【Abstract】 In this study ,nonvolatile organic pollutants in four kinds of chemical industrywastewater were concentrated and eluted from DA4 resin. The mutagenicity of orgenic ex-tracts from these samples were examined by three assays :Ames ,SOS and rate of micronucle-us in blood cell of fish.The results showed that four sources of sewage excreted from chemi-cal industries contain substantial mutagenic substances,especially those excreted dye indus-try and petroleum refinery.更多还原
