Ecotoxicological evaluation of ethylammonium nitrate and aluminium salt mixture

The ecotoxicity of a mixture of the ionic liquid ethylammonium nitrate (EAN) and aluminum nitrate salt (Al(NO3)3) as well as the corresponding to pure components was studied in this work. This mixture has singular interest as electrolyte in electrochemical applications and data about the effects of mixture and components on the environment can hardly be found in literature. Changes on the bioluminescence of the Aliivibrio fischeri (Beijerinck) Urbanczyk bacteria through Microtox®test and on microbial activity, measured by microcalorimetry, of two soils with different organic matter content, when exposed to solutions of different concentrations of these compounds, were analyzed.This work was supported by Spanish Ministry of Economy and Competitiveness, MICINN, ERDF and FEDER Program through the projects MAT2014-57943-C3-1-P, MAT2014-57943-C3-3-P, MAT2017-89239-C2-1-P and AGL2017-86075-C2-2-R, as well as by Xunta de Galicia through GRC ED431C 2019/07 and ED431C 2020/10, SRC (ED431E 2018/09) and IN607A 2017/6 projects and the Galician Network of Ionic Liquids (ReGaLIs) ED431D 2017/06.
