Abstract

In the original language

We report comparison of the immunochemical ELISA determination with the liquid chromatography/ mass spectrometry (LC/MS) method for CYN analyses in the samples from the Czech Republic, Central Europe. Results of the ELISA and LC/MS showed good qualitative agreement. However, concentrations determined by ELISA were systematically higher than concentrations determined by LC/MS. Differences between methods could be attributed to matrix effects (both in ELISA and LC/MS) or ELISA cross-reactivity with other unidentified derivatives of CYN. Our study demonstrates for the first time occurrence of CYN in the Central Europe.

In Czech

První celoplošná analýza obsahu cyanobakteriálního toxinu cylindrospermopsinu v povrchových vodách v České republice. Cylindrospermopsin analyzován ve vodné matrici imunochemickou (ELISA) a instrumentální metodou (LC-MS). Obě metody potvrdily jeho přítomnost ve třech lokalitách v ČR.
