N -Alkyl- N -methylmorpholinium and N -alkyl substituted 1,4-diazabicyclo[2.2.2]octane (DABCO) based ionic liquids (ILs), N -alkyl-DABCO, bearing short alkyl chains are characterised by a low toxicity to Vibrio fischeri , although toxicity significantly increases on increasing the alkyl chain length. Alkyl chain length affects also biodegradability in the 28 days tests; the higher level of biodegradation was found in both the series in the case of the ethyl (C2) derivatives. In the case of N -ethyl DABCO based IL, although biodegradability is still around 40%, and consequently this IL cannot be classified as “readily biodegradable”, this value is similar to the more biodegradable functionalized imidazolium based ILs.
