Abstract

1-(2-hydroxyethyl)-3-methyl imidazolium chloride [IM12OHCl], 1-(3- hydroxypropyl)-3-methyl imidazolium chloride [IM13OHCl] and 1-(6-hydroxyhexyl)- 3-methyl imidazolium chloride [IM16OHCl] have been synthesized in the laboratory by reacting 1-methylimidazole with 2-chloroethanol, 3-chloropropanol, and 6- chlorohexanol, while 1-(2-hydroxyethyl)-3-ethyl imidazolium chloride [IM22OHCl] has been synthesized by reacting 1-ethylimidazole with 2-chloroethanol. The toxicity of these ionic liquids are determined according to OECD Guideline 203. Six aquarium filled with 5 L of lake water are prepared. The water temperature is kept at 23 ±1 °C and aerated to restore the concentration of dissolved oxygen to at least 60% of its air saturation value. 10 fish are placed in each aquarium and the aquariums are kept under normal laboratory illumination with a daily photoperiod of 12 h. A limit test is performed at the concentration of 100 mg L-1 of each synthesized ionic liquid and left for 96 hours. After 96 hours, 2 fish died in the aquarium containing 1-(2-hydroxyethyl)- 3-ethyl imidazolium chloride, while no fish died in the other aquariums. The full toxicity test according to OECD Guideline 203 is performed using 1-(2-hydroxyethyl)- 3-ethyl imidazolium chloride at five concentrations from 20.0 to 100.0 mg/L and result shows that no fish died. It is concluded that all the four ionic liquids tested are non-toxic to freshwater fish
