Are Ionic Liquids Toxic

There is no way to answer this question in a general vray. Since ionic hquids can consist of so many chemically different types of cations and anions this question has to be answered case by case. The magic ionic hquid which meets all requirements in toxicity, ecotoxicity, stability and performance simply does not exist. Up to now there is still very limited information available regarding a full toxicological profile of ionic liquids. However, recently some valuable data have been published [27]. These data were collected for the notification process of the corresponding ionic liquids and represent examples from the most common classes of cations EMIM, BMIM and ammonium (Table 9-3).

Biological degradability not readily degradable not readily degradable readily biodegradable 

Toxicity to daphniae autelytoxic acutely not harmful acutely not harmful 

Toxicity to fish acutely not harmful — acutely not harmful
