Kolarova, I. | Beklova, M. | Vavrova, M. (Veterinarni a Farmaceuticka Univ., Brno (Czech Republic))
The toxicity of Morava river sediments from Velehrad and Kostelany in the Czech Republic was evaluated in a series of bioassays on Sinapis alba, Raphidocelis subcapitata, Lemna minor, Daphnia magna and Poecilia reticulata. No toxic effect of river sediments was observed on the studied parameters, i.e. root length of Sinapis alba, cell number of Raphidocelis subcapitata, leaf number of Lemna minor, mortality or immobilisation of Daphnia magna, and mortality or changes in behaviour of Poecilia reticulata. The growth of autotrophic organisms was stimulated, which indicated that nutrient concentration was high.
