which may be invited by the Editors or submitted in the normal way.
