• Description: River ecosystems represent dynamic system, where contamination of river compartments exerts significant variability in space and time. Chemical compounds occur in the environment as complex mixtures that can act through specific modes of action in organisms. Suitable tools for assessing specific biological activities in environmental samples represent screening bioassays. The present research focuses on contamination of a model river ecosystem in south-eastern part of Czech Republic. Aim of our one-year long study was to characterize temporal and spatial variability of contamination and toxicity of complex mixtures (sediments and water samples) collected from five sampling sites.This research was supported by the Czech Ministry of Education projects ENVISCREEN - NPVII 2B08036 and INCHEMBIOL 0021622412.
