title: Study on mutagenicity and identification of organic pollutants in wastewater of industrial area.
abstract: In this study, wastewater samples from three industrial wastewater channels and 12 related factories were collected. Nonvolatile organic chemicals were concentrated on H-103 resin and analysed by GC/MS/DS techniques. The mutagenicity of organic extracts from the samples was examined by using S. typhimurium assay (Ames test). The results of both Ames test and chemical analysis showed that the mutagenic compounds in the Loujia Channel mainly come from Dyestuff Factory, and that Pharmaceutical Factory is a main pollution source of mutagenic compounds for the Xindun Channel. Our experimental results also showed that it is necessary to examine the mutagenicity of industrial wastewater by using short term bioassay for evaluating long-term effect of industrial wastewater on human health.
