摘要/Abstract

摘要： 测定了草甸棕壤条件下,菲、芘对小麦、白菜、西红柿3种植物根伸长抑制率,以及复合污染毒性效应.结果表明,菲、芘浓度与植物根伸长抑制率呈显著线性或对数相关(P=0.05).2种有机物对植物根伸长抑制强度为菲＞芘.这与菲、芘的水中溶解度明显相关.与土壤脱氢酶活性和蚕豆根尖微核实验结果相比,植物根伸长对菲、芘毒性更敏感.小麦为有机污染的最敏感指示植物.菲、芘复合污染产生明显协同作用.

Abstract: The inhibition rates of phenanthrene, pyrene on wheat, Chinese cabbages and tomatoes were determined in the meadow brown soils. The toxicity effects of combined pollution were tested. Results indicated that there was a significant line or logarithmic relationship between the concentration of phenanthrene and pyrene, and the inhibition rates of plants(P =0.05). Inhibition of these two chemicals on plant elongation was phenanthrene >pyrene, which was closely related with the water solubility of these chemicals tested. For the toxicity of phenthanthrene and pyrene, root elongation was more sensitive than the activeness of soil dehydrogen and the MCN. Wheat was found to be the most sensible indicative plant. When phenanthrene and pyrene were combined, an obvious synergism effect was observed.
