%X Ionic Liquid (IL), combination of an organic cation with an organic or inorganic cation, possess some remarkable physical chemical properties such as no virtual vapor pressure (allowing recyclability and reusability), wide liquid range, high thermal and chemical stability, ease to choose hydrophobic/hydrophilic character and wide electrochemical window. Owing to that, they have become increasingly popular as green solvents/additives/catalysts for organic synthetic chemistry, extraction, electrochemistry, catalysis, biomass conversion, biotechnologies and pharmaceutical applications. This is acknowledged by the exponential number of yearly published articles related to them. However, even if these are very widely studied in the international scientific community, they are not or very little used on an industrial scale, particularly because of the lack of data on their toxicity and biodegradability. Notably hydrophobic ILs seems to display higher toxicity towards microorganisms and lower biodegradability compared to their hydrophilic analogues since they are not readily disassociated in water. This present work aims to explore the biodegradability of 8 different insoluble ILs in different sources of water bearing varied amount of microorganisms to study the impact of the used water on the biodegradability assessment. The water sources used are Type III Water, Pond water and filtered Sewage Water. Based on the results obtained, it can be concluded that the type of water has a very minor influence on the biodegradability effect of insoluble ILs. However, there is still some degree of influence on the type of water with the biodegradability. © 2016 Author(s).
