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.
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.
