Although considered as “green” solvents, the toxic effects of ionic liquids (ILs) on organisms have been widely investigated in recent years. However, studies on the toxic effects of ILs on plants all focus on toxicity in nutrient solution. In the present paper, the toxic effects of 1-butyl-3-methylimidazolium chloride ([C4mim]Cl) on Vicia faba seedlings in soil at 0, 500, 1500, and 2500mgkg−1 on day 10 were studied. The present results showed that the growth of V. faba seedlings may be seriously inhibited when the IL concentrations were higher than 500mgkg−1. The EC50 values for shoot length, root length, and dry weight were 3886, 2483, and 3359mgkg−1, respectively. In addition, [C4mim]Cl caused lipid peroxidation and DNA damage at 500mgkg−1 and oxidative stress at 1500mgkg−1, which indicated that [C4mim]Cl may have genotoxicity and cytotoxicity on V. faba seedlings. Moreover, oxidative damage may be the main toxic mechanism of ILs.
