New cyanobacterial metabolites with tumor promoting potencies and interaction with other toxic compounds
Bártová, Kateřina ; Kohoutek, J. ; Adamovský, Ondřej ; Bláhová, Lucie ; Hilscherová, Klára ; Babica, Pavel ; Bláha, Luděk
In this study were investigated interaction of binary mixtures of cyanobacterial extracts and anthropogenic compounds (polyaromatic hydrocarbons, polychlorinated biphenyls).
The content of microcystin in the chosen tissues at different fish species
Hlávková, J. ; Adamovský, Ondřej ; Oravec, M. ; Bláha, Luděk ; Mareš, J. ; Kopp, Radovan ; Palíková, M.
The aim of this study was to assess quantity of microcystins in muscle and hepatopancreas of different fish species (Cyprinus carpio, Oreochromis niloticus, Sander lucioperca and Esox lucius). Microcystins were detected in liver/hepatopancreas (hundreds of ng per gram of tissue) as in muscles (nanograms per gram of tissue). It seems that acumulation of microcystins in eatable parts of fishes represent only small risk for man.
Diversity and microcystins content of cyanobacteria in fish ponds (South Moravia, Czech Republic) related to fishery management intensity
Kopp, Radovan ; Ziková, Andrea ; Adamovský, Ondřej ; Brabec, T. ; Straková, L. ; Mareš, J.
During the vegetative period of the years 2005-2007 (June--October) we carried out hydrobiological and hydrochemical monitoring of selected ponds inhered in Southern Moravia in relation to different fishery management intensities. Water temperature, dissolved oxygen content, pH, conductivity and water transparency were monitored directly at taking place, N--NH4+, N--NO2-, N--NO3-, P--PO43- content and chlorophyll-a concentration were measured in hydrochemical laboratory.
Bioaccumulation of microcystin-LR in fish tissues accompanied by effects at biochemical level
Adamovský, Ondřej ; Pašková, V. ; Bláha, Luděk ; Hilscherová, Klára ; Kopp, R. ; Babica, Pavel ; Maršálek, Blahoslav
Experimental evidence on microcystin bioaccumulation and modulation of biochemical parameters related to oxidative stress and detoxication in two fish species, silver carp and common carp, after two month-exposure to microcystin producing cyanobacterial bloom in outdoor breeding tanks.
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.
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.
