cze	ICP-OES metoda pro stanovení zinku v Enchytraeus Crypticus a agarosovém gelu z ekotoxikologických testů	Byla navržena jednoduchá ICP-OES metoda pro stanovení zinku v Enchytraeus crypticus a vzorcích agarózového gelu z ekotoxikologických testů. Enchytraeus crypticus jsou odděleni, promyti vodou a rozpuštěni v tetramethylamoniumhydroxidu. Gel je rozpouštěn v HNO3. Limity detekce v mg kg-1: 0,90 u biomasy Enchytraeus crypticus, 14 pro jeden červ Enchytraeus crypticus a 0,001 pro gel). Bioakumulační faktory byly 57 - 180 pro ZnCl2 a 23 - 65 pro ZnO-NP.

eng	The ICP-OES method for determination of zinc in Enchytraeus Crypticus and agarose gel from ecotoxicological tests	A simple ICP-OES (inductively coupled plasma optical emission spectrometry) method for determination of zinc in Enchytraeus crypticus and agarose gel samples from ecotoxicological tests is proposed. The Enchytraeus crypticus individuals are separated, water-washed, wet-weighted and dissolved in tetramethylammonium hydroxide. The gel is digested in HNO3. The method (limit of detection in mg kg-1: 0.90 for Enchytraeus crypticus bulk biomass, 14 for one Enchytraeus crypticus worm and 0.0018 for gel) was employed in evaluation of ZnO nanoparticles (ZnO-NPs) compared to ZnCl2: bioaccumulation factors were 57 – 180 for ZnCl2 and 23 – 65 for ZnO-NPs.
