Description	Sorption and biotransformation of arsenate by water bloom forming cyanobacterial biomass (predominantly Microcystis sp.) has been studied in this work. Biomass coming from Brno dam reservoir was cultivated in river water enriched by arsenate for 6 days. Water and aqueous extracts of biomass were subjected to anion exchange chromatographic analysis (Hamilton PRP X-100 column, ammonium acetate mobile phase pH 6.0) with ICP-MS detection. Quantitative reduction of arsenate to arsenite was observed followed by biomethylation mainly to dimethylarsinate (DMA).
