摘　　要：以国际标准生物指示物斜生栅列藻为实验生物,采用相加指数法,在单一毒性基础上进行1:1的浓度配比实验,研究了丙酮与15种酮类化合物的联合毒性。结果表明:丙酮和环己酮、环戊酮、3-戊酮、苯丁酮、4-硝苯乙酮、间硝基苯乙酮、硝基苯乙酮表现为协同作用,丙酮和乙酰乙酮、丁酮、2,3-丁二酮、苯乙酮、间氨基苯乙酮、2-辛酮、2-癸酮、4-氨基苯乙酮表现为拮抗作用。International standard indicator organism-scenedesmus obliquus was used as experimental organism, and Additive Index method was applied to calculate AI value. According to individual toxicity of ketons, aceton and 15 kinds of ketons were tested under the same ratio concentration. The results show that .the joint toxicity of acetone and Cyclohexanone, Cyclopentanone,3-Pentanone,Benzylacetone,4-Nitroacetophenone,3-Nitroacetophenone,Nitroacetophenone is synergistic respectively, while the joint toxicity of acetone and Acetylacetone,Butanone,2,3-Butanedione,Acetophenone,3- Aminoacetophenone,2-Octanone, 2-Decanon, 4-Aminoacetophenone is antagonistic respectively.
