Ionic liquids (ILs) are called "green" solvents, which are due to their unique physicochemical properties and potential applications in various areas. However, the toxicity of ILs has attracted increasing attention from scientific researchers. The present paper studied the toxic effects of 1-octyl-3-methylimidazolium hexafluorophosphate ([C8mim]PF6) on wheat seedlings at 0, 1, 2, 4, 6, and 8 mg l(-1) on days 7, 10 and 13. The present results showed that the growth of wheat seedlings was seriously inhibited when the concentration was higher than 2 mg l(-1) and the inhibitory effect enhanced with increasing concentration and time. The EC50 values for germination, shoot length, root length and dry weight were 11.104, 5.187, 4.380 and 6.292 mg l(-1), respectively. [C8mim]PF6 could cause an increase in the production of ROS, which led to the oxidative damage and lipid peroxidation. Furthermore, these toxic effects on wheat seedlings were irreversible.
离子液体 (ILs) 被称为“绿色”溶剂，这是由于它们独特的物理化学性质和在各个领域的潜在应用。然而，ILs 的毒性引起了科学研究人员越来越多的关注。本文研究了浓度为 0、1、2、4、6 和 8 mg/L 的 1-辛基-3-甲基咪唑六氟磷酸盐 ([C8mim]PF6) 在第 7、10 和 13 天对小麦幼苗的毒性作用。结果表明，当浓度高于 2 mg/L 时，小麦幼苗的生长受到严重抑制，且抑制作用随浓度和时间的增加而增强。发芽、苗长、根长和干重的 EC50 值分别为 11.104、5.187、4.380 和 6.292 mg/L。[C8mim]PF6 会导致 ROS 生成增加，从而导致氧化损伤和脂质过氧化。此外，这些对小麦幼苗的毒性作用是不可逆的。
