Using of organism Eisenia foetida in ecotoxicity tests
 Modlitbová, Pavlína ; Vávrová, Milada (referee) ; Zlámalová Gargošová, Helena (advisor)
Pesticide products used for plant protection are one of the chemicals that are intentionally brought into the environment. In Czech Republic there are legally used only those pesticide products, which are registered by SRS (State Phytosanitary Administration). For registration of these products there is required in addition to assessing the likely negative effects on human and animal health, also information whether the pesticide products negatively not affect the environment, in particular avoiding the contamination of aqua system or not effect the non target organisms. This master's thesis discuss the use of organism Eisenia foetida (redworm) in the contact ecotoxicity tests by testing pesticide products. There were selected such pesticide products where there are not solid information about their impact on non-target soil organism (Eisenia foetida) and based on literature research was chosen ecotoxicity test by OECD 207 method, the acute toxicity test which is in place for 14 days. Two pesticide products Topsin M 500 SC (active ingredient thiophanate-methyl) and Perfekthion (active ingredient dimethoate) were tested. Ecotoxicological values were calculated and ecotoxicity of such peticide products for soil organism were avaulated.
