In this article there is discussed the influence of ionic liquids on natural environment on the basis of detailed analysis of the literature information and the results of the Authors' researches carried out within the framework of the development and research project no. PBR/15-249/2007/WAT-OR00002904 financed by Ministry of Science and Higher Education during 2007-2011. The literature information about toxic features of ionic liquids is very skimpy, but the detailed analysis of it and the results of our own researches allow us to say that not all ionic liquids should be treated as fully environmentally friendly substances. Among these substances, there are non-toxic and moderately toxic but there are very toxic liquids, too. Therefore, uncritical rating all ionic liquids among Green Chemistry is inappropriate. The test results of ionic liquids ecotoxicity were compared with the results obtained for standard oils used at lubrication technologies, particularly at motorization. All reference oils, according to EU classification, were non-toxic. The tests were carried out in accordance with OECD 202 European normative document, which recommends carrying out the tests for Daphnia Magna crustaceans. There were carried out: acute immobilization tests to Daphnia Magna, calculation of the effective concentrations EC50-t and evaluation of ionic and reference liquids toxicity with regard to used bioindicators
