摘要:
在获得费氏弧菌(Vibrio fischer)相对发光强度与重金属离子浓度关系的基础上,采用响应面分析法建立相对发光强度与土壤联合毒性的数学模型.同时,对五处正在从事生产的工厂土壤进行采样检测验证模型的可行性.结果表明:通过建立的模型成功得出五处采样地点的土壤状况.其中,五处采样点中浅层土生物毒性均大于深层土,同一工厂排污口和生产车间之间土壤生物毒性差异较小;各采样点土样中的离子联合毒性均位于模型中的Ⅱ级毒性区间,相当于重金属离子含量为0.01 mg·L-1.说明,该模型可用于初步判断土壤生物毒性.
Abstract:
Based on the relationship between the relative luminous intensity of Vibrio fischeri and the concentration of heavy metal ions, a response surface analysis method was used to establish a mathematical model between the relative luminous intensity and the soil combined toxicity, and the feasibility of the model was verified by sampling and testing of the soil from five factories that were engaged in production The result shows that the soil conditions at five sampling sites are successfully obtained through the model. The biological toxicity of top soil is greater than that of deep soil, and the difference between the sewage outlet and the production workshop of the same factory is small. The combined toxicity of the ions in the soil samples at each sampling point is located in Grade Ⅱ toxicity interval in the model, which is equivalent to a heavy metal ion content of 0.01 mg·L-1. This means the model can be used for the preliminary judgment of soil biological toxicity.
