Evaluation of eight biodegradable algicides
Jančula, Daniel; Maršálek, Blahoslav
2007 - Czech
The aim of this study was to compare the efficiency of biodegradable algicides towards laboratory cultures of algae and cyanobacteria. Toxicological effects of algicides were aslo studied on green alga Cladophora glomerata. Acording to our findings, it is necessary to regulate laboratory conditions to conditions in real ecosystem were treatment atgainst green algae should be done. Výsledkem práce bylo srovnání algicidních přípravků a jejich toxických účinků na zástupce laboratorních kmenů řas a sinic využívaných v ekotoxikologických biotestech. Toxikologické efekty přípravků byly rovněž studovány na vláknité řase Cladophora glomerata. Ze studie vyplývá, že pro přesnější stanovení toxických účinků algicidních přípravků na přirozená společenstva autotrofních organismů je nutné přïzpůsobit laboratorní uspořádání tak, aby co možná nejlépe charakterizovalo lokalitu ekosystémů, kde by mělo k zásahu proti masovému rozvoji řas dojít.

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.
2006 - Czech
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. Výzkum toxicity biomasy sinic (obsahující microcystiny) pro ptáky. V aviárním dietárním testu toxicity (10ti nebo 30ti denní expozice) s křepelkou japonskou nebyl pozorován žádný úhyn, nicméně expozice sinicím způsobila u experimentálních zvířat významné změny v histopatologii, krevních parametrech a biochemických markerech.

Microcystins in drinking water in the Czech Republic
Babica, Pavel; Bláha, Luděk; Kohoutek, Jiří; Adamovský, Ondřej; Bláhová, Lucie; Maršálek, Blahoslav
2006 - Czech
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. Příspěvek shrnuje výsledky stanovení microcystinů v pitných vodách v České republice. Microcystiny byly detekovány v 36% vzorků shromážděných v letech 1999-2005 v 40 úpravnách vod v České republice. Microcystiny byly detekovány v 27% vzorků upravené (pitné) vody a 9% vzorků mělo koncentrace microcystinů vyšší než 1 mug/L (tj. vyšší než hygienický limit pro microcystin-LR). Maximální stanovená koncentrace microcystinů v pitné vodě činila 7,8 mug/L.
