摘要
本文应用Ａｍｅｓ试验和ＳＯＳ显色法２个细菌测试系统研究了广州南部流域某些河段水中有机物的遗传毒性．１３个水样中，４个可诱导鼠伤寒沙门氏菌组氨酸缺陷型菌株的回复突变；６个可诱导大肠杆菌的ＳＯＳ反应；２个水样在２个测试系统中均有诱导作用．结果还表明；采集的水样量及受试物的配制对试验结果有显著影响；在ＳＯＳ显色法中，ｕｖｒＡ菌株和ｕｖｒ＋菌株对相同水样有不同反应。
In a survey of a new source of water supply,the
genotoxicities of organic ex-tracts of water samples taken from rivers in south areas of
Guagzhou were studied withSOS Chromotest and Ames Test. Of all the 13 sampls tested,6
induced SOS rection ofE.coli tester strain PQ37,4 induced reversion of Salmonella tester
strains, 2 showedpositive reaction in both bactcterial testing systems The present studies
showed that theamountof the water samples and the way the samples were made affected the
results of thegenotoxicity studies and that in SOS chromotes uvrA strain and、uvr strain
differed in theirreaction to the same water samples.
