Microcystins in drinking water in the Czech Republic
Babica, Pavel ; Bláha, Luděk ; Kohoutek, Jiří ; Adamovský, Ondřej ; Bláhová, Lucie ; Maršálek, Blahoslav
The paper summarizes results of microcystin analyses in drinking waters in the Czech Republic. Microcystins were detected in 36% of samples collected in 1999-2005 from 40 drinking water treatment plants. Microcystins were detected in 27% of samples of treated water and 9% of samples had concentrations of microcystins above 1 mug/L (i.e. higher than hygienic limit for microcystin-LR). The maximal detected concentration of microcystin in treated water reached up to 7.8 mug/L.
Information for customers: analyses of microcystins in water, cyanobacterial biomass, plants and animal tissues
Babica, Pavel ; Bláha, Luděk ; Maršálek, Blahoslav
Information for customers: analyses of microcystins (in samples of water, cyanobacterial biomass, plants and animal tissues) in Laboratory of cyanotoxins (Centre for cyanobacteria and their toxins).
Practical experience of detection and removal of microcystins in drinking water treatment plants
Babica, Pavel ; Bláha, Luděk ; Maršálek, Blahoslav
Summary of practical experience of detection and removal of microcystins in drinking water treatment plants in the Czech republic in 1999-2005. The paper includes results of case studies of microcystin elimination in two different drinking water treatment plants.
Methods of microcystin analysis in different matrices: a review
Babica, Pavel ; Kohoutek, Jiří ; Bláha, Luděk ; Maršálek, Blahoslav
The literature review of analytical procedures and analytical methods (instrumental, immunochemical, biochemical) for detection of microcystins in different matrices (water, cyanobacterial biomass, plant and animal tissues).
Toxicity of cyanobacterial blooms for birds - experimental model with Japanese quail
Skočovská, B. ; Adamovský, Ondřej ; Pašková, V. ; Hilscherová, Klára ; Babica, Pavel ; Maršálek, Blahoslav ; Pikula, J.
Investigation of toxicity of cyanobacterial biomass (microcystin-containing) for birds. No mortalities were observed in avian dietary toxicity test (10 or 30 days of exposure) with Japanese quails, but exposure of experimental birds to cyanobacteria resulted in significant changes of histopathology, blood chemistry and biochemical markers.
Can we predict occurrence of toxic oligopeptides in Microcystis cells by microscopic analysis?
Šejnohová, Lenka ; Maršálek, Blahoslav ; Némethová, D. ; Welker, M.
Possibility of toxicity prediction of the cyanobacterium Microcystis based on morphological characteristics.

Maršálková, Eliška ; Maršálek, Blahoslav
Overview of methods and technologies for cyanotoxin removal in drinking water.
Evaluation of sediment importance for phosphorus internal load
Borovec, Jakub ; Hejzlar, Josef
Eutrophication still belongs to the serious problems waiting for solution. Phosphorus is the nutrient most often limiting the primary producers. It is well known, the improvement of water quality can be, after successful decrease of external P load, retarded by P-release from sediments. It is also necessary to realize, that the decrease of external P-load to the demanding level cannot be due to technical, political or economical reasons always possible. Measures increasing P-retention in sediments are often employed in such conditions. Many cases are known when the level of the water quality improvement remained far behind the expectations. Technical problems, still unknown mechanisms or insufficient screening followed by inadequate solution might be the reasons for the failures. The aim of this paper is to show simple decision-support system for exclusion of improper solutions and increase of the effectiveness of activities made before the rehabilitation measures realization.
