Ecotoxicological evaluation of biochar via organism Folsomia candida
 Marcinko, Juraj ; Procházková, Petra (oponent) ; Zlámalová Gargošová, Helena (vedoucí práce)
The aim of this bachelor thesis was to ecotoxicologically evaluate selected biochar samples and to assess, using a test organism, the possible long-term and short-term effects on soil invertebrates. One of the possible uses of biomass is to convert it into biochar with subsequent application to soil. Soil fauna may be affected after biochar application, therefore ecotoxicological tests in a contact arrangement were chosen. Folsomia candida was used as the test organism. Short-term effects were recorded through escape tests, specifically low abundance of organisms in samples (I) and (T). Significant preference of organisms was observed for sample (O). Samples (I) and (T) had a further impact on the survival of organisms and on the quality of reproduction, where in some cases this caused a resolute impact. Sample (O), at different concentration levels, had no effect on the test organisms. The results of these tests approximate how soil invertebrates could be affected after biochar application.
