• Description: In this report we present results of cyanotoxins analyses (peptide microcystins, alkaloid cylindrospermopsin) in the Czech Republic reservoirs using HPLC-PDA and ELISA. Our study revealed occurence of cylindrospermopsin in the Czech Republic for the first time in water blooms containing Aphanizomenon klebahnii. We also discuss human health risks associated with microcystins in relation to the drinking water guideline value of 1.0 microgram per litre as recommended by the World Health Organization. Our study demonstrates development of methods, their applications for analyses of both cell-bound (biomass) and dissolved (extracellular) cyanotoxins and evaluation of microcystin health risks.
