The use of bioindication method for assessment of industrial sewage impact on water environment

Ecotoxicology is relatively young science, which forms link between ecology and toxicology enabling investigation of toxic substances’ impact on ecosystems. Bioindication is a method in which living organisms are used as indicator. Their reaction can be a basis for assessment of general biological activity of studied system, and, as a consequence, for assessment of studied sample toxicity. With the help of bioindication, the general toxicity of studied sample may be determined, as well as the total effect of contaminations contained in sewages impact on water environment may be defined. Many tests exist, in which the bioindication method is used. In Central Mining Institute, the tests with the use of LUMIStox were conducted. This system enables to obtain repeatable and reliable results of measurements.
