Abstract

Massive cyanobacterial water blooms and production of toxins (cyanotoxins) have become a worldwide problem. 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 suggests the occurrence of cylindrospermopsin in the Czech Republic for the first time (particularly, 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 μg/l as recommended by the World Health Organization.
