摘 要: 为探讨细菌学测试和化学测试两类方法在评价水源水有机物污染程度和潜在危害上的关系,用 S O S 显色法研究了珠江某自来水原水8 个水样有机提取物诱导的细菌 S O S 反应,并用模糊综合评判法分析了水样的 B O D 、 Hg 、 Pb 、 Cr 等化学指标.两个水样诱导了大肠杆菌 P Q37 的 S O S 反应.比较水样对细菌的 S O S 反应诱导系数与化学污染的模糊综合评判结果后显示, S O S 显色法这一细菌学短期测试系统与化学测试方法对水质的定性评价具有一致性、互补性和差异性,模糊综合评判法的应用可作为比较和解释这两类不同测试系统的分析结果的一种途径. To reveal the relationship between two analytical systems(bacteriological test and chemical analysis systems) in the evaluation of organic pollution and potencial hazard degrees of source water, SOS chromotest was applied to 8 samples of the organic extracts of source water from Pearl River in south China, and fussy synthetic evaluation of the chemical indexes such as BOD,Hg,Pb and Cr of the same source water was performed. Two of the 8 samples induced SOS reaction of the E.Coli tester strain PQ37. The comparison between bacteriological SOS reaction induction factor and the results of fussy synthetic evaluation of chemical pollution of the water showed the conformity, complementarity and difference of the bacteriological test or the SOS chromotest system and the chemical analysis. The use of fussy synthetic evaluation can be a way to compare and interpret the results of these two analytical systems.
