Abstract:In this paper, the effects of three imidazolium ionic liquids, 1-butyl-, 1-octyl- and 1-dodecyl-3- methylimidazolium chloride on the inhibiting concentration to the growth of brine shrimp in artificial sea water were carefully studied. At the same time, toxic organics such as methanol and acetonitrile and toxic inorganics like potassium dichromate were selected as positive control for the investigation of the effect of ILs on the brine shrimp. Dose-response curve fittings were established for the ionic liquids and the positive control toxins. The experimental results showed that with increasing the alkyl chain length of the ionic liquids, their toxicity to brine shrimp accordingly increased (LC50-24h values were 171.1, 133.6, 17.76μg/mL for the three ionic liquids, respectively). The LC50-24h values of the three imidazolium ionic liquids were found to be 10-2 to 10-3 of the values of methanol and acetonitrile while being much close to that of potassium dichromate.
