Ionic compounds (ionic liquids)
Partitioning of ionic liquids in cell-based assays
Ionic liquids (ILs), are gaining a broad interest due to their desirable physicochemical properties and the ease of tailoring of these properties by combining cationic and anionic moieties with different substituents. They are also classified as “green” or “sustainable” chemicals because of their negligible vapor pressure and non-flammability. However, with the expanding number of studies on the toxicity and biodegradability of ILs, we are now aware that some ILs can be very hazardous. This project focuses on mechanistic investigations of modes of toxic action of a broad, structurally diverse group of ILs to support the evaluation of their environmental hazard. A further goal is to measure environmental or physiological partitioning properties such as the membrane-water or protein-water partition coefficients. Combined, these approaches will enable a re-evaluation of the reported toxicity data which considered only the nominal concentration and were based on apical endpoints. The research can be expanded to develop a prediction model for the toxicity and bioaccumulation potential of ILs so that we can have a pro-active screening of new, emerging compounds in the future.

Ionic liquids can be used as alternative plant protection measures which, unlike conventional pesticides, do not affect directly the insects or other pathogens (and may in this way contribute to biodiversity protection in agricultural areas) but stimulate plants to defend themselves.
