Effect of Ionic Liquids on the Hatching of Artemia salina Cysts

Abstract

We investigated the effect of six ionic liquids (ILs), and dimethylsulfoxide (DMSO) as a typical molecular liquid (organic solvent), on the hatching of Artemia salina cysts. The effect of an IL on the hatching of Artemia salina strongly depends on the specific combination of cation and anion. Of the ILs tested, choline acetate and choline chloride had a significantly lower toxicity. The level of inhabitation followed the order [chl][dhp]>[bmim][NO3]>[MAN][NO3]>[bmim][Ac]> DMSO>[chl][Ac] ≥ [chl][Cl].
