Acute toxicity resulting from exposure of Poecilia reticulata to several ionic liquids have been evaluated. It was analyzed, according to OECD guidelines, P. reticulata survival in response to concentrations of 100 mg L -1 of 1-etyl-3-methylimidazolium chloride [EMIM][Cl], 1-butyl-3-methylimidazolium chloride [BMIM][Cl] and 1-hexyl-3-methylimidazolium chloride [HMIM][Cl], considering that increasing alkyl chain length is a major factor in determining toxicity. It were observed also behavior changes of fishes during the test period. It was realized a comparison between toxicity parameters obtained on different test systems - enzyme acetylcholinesterase, promyelocytic leukemia rat cell line IPC-81, freshwater crustacea (Daphnia magna), saltwater bacteria (Photobacterium phosphoreum) and nematode (C. elegans) - for the studied ionic liquids. The results support the choice of such an assay for the prospective risk assessment of these compounds.
