| 摘 要： | 本文利用发光细菌法研究了土壤水提取液中2种汽油(90#和93#)的生物毒性。提取液中90#和93#汽油分别在63.2~90.1mg/L和62.7~91.1 mg/L范围内有较高的生物毒性,并随浓度的升高而增强,90#和93#汽油的土壤水提液EC50值分别为83.5 mg/L和83.7 mg/L,在土壤中的临界值为2308 mg/kg和3678 mg/kg。这些结果为发光细菌毒性测定方法在石油产品污染土壤生物毒性评价中应用提供了可能性。

| Abstract: | Biological toxicity of two kinds of gasoline (90# and 93# ) in soil extracting solution was studied with the help of luminous bacteria. It was high when the concentration of 90# and 93# in the soil extracting solution reached 63.2~90.1 mg/L and 62.7~91.1 mg/L, respectively, and increased with the concentration. EC50 of 90# and 93# in the soil extracting solution was 83.5 mg/L and 83.7 mg/L, respectively. The critical concentration of 90# and 93# in the soil was 2308 mg/kg and 3678 mg/kg, respectively. The results of the study make possible the application of the method of using luminous bacteria to assess biological toxicity of petro-products polluting the soil. |
