摘要: 采用小麦和大麦为受试作物,以其在受试化合物污染的土壤中培育3 d后获得的根伸长的半数抑制浓度(IC₅₀)评价了12种酚类化合物的毒性效应。结果表明,在所设浓度范围内,酚类对作物根伸长均存在剂量-效应关系。小麦对受试酚类的IC₅₀范围为:12.92-231.76 mg·kg^-1,其中邻苯二酚只在最高浓度500 mg·kg^-1时对小麦的毒性效应显著。大麦对受试化合物的IC₅₀范围为:7.15-478.31 mg·kg^-1。小麦对3-甲基酚、双酚A、2-萘酚和壬基酚相对敏感,而其它8种化合物则是大麦相对更敏感。酚类化合物对小麦和大麦的毒性强度整体趋势一致。

Abstract: To evaluate the toxic effects of 12 phenols, the root elongation of wheat and barley after exposure to different concentrations of phenols were investigated. Results showed that root elongation was significantly inhibited with the increasing of phenol concentration. The IC₅₀ (half maximal inhibitory concentration of root elongation) was used as an indicator. The IC₅₀ values ranged from 12.92 to 231.76 mg·kg^-1 for wheat and between 7.15 and 478.31 mg·kg^-1 for barley. For pyrocatechol, significant inhibition of root elongation for wheat was observed only under the highest concentration of 500 mg·kg^-1. Wheat was relatively more sensitive to 3-cresol, bisphenol A, 2-naphthol and nonylphenol, while barley was more sensitive to other phenols. In general, the rank of phenols toxicity on wheat was similar to that of barley.
